    Governments always subsidize energy -- because energy is vital to governments.

    To accuse a government of picking winners or succumbing to special interests because it supports the energy that will make the country go is as sensible as accusing a car driver of picking a winner or succumbing to a special interest for buying gas.

    As detailed in the report below, the coal industry had no problem with this principle when it was the darling of the British government in the 19th century. The oil industry had no problem with it when it was the United States' golden child in the first half of the 20th century. The nuclear industry was pleased to be the chosen one from the 1960s to the 1980s.

    But when the nations of the world responded to the threat of greenhouse gas emissions or nuclear waste by supporting renewables, the vested interests began throwing fits about energy subsidies.

    Do renewables get an inequitable slice of the federal pie? It depends: The U.S. Energy Information Administration (EIA) calculates subsidies per year for each generation source. This makes it possible for the renewables’ subsidies to be characterized by opponents as radically disproportionate to the BTUs for which they account. However, this is not necessarily the most accurate way to assess subsidy dollars.

    As the EIA itself has acknowledged, electricity generation technologies that have been supported for decades and that are now mature and self-supporting do not need or get as much support as renewables, which are less mature and have only recently become more highly valued and subsidized.

    But the mature industries that emerged in the past would not be so successful today if they had not been given support when it was needed.

    An example: A coal plant built in 1965 has been the beneficiary of subsidies for 45 years. A wind farm built in 2008 is collecting the bulk of its support now but will get no more federal money after 2017. Yet, by the EIA calculation, the wind farm is at present getting the bulk of the federal dollars.

    With the benefit of historical perspective, it becomes clear that the subsidies now flowing to renewables mean federal lawmakers intend to prioritize renewables in the same way other electricity sources were prioritized in past decades. Similar support for renewables is now emerging even more strongly at state and local levels in the U.S. and in other governments all over the world.

    More importantly, subsidies to renewables imply that governments all over the world believe them to be a more important and/or better value proposition going forward and they realize they must put a higher emphasis on developing the energy of the 21st century.

    This is how governments always use energy subsidies, as the historical perspective detailed in the study below demonstrates.

    The coal industry would not be what it is without the railroad system it was given a century and a half ago.

    The U.S. oil industry would have strangled by its own terminal greediness had Congress not provided it with the Oil Depletion Allowance and Golden Gimmick tax breaks in the middle of the last century.

    Nobody would have built nuclear plants in the 1970s if the Price-Anderson Act hadn’t indemnified the industry against its occasional catastrophes.

    And renewables, in partnership with efficiency and storage technologies, will not reach scale or replace fossil fuels if not provided with reasonable subsidies.

    What Would Jefferson Do? The Historical Role of Federal Subsidies in Shaping America’s Energy Future
    Nancy Pfund and Ben Healy, September 2011 (DBL Investors/Double Bottom Line Venture Capital)

    “Some argue that the consumer can purchase warmth or work or mobility at less cost
    by means of coal or oil or nuclear energy than by means of sunshine or wind or
    biomass. The argument concludes that this fact, in and of itself, relegates renewable
    energy resources to a small place in the national energy budget. The argument
    would be valid if energy prices were set in perfectly competitive markets. They are
    not. The costs of energy production have been underwritten unevenly among
    energy resources by the Federal Government.” …August 1981 report of the DOE Battelle Pacific Northwest National Laboratory

    Executive Summary

    This paper frames the ongoing debate about the appropriate size and scope of federal subsidies to the energy sector within the rich historical context of U.S. energy transitions, in order to help illuminate how current energy subsidies compare to past government support for the sector. From land grants for timber and coal in the 1800s to tax expenditures for oil and gas in the early 20th century, from federal investment in hydroelectric power to research and development funding for nuclear energy and today’s incentives for alternative energy sources, America’s support for energy innovation has helped drive our country’s growth for more than 200 years.

