In the first three parts of this long piece (one, two, three), I outlined how our economic common sense has changed since the economic crisis of late 2008; monetarism/supply-side economics has given way to some newer version of Keynesianism.  I went on to claim that a primary focus on carbon pricing shows traces of the idealized vision of the market that one finds in the “free market” schools of economics; climate activists have pinned most of their hopes on carbon pricing to remedy the singular catastrophic market failure of unaccounted-for carbon emissions.  In part 4, I pointed out that there are two other important market failures which block effective action on climate in the US and elsewhere.  We then have the following list of market failures that are relevant to climate and energy policy:

  1. Externalization of costs of climate change attributable to carbon emissions
  2. Externalization of costs of infrastructure building and maintenance and high fixed capital costs of long-term private capital investment
    1. Deployment of capital intensive clean energy technologies
    2. Coordination of management and finance of upgrades to electric grid.
    3. Re-design and electrification of transport infrastructure
  3. Externalization of costs of scientific research and development

Outline of a Comprehensive Climate and Energy Policy

A comprehensive climate and energy policy is motivated by the emerging crisis in our climate, as we are rapidly approaching tipping points in the self-regulatory processes of our climate system.  Significant melting of Arctic and Antarctic ice sheets will increase the absorption of the sun's radiation and spur further warming.

A comprehensive climate and energy policy is motivated by the emerging crisis in our climate, as fossil carbon in the atmosphere is unbalancing the self-regulatory processes of the climate system. Significant melting of Arctic and Antarctic ice sheets will increase the absorption of the sun's radiation and spur further warming.

A comprehensive climate and energy policy can allow for differentiated roles for national states, regional and local governments, and for private businesses and individuals with differing potential contributions to reducing carbon emissions and building a 21st century sustainable economy.  Thus a view of economies as not just a uniform collection of individual actors responding to a pricing regime makes the picture more complex but also potentially more effective.

Assumptions

  1. A reversal in emissions trends is necessary within the next 5 years
  2. Sharp reductions in emissions are necessary within the next 10 years
  3. A “glide path” to zero net emissions needs to be entered into within the next 3 years, there is no time for commitment to new long-lasting infrastructure with incremental reductions.
  4. The US and the world population are generally not yet ready to pay anything more than a fraction of the externalized cost of current carbon emissions.
  5. Uncertainties and changes in economic theory and assumptions require an examination of the degree to which climate policy contains disputed assumptions about economic behavior change and investment behavior.
  6. Government policy and leaders have a key role in addressing failures of the market to respond to challenges both internal to and external to the market.
  7. Costs and benefits of government policies and expenditures must be adequately explained and accounted for by policymakers and political leaders.
  8. The economically stimulative effects and benefits of a comprehensive policy will either match or exceed its net costs for the United States, involving outlays and revenues in the area of several trillion dollars over the period of a decade.


“Traditional” Regulation (partially addresses “Market Failure 1”)

The power sector is particularly used to and suited to traditional regulation as the building and maintenance of power plants is highly regulated in almost every country in the world.  The private companies that operate power plants and utilities see regulation and regulators as just one cost and part of their business.

The power sector is particularly used to and suited to traditional regulation as the building and maintenance of power plants is highly regulated in almost every country in the world. New regulations are sometimes feared and resisted but enough pressure and negotiation can make most rules effective in ways that are more difficult in other economic sectors.

If governments can and at times must take a leadership role in managing the economy, they can do so in part by imposing laws that are in our long-term benefit.   Especially if ample consideration is made of the resulting costs and administrative overhead required to implement laws and new rules, these new rules can remove long-standing barriers to making progress in the area of energy, energy efficiency and climate protections.

We have seen that carbon pricing was proposed as a means of avoiding some of the supposed bureaucratic drawbacks of traditional regulation.  As it turns out in the case of sulphur dioxide that traditional regulation that dictated the installation of emissions scrubbers was, in some countries, more effective than the US cap and trade system in reducing acid rain pollution.  In addition to a fascination with a particular partial economic model, relying on carbon pricing alone might be simply an abdication of the authority of government in the face of resistance by industry.  Sometimes leaders need to “put their foot down”, if there is an overwhelming case to be made for new rules made and administered wisely.

  1. Coal Plant Moratorium – The primary regulation that must be a part of a comprehensive climate and energy policy is a moratorium on new coal-fired power plants without carbon capture and sequestration.  If power utilities find this onerous, they must lobby for regulations and subsidies that make this possible for them on all levels of their businesses.  There is no time to wait for the erection of a carbon pricing system to “suggest” that this should happen through an array of artfully calibrated disincentives.
  2. Utility Revenue Decoupling – An additional key regulation that is often overlooked is decoupling the revenues of investor-owned power utilities from the amount of energy sales, which is the regulatory regime in California.  This allows power utilities to participate in energy efficiency projects as it carries with it a fairly significant financial incentive for them to cut energy use by end users as they receive higher power rates the subsequent year from the public utilities commission if they have achieved their goals.
  3. National Building Codes that Meet or Exceed California Title 24 – California has led the nation in energy efficiency requirements for new buildings and renovations with its Title 24 standard.  A much more ambitious standard that would require a revolution in the home construction and renovation industry in the US would be to adopt the passive house standard in which space conditioning costs are slashed by 80 to 90%.  Additionally “smart codes” may help urban planners and developers site and build buildings and communities with lower total energy requirements by developing “in-fill”.
  4. National Renewable Electricity Standard (as Target) -  The adoption of a percentage minimum renewable energy for the national electric grid- is productive as long as it is
    1. ambitious (25% or greater by 2020),
    2. paired with substantial finance support for renewable energy,
    3. a rising percentage of renewable energy projects are built as replacements for fossil resources (dispatchable or synchronous with power demand)
    4. is pro-rated based on renewable resource base per region thereby balancing risk between regions dependent on their resource wealth.
  5. This "passive house" in not so sunny Germany uses high performance windows, very tight construction, super-insulation, and a ventilation system that keeps interior air fresh without losing much heat or cool.  Sunlight, heat from appliances, and people keep these houses warm on all but the coldest days and cool in the summer.  Using passive houses in the US would slash heating and cooling costs by 80% or more.

    This "passive house" in Germany uses high performance windows, very tight construction, super-insulation, and a high-throughput ventilation system that keeps indoor air fresh without the need for much re-heating or re-cooling. Sunlight, heat from appliances, and people keep these houses warm on all but the coldest days and shading, insulation and the ventilation system keeps out hot air in the summer. Building or renovating homes and commercial buildings to passive house standards in the US would slash heating and cooling costs by 80% or more.

    National Energy Efficiency Standards – Utilities and government can be mandated to cut energy use by an aggressive percentage per 4 year period (10-15%).  As in California, a portion of electric rates collected can be used to pay for a portion of the efficiency upgrades in the form of rebates.   Additionally the Energy Star program and minimum efficiency standards for hard goods should be expanded and made more aggressive. A carbon price can hasten the implementation of an efficiency standard by raising the price of energy.

  6. Aggressive Auto Efficiency Standard (CAFE) - Without high fuel prices, auto efficiency standards are difficult to impose as buyers tend to demand larger, less efficient vehicles.  Still, an efficiency standard can create targets based on engineering best practices that may help automakers plan their auto line as well as function as a public expression of intent.

From a position of government authority but responsiveness about the imposed costs and implementation path, governments can generate new direct regulations that may be as effective or more effective than existing instruments.  If we believe that government has a regulatory role in financial markets, it makes sense to consider how effective rule-making by the government has in the past and can continue to spur economic progress in the area of energy.

Effective Carbon Pricing (partially addresses “Market Failure 1”)

If we take away the expectation that carbon pricing will across the board address all key issues related to a future looking carbon policy, we can more easily define the parameters that would make a carbon pricing system effective.  A carbon pricing model assumes a market of independent actors who have choices to make as to how to structure their business and private lives, which the price will influence to emit less carbon.  Secondarily, depending on a still unfinished political process, the collected revenues may either function to displace other taxes, return a dividend or finance clean energy projects.  The following then should be criteria by which the effectiveness of a carbon pricing policy should be judged (all carbon pricing systems will not qualify for every criterion):

  1. Noticeably effects the price of fossil energy, carbon intensive products, carbon emitting activities and land-use practices whether in or outside the current market.  Must inflict some economic “pain” in its first edition in order to be effective and this pain has to have information value for market participants.
  2. Through this pricing. increases the desirability of lower or non-carbon emitting activities and products
  3. Enables effective choice of a broadening category of lower carbon alternatives on economic grounds alone
  4. Signals a will to curb carbon emissions among the leadership, and additionally inspiring voluntary “above and beyond” cuts in carbon emissions.
  5. Creates a competition between carbon emitters to emit less than their peers.
  6. Generates a revenue stream and incentive structure for allowing movement towards or maintenance of carbon sequestering land use practices
  7. Enables an international trade in or regulation of trade of carbon equivalents
  8. Would dampen or eliminate price volatility in the carbon price to enable effective investment planning on the basis of the carbon price and/or the revenues generated therefrom.
  9. Progressively raises carbon price in a planned sequence to exert pressure for further emissions cuts.
  10. Creates or energizes the market for carbon-emissions reducing innovations, spurring research and development.
  11. Is directly adjustable by regulators/legislators to enable the system to learn from experience.
  12. Is not so onerous to the taxpayers/consumers that it becomes politically vulnerable (this is partly a function of public outreach about the link between climate change, carbon pricing, and economic development as well as design of the system)

Carbon Pricing Instruments

At a House Ways and Means committee hearing earlier today, the options associated with carbon pricing instruments were not fully laid out for lawmakers to review the interlocking parts and options available.  The packages that were presented were “cap and investment” and “tax and dividend”…these are not the only options, policymakers can mix and match depending on how they weight the above criteria.

Pricing Determination and Administration

  1. Carbon Tax

    Grover Norquist, inspired by Ronald Reagan, is one of the main anti-tax activists in the United States.  Attitudes about the value and meaning of taxation have a had profound impact on the formulation of climate policies, including the selection of an instrument to administer the carbon price.

    Grover Norquist, inspired by Ronald Reagan, is one of the most influential anti-tax activists in the United States. Attitudes about the value and meaning of taxation have a had profound impact on the formulation of climate policies, including the selection of an instrument to administer the carbon price. The success of libertarians like Norquist in branding taxation as an almost total loss to individuals and their wealth has until recently been almost total.

  2. Cap and Trade – There are many variations to cap and trade — it is an exceedingly complex instrument and outlining all permutations goes beyond the scope of this analysis.
    1. Full Auction of Permits
    2. Partial Auction/Partial give-away
    3. Full give-away of permits (no price)
  3. “Hybrid” Cap and Trade (Price Ceiling and Floor for Permits) – a hybrid of a cap and trade and a carbon tax stabilizing the carbon price in a range.

The selection of the carbon price administration mechanism will emerge from political negotiations between the different interest groups involved.

Revenue Distribution

Any of the above instruments can be mated with any combination of the below mechanisms to distribute the revenue from either permit auctions or tax collection.  There is no inherent relationship of the carbon tax or the cap and trade systems with any particular means to use the resulting funds collected.

  1. Carbon-Emissions Mitigating Investment – devotes the proceeds of the program to emissions reduction
  2. Partial or Complete Dividend – attempts to soften the effect of rising energy and goods prices by returning revenue on a per capita basis
  3. Displacement of other Taxes/Revenue Streams – phasing out a payroll or other taxes by using carbon revenues.
  4. Need-based Dividend or Investment – focal efforts to soften the impact of carbon pricing by either a dividend mechanism or targeted investment in energy efficiency for the neediest.

The selection of the distribution mechanism has everything to do with the political design of the ultimate carbon pricing program and how it is introduced to voters and consumers.  The potential complexity of both the resulting instrument and the process by which we will arrive there makes reliance only on carbon pricing a politically risky maneuver for people who are concerned about protecting the climate.

Design, Fund, Incentivize Zero- and Lower Carbon Infrastructure and Fixed Capital Investment (Addresses Market Failure “2”)

While it would have been preferable for governments to have engaged in a full scale “countercyclical” policy of collecting tax revenue during the boom years of the last few decades to reduce debt, we are now facing a period in which it is “do or die” for economies to stimulate demand, restructure their financial systems, and halt the slide into a Global Great Depression II.  Engaging in deficit spending to build or expand existing infrastructure to halt rising carbon emissions is a worthwhile cause to risk future inflation for current and mid-term economic and environmental benefits.  Some private capital may be organized to build some of this infrastructure but with significant

The Obama Administration's stimulus package has already found a "shovel-ready" renewable energy infrastructure project in building out the transmission system of the federally owned Bonneville Power Administration to serve new wind farms in the Northwest.  Bonneville is one of a number of federal agencies that already own transmission leading from the system of federally owned dams in the West.  The National Unified Smart Grid will in all probability be partly federally owned and part privately owned.

Bonneville is one of a number of federal agencies that already own transmission leading from the system of federally owned dams in the West. Bonneville's transmission system will most probably form part of the basis of the National Unified Smart Grid, which in all probability will be part government owned and partly owned by private investors.

Different countries and regions have different infrastructure needs but for the US the following projects would add value to communities as well as represent a significant economic stimulus.   China is currently pushing ahead with a much more aggressive infrastructure program than the US, including rail building.  The selection of projects should be based on transparent criteria that include both needs assessment and short, medium and long-term cost/benefit analysis:

  1. Build an electrified passenger and freight rail network for the US
    1. Create a national rail plan that allows efficient co-mingling of freight and passenger rail along existing and new, non-HSR rail lines
    2. Grade separate existing rail lines (with multiple positive externalities associated) in high traffic areas.
    3. Build a high speed rail (HSR) network along high traffic corridors
  2. Incentivize and create the regulatory structures to build a National Unified Smart Grid to link renewable energy zones to demand centers; most likely there will be a mixture of public and private ownership of transmission.
  3. Incentivize the building of renewable electric generators through secure, premium wholesale electricity rates (Renewable Energy Payments).
  4. Rebate and tax credit incentives for energy efficiency upgrades to existing buildings.
  5. Incentivize the building of clean energy storage through incentivizing non-fossil grid ancillary services.
  6. While preserving or extending existing levels of mass transit service, electrify high traffic bus routes.
  7. Incentivize building of electric vehicle fast charge and trickle charge networks in cooperation with municipalities and utilities.

Increase funding for Clean Energy Research and Development (addresses Market Failure 3)

While the federal government has continued to fund clean energy research even through the Bush Administration, an increase in funding for research into renewable energy technologies, clean energy storage, sustainable biofuel alternatives, and cleaner, more efficient nuclear technologies are important to see if we can “leapfrog” existing technologies or reduce costs in the building of clean energy infrastructure.   Some have suggested budgets ranging from $3 billion to as much as $40 billion per year as a means of expanding scientific exploration, creativity and innovation in the area of clean energy.   If there is a reasonable chance that an innovation can open a new source of clean energy or increase the efficiency or cost-effectiveness of existing options, we should not hesitate to pursue it.  On the other hand, oversight over these budgets should keep the focus on what can pay off within the next ten to fifteen years.

The Principle of Non-Perfectability

While very simple systems may reach something called “perfection”, complex systems, including living things, social and economic systems, and the earth’s climate will never be “perfected”.  The advocates of self-regulating markets tended to treat markets as a “pure” or perfect social institution.   In chronicling so many market failures and needed programs to remedy them, I am not suggesting that policy will “perfect” the market or be able to completely address these market failures.