    click to enlarge

    Using data culled from the academic literature, government documents, and NGO sources, in this paper we examine the extent of federal support (as well as support from the various states in pre-Civil War America) for emerging energy technologies in their early days. We then analyze discrete periods in history when the federal government enacted specific subsidies. While other scholars have suggested that the scope of earlier subsidies was quite large, we are—as far as we know—the first to quantify exactly how the current federal commitment to renewables compares to support for earlier energy transitions. Our findings suggest that current renewable energy subsidies do not constitute an over-subsidized outlier when compared to the historical norm for emerging sources of energy. For example:

    - As a percentage of inflation-adjusted federal spending, nuclear subsidies accounted for more than 1% of the federal budget over their first 15 years, and oil and gas subsidies made up half a percent of the total budget, while renewables have constituted only about a tenth of a percent. That is to say, the federal commitment to O&G was five times greater than the federal commitment to renewables during the first 15 years of each subsidies’ life, and it was more than 10 times greater for nuclear.

    - In inflation-adjusted dollars, nuclear spending averaged $3.3 billion over the first 15 years of subsidy life, and O&G subsidies averaged $1.8 billion, while renewables averaged less than $0.4 billion.

    The charts below clearly demonstrate that federal incentives for early fossil fuel production and the nascent nuclear industry were much more robust than the support provided to renewables today.

    Over the course of decades, contentious debates have raged in Washington, DC about the appropriate size and scope of federal subsidies to the energy sector, including support for both traditional fossil fuel industries and the emerging renewable energy sector. Certainly, a quick survey of existing subsidies demonstrates that critics have plenty of legitimate reasons to complain. Take the capital gains treatment of royalties on coal as an example. This subsidy allows owners of coal mining rights to reclassify income traditionally subject to the income tax as royalty payments, thereby allowing owners to pay a reduced tax rate:

    This subsidy totaled well over $1.3 billion in government tax expenditures from 2000 – 2009…

    click to enlarge

    In 1950 and 1951, Congress increased a number of taxes to pay for the United States’ entry into the Korean War. With prevailing 1951 marginal income tax rates ranging up to a high of 91 percent and capital gains tax rates at 25 percent regardless of income, the reclassification was primarily adopted to insulate certain owners of coal mining rights from high marginal income tax rates … thus encouraging additional production. Since then, both income and capital gains tax rates for individuals have fallen, and the capital gains tax rate for individual owners currently stands at 15 percent. However, the credit is still available to members of the coal industry.

    True, this Korean War-era tax break seems grossly out of place in the 21st century, but not all subsidies are created equal. Historically, policymakers have justified intervention in energy markets “1) to promote a new technology during the early developmental stages and 2) to pay the difference between the value of an activity to the private sector and its value to the public sector.”2 Thus, it is worth evaluating our current energy subsidies through a longer historical lens, so that we can better understand how current incentives compare to past government support for the energy sector.

    We can read the history of the United States—our country’s geographic and economic expansion—through the history of our energy production and consumption. Through war and peace, through westward expansion and our rise to economic and military superpower status, we find that energy transitions fueled it all. Wood and small hydro powered our country’s early, rural days. As cities expanded, railroads crisscrossed the nation, and the Industrial Revolution took hold, coal dominated. With the invention and improvement of the internal combustion engine, oil catapulted into our preeminent fuel. Large hydro became a reality thanks to Depression-era initiatives that have continued to drive economic development programs across the country decades later, followed by nuclear power on the heels of World War II. And today, in pursuit of greater energy security, enhanced environmental quality and economic growth on a globalized playing field, renewable energy sources are transitioning from the margins to the mainstream. As the chart below starkly illuminates, our wealth and our energy usage are intimately intertwined.

    Energy innovation has driven America’s growth since before the 13 colonies came together to form the United States, and government support has driven that innovation for nearly as long. In this paper, we identify specific government interventions in the energy sector during moments of transition, and we attempt to quantify that support in order to compare it to current support for emerging renewable sources of energy. Although most of our quantitative analysis focuses on federal support, it is important to note that states have also contributed to the American energy narrative throughout our history, from the support of coal in the 19th century to incentives for renewable energy production 200 years later, and we will not ignore the role of the various states in the discussion that follows.

    click to enlarge

    Overall, what we find, in contrast to much of today’s headline-grabbing rhetoric, is that today’s government incentives for renewable energy pale in comparison to the kind of support afforded emerging fuels during previous energy transitions.