Purpose of a Comprehensive Policy

The purpose of this piece is to outline what a revised, reality-based economic and political framework for understanding both the course of previous energy and climate policy and the trajectory for effective future policy will look like.  The lore of a self-sufficient, self-regulating market put policymakers and clean energy advocates on the defensive and narrowed the focus largely to transforming the actions of individual market actors.  In response, efforts were made to “perfect” the market through a carbon price.  If we are to create a reality-based set of policy instruments we have to face facts both about the nature of economic models and the physical realities on which they are supposed to act.  I am supportive of the Repower America program, but feel it does not fill out enough the actual mechanisms by which it would achieve its ambitious goals, therefore the proposed framework.  A comprehensive climate and energy policy addresses both flaws in systemic functioning and problems of incentives and disincentives that cause individual market actors to continue to ignore the very serious consequences of anthropogenic warming.

“Picking Winners”: Policy Blunder or Necessity? December 12, 2008

Governor Schwarzenegger and the California Air Resources Board once publicly supported hydrogen, "picking a winner".  The current California Low Carbon Fuel Standard would avoid the appearance of doing such but would not speed the focused building of either a public electric quick-charge nor another post-petroleum fueling network.

Governor Schwarzenegger and the California Air Resources Board once publicly supported building a Hydrogen Highway, "picking a winner". The current California Low Carbon Fuel Standard (LCFS) would avoid the appearance of favoritism, despite a history of direct support for hydrogen. Advocates of plug-in electric vehicles believe that the merits of EVs warrant government support for a public quick-charge infrastructure, that would not necessarily be the outcome of the LCFS.

Listening to Science Friday on PBS recently, there was an interesting exchange between Dan Sperling, an influential member of the the California Air Resources Board (CARB) and Professor at the University of California at Davis, and Sherry Boschert, Vice President of the EV advocacy group, Plug In America.  Sperling has been known to advocate hydrogen fuel cell programs at the California state level, a stance that has historically had the backing of Detroit automakers until very recently.  Boschert and Plug-In America have been highly critical of the degree to which CARB has supported hydrogen to the detriment of battery-electric cars (BEVs) or other plug-ins (which includes EREV or PHEVs as well).   This is a version of the conflict that became part of the influential documentary “Who Killed the Electric Car”.

While Sperling in this exchange was presenting himself as an advocate of “electric drive transportation”, he mentioned a number of times hydrogen fuel cell vehicles (HFCV), which use an on-board hydrogen fuel cell to generate electricity for an electric motor to drive the wheels (a.k.a. electric drive).  Boschert pointed out that HFCV option has been used to delay and stymie efforts to deploy the much “readier” technology of plug-in battery electric vehicles for the last ten years in California and therefore around the nation.  The essence of this accusation, also popularized by the “Who Killed..” film, is that policy support and advocacy of HFCV’s blocks the implementation of any clean fuel vehicles short and medium term as HFCV technology is always ten years away from commercialization.  Boschert advocates a positive support policy for battery electric vehicles, like an embrace of public charging infrastructure for EVs by municipalities and state governments.

Sperling, though he claimed not to be opposed to supporting government EV programs, said that you didn’t want to “pick winners” in the technology derby to replace petroleum, citing the apparent disaster of corn ethanol.  Boschert countered that winners were always being picked, pointing out that HFCVs were funded by government and industry to far higher levels than battery research and battery electric vehicles.  She suggested that short of a government sponsored BEV roll-out program that there should be equal research funding for HFCVs and BEVs, though the first option was the preference of Plug-In America.

Efforts NOT to Pick Winners

The UN's climate change efforts, continued at the Bali Conference in 2007 and now at Poznan, has centered around a the market-like cap and trade system.  This is an effort, following the economic vogue of the 1990's for government to act as referee but not to pick winning technological solutions to climate change.

This is an effort, following the economic vogue of the 1990's for government to act as referee but not to pick winning technological solutions to climate change.

In California’s debates around a number of pioneering pieces of clean energy and climate legislation and regulation, the notion of “picking winners” comes up on a regular basis as an unquestioned taboo for any measure or program.  When in a discussion, someone suggests that policy be used to promote one technology or initiative and someone else in the room opposes that technology or the type of support, the accusation that one would be “picking winners” is thrown at the advocates of a prescriptive policy.  While California has many technology specific support programs, there are also important central pieces of climate and energy regulation that are designed not to “pick winners”.  The Assembly Bill 32, (AB 32) process which is California’s Global Warming Act of 2006, has almost inevitably gravitated towards a cap and trade system, which as is the Kyoto process, an effort not to pre-determine the price of carbon, nor commit California to a particular set of technological solutions to global warming.  Accompanying this process, the CARB is also working on a “Low-Carbon Fuel Standard” (LCFS) which tries to group all reduced-carbon fuels for transport together, including electricity, mandating certain reductions in carbon content occur regardless of which fuel is discussed.  Again, no “winning” fuel is picked in the LCFS.

Designers of these policies feel they are reducing government involvement to its intent while removing arbitrary rules and decisions from the process.  In theory, the idea of “not picking winners” sounds great but, as in all things, between the conception and the realization reality intrudes.

The Theory: Government as Referee

The most influential economist of the past four decades has been Milton Friedman, who did not even believe that government would referee the marketplace.  Friedman, in the tradition of von Hayek, believed that the only legitimate role that government had was to defend the nation, protect private property and regulate the money supply.

The most influential economist of the past three decades has been the late Milton Friedman, who moved the economic profession away from advocacy of government regulation or involvement in the economy. Friedman, in the tradition of von Hayek, believed that the only legitimate role that government had was to defend the nation, protect private property and regulate the money supply, therefore his "monetarist" label.

The economic profession and economic modeling in business settings are right now at a watershed moment, where those individuals and theories which foreshadowed the precipitous downturn of the last few months are given a great deal more credence than the orthodoxy of only a few months ago.  In this period of flux, it is reasonable to think that some old assumptions may no longer hold water, at least during the period of crisis if not thereafter.

In the last three decades, economic policy and influential parts of the economics profession have tended to hold up the ideal of an almost entirely unsupervised market, where individual and corporate economic choices in aggregate would dictate the direction of economic life.  Expressing a belief in the individual or corporation as consumer and entrepreneur, these supply side or libertarian economic theorists believed that only unregulated market forces arrive at the optimal outcome.  By contrast, government is considered by advocates of this approach to be necessarily a hindrance to economic success and growth.  This view has remained largely unchallenged in both the Democratic and Republican parties until the recent financial system near-collapse and sharp economic downturn.

While the ideal of self-regulating markets has inhibited efforts at regulation in many areas of the economy, not everybody gave up on regulation even in the heyday of this ideal.  In those environments where regulation has been accepted as a necessary evil or even a desirable economic tool, there have been attempts to incorporate the ideal of the market into economic policies.  In California, which has a history of state-level energy regulation that has continued through the last few decades, policies that interfere less in the market are considered more desirable than those that dictate to private businesses what should happen.  The latter is termed “command and control”, which sounds less desirable than a “market-based” regulation scheme.

In the ideal market-based regulation, legislators, regulators, and the government executive branch develop rules that express a desired social outcome in its broadest, most abstract form and then allow private actors to try to fulfill those desired social aims in any (legal) way they can.  In the case of a cap and trade system, the notion is that the intended goal is a set amount of global warming gas emissions that will be reduced in subsequent years.  The auction system for pollution permits is the means by which businesses acquire permits to emit a certain amount of greenhouse gases.  When there are no more permits, the business can no longer pollute or face harsh fines.  As another example, California’s Low Carbon Fuel Standard, the amount of carbon in the fuel is regulated but there is no selection of which fuel is necessarily or potentially that with the lowest carbon content.

So in a market-based regulatory system, once the rules have been set in place, the government acts as a referee, enforcing the rules but otherwise allowing market actors to make their decisions within the constraints of the system.  In the case of cap and trade, there are two levels of market mechanisms built in:  one is through the bidding on pollution permits and the other is allowing businesses and individuals to figure out by themselves how they are going to reduce their carbon emissions.  The competing carbon tax concept is not an “un-market-based” solution though it removes the first level of market mechanisms as compared to cap and trade, instead allowing businesses and individuals to figure out on their own how they are going to avoid emitting carbon and therefore paying more carbon taxes.  So cap-and-trade is doubly market-based, while a carbon tax would be a more conventional regulation where government determines a social goal and shapes the market through a disincentive.

The Other Theory: Prescriptive Policies, a.k.a. “Picking Winners”

The history of nuclear power is very closely entwined with the intentions of government leaders and officials to demonstrate the peaceful uses of atomic power.  The further development of nuclear energy and the management of its legacy will continue to require strict government oversight and direct government funding.

The further development of nuclear energy and the management of its legacy will continue to require strict government oversight and direct government funding.

While there is no hard and fast line between the market-based and a prescriptive policy, there are many policies in the area of energy where government expressedly prohibits or promotes one activity/technology or another.  The longstanding US tradition of research funding for particular energy technologies is, in a way “picking winners” though the federal government has tried to spread this funding around to some extent.  In the area of lighting, for instance, certain inefficient fixtures (probe-start metal halides) will be prohibited by the US DOE for sale as new fixtures as the first of January.  The criticism by Sherry Boschert of hydrogen policy holds true:  hydrogen fuel cells have received inordinate funding in comparison to battery technology, an imbalance that historically has had the support of Detroit automakers.   Biofuel mandates in combination with the enormous subsidies for corn production and corn ethanol are prescriptive policies.

While to a self-regulating market theorist prescriptive government policies are always inefficient and, adding some rhetorical inflation, “disasters waiting to happen”, defenders of a prescriptive policy would counter that scientists and political leaders reflecting scientific and common wisdom have found that one solution is, along one or more desirable dimensions, better or substantially worse than others.  Cigarette smoking was found to cause cancer.  You didn’t wait until individual effected people discovered that they were getting sick and dying sooner if they had smoked:  government put in laws that make the sale of tobacco more difficult and mandate public warnings of smoking’s hazards.  There was a statistical relationship between smoking and cancer which market actors alone could not perceive, especially given the socially reinforcing and addictive nature of smoking.  In lighting, probe-start metal halides use more energy than pulse-start metal halides or linear fluorescents for the same light output:  this black and white finding by engineers led to an eventual step-wise ban on the sale of probe-start fixtures.

A prescriptive policy then depends on scientific knowledge to determine, before the market can discover the difference, that one course of action is more helpful than another course of action.  The trust in scientific knowledge is key for most prescriptive policies, though prescriptive policies could also rest on the consensus of political leadership or polls and perceptions of popular sentiment.  It is no wonder that declines in the authority that people attribute to scientists in the US has led to a drift away from prescriptive policies, at least in the public presentation of policy actions.  Despite the diminished prestige of science in the US pantheon of values over the past few decades, the US government is the largest funder of scientific research in the world and also, still continues to operationalize that knowledge when it comes to implementing policy.

Beyond Prescription:  Government Sponsorship

The Tennessee Valley Authority was an New Deal economic stimulus plan for the Southeast which involved the building of, among other things, hydroelectric dams on a number of rivers in the region.  Still operated by the federal government, the TVA through fossil, nuclear and hydroelectric plants sells power to local private utilities and industrial power customers.

Still operated by the federal government, the TVA through fossil, nuclear and hydroelectric plants sells power to local private utilities and industrial power customers.

A “stronger” version of a prescriptive policy is one in which the government not only prescribes a particular solution but pays in part or in full for the realization of that prescription via taxpayer dollars.  The proposed economic stimulus packages including the much-discussed Green New Deal ideas, would be government sponsored programs by definition.  Bailouts of or support packages for individual firms or industries are government sponsored prescriptions for how the economy should remain or change in the future.  Public education is a prescriptive policy that is also government sponsored:  not only should children be educated but taxes will provide the means by which they can be educated.   Most highly industrialized countries outside of the United States have more government sponsored programs than the US, particularly in the area of social welfare.  By contrast, the US government has sponsored a very large, expensive, and technologically sophisticated military relative to other countries.

In the area of energy and transport, a government sponsored program could range from a rebate program for electric vehicle purchase to as large as the building of new power plants like the Hoover Dam or TVA projects or a system of long-distance power transmission lines for renewable energy.   These facilities could either be managed by the government as part of a public power authority or be sold off to private investors to manage.  Tax credits for oil and gas exploration or renewable energy projects are also a form of government sponsorship as to pay for these credits, taxes need to be levied or programs cut in other areas.  In any case, government sponsorship contradicts even more the ideals of advocates of the self-regulating market in the tradition of Friedrich von Hayek and Milton Friedman, as government would have a hand in setting prices or enlarge its role as a provider of services.

Real Dangers of Picking Winners

Corn ethanol is now almost universally recognized as a "false" winner, that had many powerful political friends but little scientific basis for support.  Leaving aside the ethical issues of having fuel compete with food production, most scientific studies have shown that the production of ethanol from corn only nets at most 30% more energy than is input in the process.  Furthermore intense water and soil usage contribute to its overall negative picture as a fuel for mechanical devices.

Furthermore water usage and soil nutrient depletion involved in growing the corn contribute to its overall negative picture as a fuel for mechanical devices.

While in tone this piece would seem to be critical of the categorical rejection of “picking winners’,  there are some real dangers in picking winners, especially when the process is itself wrapped in an ideology of doing the opposite, i.e. NOT picking winners.  The list below are potential real dangers of picking winners keeping in mind that these are not nearly the exclusive property of this decision making system; other forms of decision making including more market-based ones share some of these drawbacks.

1)    Corruption – Picking winners if done non-transparently and without full attention to democratic principles can lead to and/or be the product of corruption.  Picking winners involves collaboration between government and industries or professions that can shade into collusion if not pursued in a deliberate fashion with full public justification.  Bribes in various direct and indirect forms can influence the selection process.

2)    “False” Winners -  Picking winners can lead to a self-justifying selection of a technology or system that ends up being of lower quality and service than another option.  Corn ethanol, with only hope and little scientific justification, became a false winner.

3)    Economic Inefficiency – As per “2”, the government or other authority that is vested with the power to pick the winner could pick a technology or system without regard for the ultimate costs of implementing that technology.  Government officials may have no mechanisms that hold them responsible for cost overruns or other inefficiencies.  The potential for inefficiency may need to be balanced against the desirability of the goal.

4)    Lack of Accountability – related to “1” and “3”, the selection of winners may occur in ways in which those who make the decisions do not experience the effects of those decisions.   Government officials, representing the people of the US, may not be able to be held individually responsible in some circumstances.

5)    Foreclosure of future technological developments – picking a winner can narrow the market opening or close it entirely for an emerging or future technology that may turn out to be superior.  Monopolistic or oligopolistic control of markets can have the same effect.

6)    Decision-making without scientific backing – A winning technology or system may be selected without access to or utilization of the best scientific knowledge available; as we shall see below the success of “picking winners” is heavily dependent on high quality science.

7)    Decision-making without Socratic wisdom – Decision makers may feel empowered without knowing what they don’t know.  Without knowing where and to what degree they are ignorant allows decisions to be made that may ultimately be short-sighted.

8)    Arrogant self-justification – in a further development of “7” decision makers may attribute to themselves the cloak of infallibility or may downgrade the wisdom and perspective of those who are outside their coterie.  These attitudes may spring from the privilege of being able to make crucial decisions in combination with a wealth of information and resources at their disposal.

9) Economic and Political Despotism – the worst case scenario upon which much criticism of state-led policies are based, is that “picking winners” is the leading edge of authoritarianism.   Despite the tendency recently in our politics to dwell on this worst outcome, government initiative in the economy does not NECESSARILY lead to despotism as we have seen with the New Deal, WWII mobilization, the Marshall Plan, the Interstate Highway System, etc.

As we shall see below, these dangers are not necessarily an ultimate condemnation of all efforts to pick winners.

Infrastructure as Prescription

Republican President Dwight Eisenhower, building on the precedent of the New Deal and the WWII mobilization, initiated the biggest public infrastructure program in American history, the Federal Aid Highway Act of 1956.  The resulting Interstate highway system has underlain much of the economic growth of the last 4 decades though has also contributed to suburban sprawl and dependence upon the automobile.

Republican President Dwight Eisenhower, building on the precedent of the New Deal and the WWII mobilization, initiated the biggest public infrastructure program in American history, the Federal Aid Highway Act of 1956. At the time, the use of tax dollars to support a government infrastructure plan was relatively uncontroversial. The resulting Interstate highway system has supported much of the economic growth of the last 5 decades though has also contributed to suburban sprawl and dependence upon the automobile.

While the ideal of the self-regulating market can be helpful in describing how consumer choice shapes truly competitive markets, a strict adherence to this ideal leaves a gap in our understanding of how energy and transportation infrastructure gets built.  Infrastructure is a good or service that underlies basic social functioning as well as the use of other goods and services.  “Infra” means “under” and infrastructure does in general support a variety of other structures or institutions that are more visible to us.  Elements of infrastructure are usually a means to other ends. In most cases, to build competing pieces of infrastructure is economically inefficient, as the label is usually applied to physically large objects linked together into a large system.  There are also only a few actors that have the resources to build infrastructure, most notably governments and some very large corporations that often operate in markets that tend towards monopoly or oligopoly. Infrastructure then tends to be a natural monopoly, either being managed entirely by the government or highly regulated by the government to prevent private companies from exercising monopoly power over consumers.  People in advanced industrialized societies have come to view a functioning infrastructure as a (free per use) entitlement or at least a relatively affordable service that operates in the background.

A mixture of social and natural scientific analysis plus educated guesswork by a few leaders in the public and private sectors is involved in planning, proposing and building infrastructure.  Likely demand for a new or existing technology is estimated and then plans are made for the necessary infrastructure to be built.  Sometimes at some point in this process, a bond measure or other financing instrument is submitted either to a legislative body, a corporate board or stockholders meeting, or to the electorate for approval, thereby engaging in a democratic or deliberative process.  As deliberative or democratic as one or another stage of the process may be,  many potential competing infrastructure concepts are not placed into a market-like competition, a process for which we have no precedent and would seem to be prohibitively time-consuming and expensive.

Financing can be arranged either through the issuance of bonds or for infrastructure built by the private sector, stock offerings may be employed.  In the end, a “prescription” for what the society needs is devised that it is difficult to shape through the iterations of consumer buying behavior that is the ideal case for a competitive market.   Once infrastructure is being built, market actors then often devise their own plans to take advantage of the new or improved infrastructure (new housing developments, businesses etc.).  The market then accommodates itself to and/or exploits the infrastructure which has been justified based on sound engineering, transport and urban planning principles.

The route of the now California voter approved high speed rail line from San Diego to Sacramento/San Francisco has been largely determined by geography and settlement patterns.  The ultimate choice of how to link the three population centers of the Bay Area to the trunk line in the Central Valley has not yet been determined.

The route of the now California voter-approved high speed rail line from San Diego to Sacramento/San Francisco has been largely determined through an analysis of geography and settlement patterns. The ultimate choice of how to link the three major cities of the Bay Area to the main line in the Central Valley has not yet been determined.

Recently there were two large public transit infrastructure project proposals that won electoral approval in California:  a San Diego to Sacramento high speed rail project and an extension of the popular BART system south from San Francisco and Oakland to San Jose.  In a society committed to life after petroleum, reducing GHG emissions, and de-congesting the roadways, it made sense to the planners and then to a majority of the voters to provide more electric passenger rail lines for both long distance and local use.  In the extension of the BART, one can project that transit-oriented residential and commercial development will be built around the new stops of this16 mile commuter rail extension.

In terms of the current discussion, in each of the California measures, a “winner” proposal was picked by a coalition of political leaders, campaign funders and transit planners and then submitted for approval to the electorate.  While there was no market competition between different alternative infrastructures, there were opponents of each of the plans that sometimes backed up their opposition with alternative ideas in various stages of elaboration and detail.  Ultimately, it is assumed that if leaders and experts put together a compelling proposal that appears to serve voter/human needs that the infrastructure project will be “good enough”.  The process of putting together a marketplace of these ideas and proposals would for both the producers of the proposals and the consumers of these proposals represent many multiples more of effort and money in just the initial stages of the projects.  To build infrastructure often requires that an operational concept of “need” be available rather than simply see infrastructure concepts as a competition of “wants” or desires, as is typical in market competition.

It would then seem that in the world of infrastructure projects, a prescriptive approach has advantages over experiments in building a market ideal or competition between proposals.  Perhaps through improved cybergovernment initiatives a more interactive proposal generation process could be designed, yet this more democratic approach is not identical to the real-world interactive nature of markets where real products and services are offered and chosen among by consumers.  Then, there may very well be something in the nature of infrastructure projects, their uniqueness, site-specificity, high expense and long duration that lends itself to leader-driven and prescriptive decision making, even as certain aspects of that process can take into account the preferences of the end users.  The changing whims and trends of markets operate on a different timeframe than persisting on over a period of  a decade or more building immense physical objects and systems.

Advantages of Prescription/Picking Winners

Here then are some of the advantages of prescriptive or government sponsored programs:

1)    Potential for rapid implementation – There are fewer stops between design and construction start if a winner has been picked.  If there is a clearcut winner why take additional steps?

2)    Potential to be oriented towards long-term viability – local, more immediate economic concerns can be balanced against any number of different factors that may represent a longer view of social value than voters or consumers can typically calculate at the voting booth or turnstile.

3)    Expense of generating multiple proposals short-circuited – In addition to time costs, there are monetary costs to generating multiple ideas for submittal to the public or to regulatory boards.

4)    Potential to be based more directly on scientific findings – As considerations of a market-based competition can be, at least in the design, avoided, more elements of scientific understanding that have no bearing on current market concerns can be considered.  Scientific findings may at times stand counter to wishes of a consumer market, as with smoking cessation or beyond the current perception of market actors, like global warming.

5)    Government can insure higher risks – with some massive earthworks and higher risk technologies government endorsement and insurance is an absolute necessity.

6)    Government can use directive policies – Some infrastructure projects require the use of public lands or eminent domain.  While there have been questions lately that notions of the public good can play a role in economic life, government and its representation of the popular will or sentiment can more legitimately represent these wishes than private corporations.

7)    Integration of varying technologies – a prescription can contain as few or as many elements as needed to fulfill the mission.  The interdependence of different technologies and roles can be contained within the infrastructure plan.

8)    Multi-factor Systemic approach – diverse factors or organizations can be added or subtracted from a prescription, externalities can be internalized and vice versa.

9)  Concrete expressions of intent – The hand of the market or the setting of abstract rules, such as those that limit emissions, do not concretize popular sentiment or support as much as the building of physical objects.

For those who are committed to an economic model that sees good coming only from the interaction of independent economic actors, the above advantages will pale in comparison to the previously listed dangers of picking winners.  However, in building infrastructure, there seems to be no way to avoid risking those dangers if we want to arrive at the physical outcomes that increasing numbers of analysts are saying are necessities.
Integrated Energy and Stimulus Plans:  Unthinkable without “Picking Winners”

Project Better Place, a Palo Alto based electric vehicle infrastructure start-up, hopes to increase the use of electric vehicles by creating a public quick-charge and battery exchange infrastructure.  Concomitant with its ambitions, this small firm must court large automakers like Renault and Nissan and governments like Hawaii or Israel to help build the appropriate vehicles and stationary infrastructure.

Project Better Place, a Palo Alto based electric vehicle infrastructure start-up, hopes to increase the use of electric vehicles by creating an integrated public quick-charge and battery exchange infrastructure. To realize its ambitions, this small firm's designs need to be selected by major industrial corporations and governments. So far, PBP has developed agreements with Renault and Nissan and Israel, Denmark and Hawaii.

The Repower America plan might be called an “integrated energy and economic stimulus plan”.  The similar proposal I have been putting forth over the past year or so, the Renewable Electron Economy, based on the engineering analysis of Ulf Bossel, that we should shift most of our energy demand to electrical devices and use renewable energy as much as possible to generate electricity is another example.  In an integrated energy plan, the general types of energy conversion devices are prescribed as are the types of energy extracting or generating devices, so there is an integrated match:  if you are proposing an “electron economy”, you want to make sure that there will be a coordinated hand-off between the demand for electricity and its supply.  Electricity, as it is difficult to store, requires a more tightly integrated system than the trade in and consumption of the stable molecules that compose fossil fuels.

The call for planning has come from a number of political quarters.  T. Boone Pickens, not previously known as advocate of economic planning, has recently promoted that the US develop a plan to get off foreign oil, bemoaning, in passing, the lack of such planning over the past 3 decades.  Pickens’ plan serves his economic bets on particular technologies but he has been public-spirited enough to suggest that planning itself was necessary and lacking in our political discourse. Plans can also emerge independent of government involvement: manufacturers of electric cars are now considering creating a standard high voltage quick-charge interface for their cars, so that all quick-charge capable vehicles will be able to use a future standard high-voltage charger.  This is analogous to standardizing the size of the aperture of fuel nozzles and gas tank mouths. In getting together on a standard, the manufacturers are picking a winner.

The Repower America plan is largely, in the terminology I use, a renewable electron economy plan.  Its ambitious goal of converting the US electrical energy supply entirely over to clean sources within a period of 10 years leaves little room for experimenting with different high-level physical or policy instrument designs.  For one, deciding that electricity should be the clean energy carrier of choice is “picking a winner”, though it is based on a growing consensus of engineers, advocates and experts on energy. Furthermore, reflecting a growing consensus, the plan suggests that there are some clear winners in the area of clean generation technology that should immediately receive government and industry support:  wind, solar thermal with storage, and geothermal energy, along with sufficient transmission infrastructure to integrate these into the existing grid.  Additionally, and in this technology choice is left more open, 28% of energy demand will be reduced through the adoption by end users of energy efficient technologies.  Along with the Repower America plan, Al Gore has supported a carbon tax yet, I believe, he has no illusions that this tax alone can drive the building of the infrastructure required to achieve the Repower America goal.

Renewable Energy Payments:  Prescribed Markets

One accusation leveled at the now ever more widely implemented feed-in-tariffs a.k.a. Renewable Energy Payments that support renewable energy is that they “pick winners”.  This is partially true in the sense of picking a broad category of clean energy technology but not true in the sense of picking individual private firms as winners.  A renewable energy payment system, like that proposed by Rep. Jay Inslee or like those now in use in many European countries, sets wholesale prices for renewable generators of a wide variety of types and sizes.  The idea is to provide investment security for builders of renewable generators that we know will generate a certain amount of clean electricity: the guaranteed wholesale, generally above current electricity market, price per kWh allows the builders to recover their investment plus a reasonable profit.  The system of cost plus reasonable profit is used frequently in the construction industry when large scale one-of-a kind projects are commissioned for a particular buyer.

The designers of renewable energy payment systems counter claims that they are not competitive or market based by pointing out that they displace competition from the deployment of generators to the manufacture of generation technologies.  In a feed in tariff system, project developers want to purchase generators that will maximize their profit, so the intended effect will be to drive the cost of renewable generators down.  A renewable energy payment system then picks certain technologies as winners but not the actual implementation of those technologies by different manufacturers. Feed in tariffs can be justified in economic terms as a prescription of payments by the consuming public for a positive externality; carbon pricing is a payment by emitters to the public for a negative externality.

A renewable energy payment system could be designed that drives the implementation of a plan like Repower America.  In this case payments would reward the building of some of the wind, solar thermal and geothermal generators required by offering higher tariffs for the desired generators.  Thus a prescriptive plan can contain within it markets for the technologies prescribed.  The infrastructure of the Unified National Smart Grid can provide a framework for multiple smaller markets for building generators and generating electricity.

Exercising Leadership with or without Carbon Pricing

If we know what is “right” in a scientific sense, given a certain goal and the constraints of reality, why not proceed to do it with necessary but deliberate haste in consultation with popular representatives?  If we are facing a potentially very deep economic crisis and are largely convinced that infrastructure projects can function as fiscal stimuli, why not charge ahead?  The aversion to “picking winners” that we have developed over the preceding three decades would seem to say:  “no, find a regulatory framework within which profit-driven economic actors will discover that there is a market for something like this and build something like it”.  The focus on carbon pricing schemes as the main motive force in transforming our economy is one more example of our aversion over the last few decades to government and to a lesser extent corporations taking a leadership role.  We, luckily or unluckily, may be at a watershed moment where leadership is now desired or even highly prized.

Carbon pricing schemes, whether cap and trade or a carbon tax, attempt to circumvent the process by which government actors and leaders in the economy would take responsibility for building large projects.  Instead they could say:  “the cap and trade system or carbon tax made me do it”.   While having an ingenious policy framework which compels actors to act both in their long-term and short-term good is desirable, it is highly unlikely that such a system will by itself initiate and finance the building of all the Repower America/Renewable Electron Economy infrastructure we will need.

To embark on a path, such as building a Repower America-like clean energy infrastructure, will require leadership, a quality that is much praised but in its actual manifestations is often controversial.  To build a Unified National Smart Grid, for instance, will require leaders or a leader, perhaps President-elect Obama, to explain to congress and the American people why we should build this piece of infrastructure now.  This also means taking responsibility for both the “upside” of this large project (jobs created, energy independence, climate protection, new technologies) and the “downside” (costs, use in certain areas of eminent domain, appearance of electrical transmission towers).  Too often, advocates of complex policy instruments seem to want their policy instrument to remove all of the ambiguities and ambivalences associated with the leadership role.

Likewise, a renewable energy payment (REP) system will require political leaders and electrical grid regulators to commit themselves to support renewable energy generators like wind turbines, solar thermal electric power plants in the desert, and photovoltaic installations on the ground and on rooftops.  Not only would the institution of such a system attempt to benefit from the virtuous appearance of clean renewable energy generators but also offer direct financial support to those generators via guaranteed and premium wholesale electrical rates.  While many support schemes sidestep the price of renewable energy by using indirect means like tax credits or carbon pricing, the REP systems name the prices and therefore require leadership to be exercised by declaring in public both the benefits and the costs of clean energy.

As recent announcements by President-elect Obama suggest, we have reason to hope that our next President will grasp the opportunity to lead the building of the necessary infrastructure we need to emerge from this economic crisis and to meet the challenges of the 21st century.

Renewable Electron Economy Part XI: Sending Coal to the Sidelines December 31, 2007

Climate scientists, environmentalists and some political leaders have been telling us that we should stop using coal to generate electricity or at least use it with the as yet untried carbon capture and sequestration (CCS) technology. James Hansen, one of the leading climatologists, has likened the trains laden with coal from Wyoming’s Power River Basin that roll through America to “death trains”, referring to the potential extinction of species as the climate rapidly changes. Al Gore and as well as other environmental advocates and political leaders around the world have called for a moratorium on new coal-fired generation without CCS. But where does this leave electric utilities in the US, Europe, Africa, and Asia who depend on present and planned coal-fired power plants to supply customers with power?

As it turns out, power companies and merchant generators are racing to permit new coal power plants in unprecedented numbers (there are now 121 plants under construction or in planning in the US), in part to meet soaring demand for electric power and, perhaps, in part to “create facts on the ground” before more stringent regulation is put in place.

What if a new coal plant without CCS moratorium was actually put in place? What if a substantial price was put on carbon dioxide emissions ($100/tonne of carbon dioxide=$367/tonne carbon)? Then conventional coal plants, depending on the type of coal they used would produce electricity costing somewhere in area of $.15 to $.20/kWh. If one or both of these “what ifs” become reality, there will be additional motivation for utilities to find alternatives to the use of coal as well as experiment with CCS and push for new nuclear plants.

What if regulators additionally placed a price premium on electricity produced by renewable power plants in particular ones that could perform like coal plants? If sustainability thus becomes an additional criterion, power companies would need to boost their bottom lines by focusing more on renewable coal-replacement alternatives rather than recuperating coal or nuclear.

All of the foregoing assumes that, in fact, electric utilities had not already voluntarily committed themselves to creating a sustainable alternative, leading rather than following, which some might. Such a position would confer a long-term competitive advantage on those companies who get themselves ahead of the game.

Why do utilities like coal? For one, it’s been cheap and very plentiful in areas with significant industrial economies, in particular the US, Russia, Northern Europe, China, India, Australia, and South Africa. Electricity from coal sometimes costs as little as $.01/ kWh with an already depreciated power plant with plentiful coal. In many regions of the world, utilities don’t worry about running out of the primary energy to generate power, because they feel they can always get more coal and have a historical relationship with the coal mining industry (they are the industry’s largest customer by far).

Furthermore, coal-fired generation technology is a known quantity. Coal-fired steam engines have been in regular use since the late 18th Century and these heat engines were retooled as electrical generators in the late 19th Century. Current technologies employ turbines and convert about 30% of the energy of the coal fire into electricity. There is on most continents an infrastructure of railways, canals or shipping that enable coal to be transported thousands of miles allowing power plants to be located nearer centers of power demand (cities and industrial areas).

Because coal is cheap, accessible, an energy store, and it takes a while to start and stop a coal fire, coal plants are used for two types of power: baseload and load-following power. Baseload power plants are on most of the time, to supply the constant baseline of power demand. Load-following power follows the daily rise and fall of power demand from the early morning to the evening. A coal plant can be set to either be constantly on at a certain level day and night or can be ramped up and down within a period of minutes. The other kind of power plants, peaker power plants for rapid spikes in power demand, require quicker responses than a coal fired plant can generate and in the contemporary power system are usually natural gas fired or hydroelectric.

To replace the functions of a coal fired power plant, a renewable power plant or ensemble of power plants would need to be economical to run and be able to run around the clock for days on end. How economical these plants would need to be would depend in part on the regulatory environment and public sentiment about the value of clean power. Additionally, the ability to ramp up production during the day would be a bonus, allowing the power plant to follow typical electricity usage.

Renewable Coal Replacement Strategies

Renewable coal replacement strategies can be divided into two categories: power plants and, what I am calling, power plant ensembles. The former are self-contained power plants that can duplicate the power output of coal plants while the latter are combinations of power plants or power plants with separate energy storage that can do the same.

Renewable Power Plants

1) Hydroelectric with year-round water supply – Hydroelectric plants can replace the function of coal-fired power if they are built in a location with sufficient water flow and vertical drop. Other environmental conditions include adequate rainfall year round or seasonal rainfall with adequate storage. The output of hydroelectric plants can fluctuate with seasonal and yearly rainfall so these plants are vulnerable to drought. In addition, dam-building unfortunately disrupts river environments so the demand for power needs to be balanced with other economic and environmental concerns. In the developed world, hydroelectric potential of larger rivers has already been exploited, but undeveloped smaller and middle sized rivers may offer opportunities for further new power generation. In the developing world there is still room for growth of hydroelectric, yet these projects will not keep up with electric demand in the most rapidly industrializing areas like China.

Strengths:

  • Mature technology
  • Accepted by power industry
  • Capable of baseload, load-following and peak load (i.e. dispatchable) production.
  • Smaller and midsize plants can be less disruptive of rivers and settlement, easier to permit and build.
  • Room for as much as two-fold growth in the developed world with smaller and midsize plants.
  • With dams represent a large energy store and are dispatchable.
  • Room for as much as ten fold growth in the developing world.
  • Affordable with state subsidy in dam building; dams sometimes run by government as a public good.

Challenges:

  • Limited by geography and rainfall
  • Potential insufficient to meet current worldwide power demand alone
  • Vulnerable to drought, climate change, and seasonal fluctuations in water flow
  • Large dam building disrupts river ecology and existing human settlement if within reservoir.
  • Large dams require lead-time of years to study, permit and build
  • Large dams are very capital intensive
  • Competes with other economic uses of river

2) Solar thermal electric with >16 hour Thermal Storage – The most mature technology in the area of newer renewable energy alternatives, solar thermal electric taps into the direct sun of deserts and dry Mediterranean climates. Sometimes called concentrating solar power or CSP, these plants use mirrors to concentrate the sun on a thermal fluid that transports heat either directly to generate electricity in a steam generator (similar to those in coal, gas or nuclear plants) or is stored in a tank for later use to generate electricity by the same method. These tanks can use water, a thermal oil, or molten salt (a mixture of melted ionic compounds [salts] that have favorable thermal properties) as the heat transfer fluid and heat storage medium. There are now several existing power plants in the Southwestern US and Spain with more planned. A small fraction (less than 2%) of the area of the world’s deserts (Sahara, Arabian, Kalahari, American Southwest, Mexican Sonoran, Atacama, Takla Makan in China, Australian Outback) would supply all of the world’s energy demand with sufficient storage and transmission infrastructure. While one US government-funded demonstration power plant in the 1980’s was able to produce power continuously for 7 days, current commercial designs are not explicitly designed with the excess storage and solar collectors and that allows continuous operation that would replace baseload power. Coal replacement plants will have adequate ratio of collectors to storage to turbine power rating throughout the year. During the winter solstice, all of these plants will produce as much as 40% less power than during the summer solstice, so design of a coal replacement plant will need to account for winter demand, or supplement winter production with other sources.

Strengths:

  • Rapidly maturing technology
  • Can re-use parts of power engineering knowledge base in turbine and power plant design
  • Intuitively understandable by lay people as a source of power (desert=sun=heat=steam=electricity)
  • Online for years in the American Southwest/demonstration of always-on capability in experimental setting
  • Plants could theoretically could exceed 85% capacity factor with sufficient sun, collector-to-turbine-power-rating ratio, and heat storage
  • Potential to meet all of world energy demand with low impact footprint
  • Solar energy approximately follows daily electric load with a few hours offset and can operate as a peaker plant with storage.
  • Theoretically plants could be built within a period of one to two years
  • Currently affordable for developed nations willing to pay premium for clean power

Challenges:

  • Currently more expensive than depreciated coal plants inclusive of transmission costs
  • Footprints of plants (though in remote locations) are larger than conventional power plants
  • Overlooked and underfunded for a couple decades.
  • Requires trans-regional cooperation between electricity retailers or national energy agencies to reach full potential
  • Requires building of new transmission infrastructure including long distance lines reaching areas distant from deserts.
  • Alternative power plant cooling that minimizes water use reduces plant efficiency

3) Enhanced Geothermal Systems (EGS) – Geothermal power can be divided approximately into two categories: traditional hydrothermal and EGS. Traditional hydrothermal uses natural steam and heat reservoirs and flow close to the surface but is only applicable in certain locations (parts of Western US, Iceland, Italy, Hawaii). EGS creates engineered geothermal wells by drilling deep in earth’s crust and creating a water flow circuit that collects and transports the deep heat to the surface and could create geothermal power plants in most areas of the globe. EGS is still in experimental stages but studies of heat content and flow indicate that it can eventually produce more than enough power for the world. Geothermal and EGS can produce baseload power as the flow of heat to the surface remains at a constant level, day and night once a well has been properly calibrated. Problems remain with engineering functional water flow channels at depths of 4 km and deeper with the goal of 10 km allowing for widespread commercialization. EGS will build on existing deep drilling technology from petroleum exploration and competes directly with oil exploration for drill rigs.

Strengths:

  • Power could be produced close to load centers
  • Builds on existing geothermal expertise
  • Builds on existing drilling expertise
  • Hydrothermal geothermal is a proven source of baseload power for over 100 years
  • Geothermal plants have a high capacity factor (>85%)
  • Potential to meet all world wide energy demand once fully developed
  • Provides a post-carbon role for petroleum industry

Challenges:

  • Still in experimental stages
  • Competes with oil exploration for drilling rigs
  • EGS wells and techniques need to be tailored to local geology
  • May not scale up as rapidly as demand for carbon-free power
  • No current existing EGS power plants online
  • In most locations, heat extraction over a period of decades will deplete stored heat at a rate that requires a couple centuries of replenishment to restore original rock temperature: power plants may need to be moved after several decades.

4) High Altitude Wind – More experimental than the foregoing, the winds in and around the jet streams of the northern and southern Hemispheres located between 30 and 60 degrees latitude at heights from 4 to 11 km have some of the highest power density of any renewable energy sources (over 10 kW/m^2 at 10km altitude). The winds at some of these altitudes blow consistently at varying speeds with some north-south movement of the jet streams themselves. Advocates of high altitude wind speak of capacity factors for wind turbines of varying designs in the range of 60 to 95% depending on location. Various designs have been proposed, some that use kites, some that use dirigibles, some carousels. Technical challenges include weatherproofing, lofting and tethering these turbines with light, high capacity conductors. Permitting and liability concerns may develop if these aerial plants are suspended over land and follow the stream as it wanders. Coordination with air traffic is also a must. Early experiments and prototypes might use the lower altitude high-speed winds of the Southern Hemisphere that at the surface of the Southern Ocean make up the “Roaring Forties”.

Strengths

  • High power density of winds lead to low potential costs (fewer power plants per unit area with more power)
  • Located at mid-latitudes where there are high population/ energy demand centers
  • Wind speeds have been continually documented by atmospheric research
  • If windspeeds are consistently above a certain minimum relative to a turbine’s power rating, can function as baseload power
  • Has the potential to meet all power demand

Challenges:

  • Still in experimental stages; a new technology
  • Energy production limited to latitudes greater than 30 degrees
  • Many competing and divergent designs
  • Field testing will require airspace permits
  • Lightweight high capacity conductors/tethers have yet to be invented
  • Conductors and mid-altitude turbines may need to resist lightning, violent weather.
  • Wind does not have constant velocity might not reliably function as baseload power
  • Highest velocity wind is at 35,000 ft./ 10 kilometers in height
  • Jetstream designs may compete with aviation for airspace
  • Exact ground footprint unknown

5) Ocean Thermal Energy Conversion (OTEC) – Uses differences in temperature of top layers of tropical oceans with the cold of the lower depths to generate electricity using a heat engine/turbine. Applicable in tropics where solar and wind energy flux is inconsistent or weak. OTEC is still in experimental stages. Extraction of volumes of cold water has unknown effects on geophysics of deeper cold layers of the ocean. Has not been the subject of a consistent level of funding. Cold water can be used to promote agriculture and supply air conditioning on tropical islands.

Strengths:

  • An energy source for tropical areas without consistent wind or sun.
  • Can function as baseload power
  • Cold water has additional economic uses in tropics
  • Can replace expensive diesel power generation on tropical islands

Challenges:

  • Still in experimental or early prototype stages
  • Commercial costs are unknown
  • Underfunded for many years
  • May have unknown effects on ocean environment including risk release of methane hydrates (strong GHGs) from deep ocean.
  • Rate of recovery of cold layers of ocean unknown

Power Plant Ensembles

Like a musical ensemble, an ensemble of power plants can coordinate across as many as thousands of miles if they are on the same transmission network and shape their output to create a joint output profile.

1) Continental Supergrid for Wind - Proposed by wind advocates in Europe and the US and the large utility American Electric Power in the US to balance wind variation across space. Foreseen as connecting conventional large wind turbines either offshore on onshore. Requires major transmission infrastructure and sophisticated grid management systems.

Strengths:

  • Uses mature technologies
  • Wind in favorable locations produces electricity at competitive costs
  • Taps into known resources
  • Distributes energy development and production through a number of regions
  • Has support of existing players in renewable energy and transmission
  • Has the potential to cover much or all of electric demand in the US and Western and Northern Europe

Challenges:

  • It is unknown whether combined wind energy in a geographical area can at all times cover electric demand; may require additional technologies to firm.
  • Requires complex cross-regional and cross-national coordination.
  • Transmission is expensive.
  • Selection of type of transmission (HVAC vs HVDC, above ground, underground) factors in a variety of political, technological and economic factors.
  • Not applicable as applicable where wind is scarce.

2) Regional or Continental Linkage of Wind with Hydroelectric/Pumped Storage – In both North America and Northern Europe, systems have been proposed or worked out where wind production can become firm (“firm” meaning that a utility can rely on it) when coordinated with hydroelectric production. With this coordination, hydroelectric plants reduce flow when wind is producing then increase flow when wind dies down; thus water builds up in the hydro reservoir while wind is available, saving it for when it is needed. Denmark currently has such an agreement with neighboring countries and there are proposals for a similar system in British Columbia for the Western US. Such a system requires spare capacity in hydroelectric reservoirs. Alternatively, wind can pump water into a pumped storage reservoir that then outputs power when requested by grid operators. (KEMA, a Netherlands-based international power consulting company has proposed an Energy Island concept that integrates wind with pumped storage in an offshore environment, thereby avoiding variations in rainfall.)

Strengths

  • Mature technologies.
  • Currently economic energy production technologies.
  • Already used successfully in Denmark/ proposals for British Columbia.
  • Could supply baseload, load-following or peak power.

Challenges

  • Requires collocation or coordination of two geographically limited resources: wind and hydroelectric to connected load centers.
  • Requires large excess capacity of hydroelectric reservoirs.
  • Requires regional or continental coordination between business entities.
  • Vulnerable to a coincidence of wind and rain droughts.

3) Solar Thermal Electric (CSP) plus Storage with Wind – Just as wind can help extend the use of hydroelectric resources, wind can also help extend the use of stored heat in a solar thermal electric plant. The dispatchability of solar thermal electric coordinated with a wind resource in the same grid region allows for a smoothed power output of wind and an extension of heat reserves during the night and cloudy weather. To be able to create an ultra-high capacity factor baseload power alternative, the solar thermal plant should probably have in excess of 36 hours heat storage to produce continuously through two cloudy days with available wind. The fact that wind tends to blow during the night respresents an additional complementarity between solar thermal and wind. A similar ensemble between solar thermal and hydroelectric or a triangulation between solar thermal, hydroelectric/pumped storage and wind are all possible.

Strengths

  • Offset between timing of wind and sun.
  • Both mature or rapidly maturing technologies.
  • Can cover baseload, follow load or peak.
  • Wind brings down cost of and extends thermal storage.
  • Both resources with sufficient transmission can fulfill world energy demand.

Challenges

  • Bringing down cost of STE/CSP and mass thermal storage.
  • Collocation of wind and solar thermal in same grid region.
  • Coordination between wind and solar generators.

Sending Coal to the Sidelines

There are now viable renewable alternatives to coal and more will be available soon with technological improvements and cost reductions in any one of these technologies. While technological improvements can have a catalytic effect, popular and political will in favor of renewable solutions will help speed getting current and near-term technologies online in the next several years. A commitment to sustainability within the power industry, which has been as addicted as we all have been to fossil and unsustainable fuels, will be an additional factor that will speed the transition to renewable fuels. The coal replacement renewable alternatives require reliance on both the existing knowledge base of the power industry as well as some out-of-the-box thinking.

One can imagine a number of scenarios that can start today, where renewable power will replace the most toxic power plants within a period of years. Regions that have a natural advantage in this endeavor are those near deserts or with substantial hydroelectric capacity. As of today, it is possible to build or plan the development of these resources. Connection to wind resources will enable a more rapid transition to renewable baseload or a majority renewable generation portfolio. Iceland with its exceptional geothermal and hydroelectric is already close to creating an all-renewable energy system.

The short-sighted practice of using valuable and exhaustible fossil fuels to generate electricity on a daily basis will give way to a more suitable use of these power plants, as back-up power. Coal and natural gas will continue to have value in their place on the sidelines as daily electricity demand is met largely by renewable generators. With such a system, we will maintain the reliability of electricity delivery while taking steps towards a cleaner, healthier, more sustainable future.