    Look back to the 1700s: From Battelle National Lab – “The first recorded commercial coal transaction in the United States was a 32-ton shipment from the James River district in Virginia to New York in 1758.”

    …Into the 1800s: From Stanford’s Center for International Security and Cooperation – “As a pamphleteer wrote in 1860, a year after Uncle Billy Smith struck oil at Oil Creek in Titusville, Pennsylvania, ‘Rock oil emits a dainty light, the brightest and yet the cheapest in the world; a light fit for Kings and Royalists and not unsuitable for Republicans and Democrats.’”…

    From the Renewable Energy Policy Project – “The first attempt to transport natural gas on a large scale was in Rochester, New York in 1870. A 25-mile line was constructed of hollowed pine logs. It was a failure.”

    …Through the 1900s: From Greenpeace – “In December, 1953, President Eisenhower inaugurated an ‘Atoms for Peace’ [nuclear energy] program that…would ultimately swallow the lion’s share of federal dollars for energy research.

    Conclusion–In Energy We Trust

    In closing, we present the two images below, the first a 1962 Life magazine advertisement from Humble Oil (now Exxon Mobil) and the second a graphical representation of America’s current dependence on foreign sources of energy.

    Together, these two images demonstrate the fact—more clearly than we ever could in words—that America’s energy needs and priorities have changed over time, and that they will continue to evolve going forward, driven by economics, environmental concerns, and security issues. Throughout our history, energy incentives have helped drive critical innovation, speed U.S. economic transitions, and helped shape our national character. Today, as we seek to move towards a more independent and clean energy future, the truth is that renewables—from a historical perspective—are if anything under-subsidized. This weak support is inconsistent with our nation’s own historical energy narrative, which suggests:

    click to enlarge

    Today’s market for cheap power results in part from substantial investment by the federal government in innovative technology.

    It takes a substantial amount of money, invested over several years, to bring an electricity generation technology to maturity.

    Although energy subsidies can and do serve many policy purposes, the most basic relate to furthering the development and commercialization of technologies deemed to be in the public interest.

    We titled this paper, “What Would Jefferson Do?” We believe that the answer to that question is now clear. He would do what our country has always done—support emerging energy technologies—to drive innovation, create jobs, protect our environment, enhance our national security in a time of rapid change, and to further a distinctly American way of life in which resources once thought to be endless are replaced by ones that actually are.

    Tracking the Sun IV; An Historical Summary of the Installed Cost of Photovoltaics in the United States from 1998 to 2010
    Galen Barbose, Naïm Darghouth and Ryan Wiser, September 2011 ()

    Executive Summary

    As the deployment of grid-connected solar photovoltaic (PV) systems has increased, so too has the desire to track the installed cost of these systems over time and by location, customer type, system characteristics, and component. This report helps to fill this need by summarizing trends in the installed cost of grid-connected PV systems in the United States from 1998 through 2010, with preliminary data for 2011, and includes, for the first time, installed cost trends for utility-sector PV. The analysis is based on installed cost data for approximately 116,500 behind-the-meter (i.e., residential and commercial) and utility-sector PV systems, totaling 1,685 megawatts (MW) and representing 79% of all grid-connected PV capacity installed in the United States through 2010…

    click to enlarge

    It is essential to note at the outset the limitations inherent in the data presented within this report. First, the cost data are historical, focusing primarily on projects installed through the end of 2010, and therefore do not reflect the cost of projects installed more recently (with the exception of a limited set of results presented for behind-the-meter projects installed in the first half of 2011); nor are the data presented here representative of costs that are currently being quoted for prospective projects to be installed at a later date. For this reason and others (see Text Box 1 within the main body of the report), the results presented herein likely differ from current PV cost benchmarks. Second, this report focuses on the up-front cost to install PV systems; as such, it does not capture trends associated with PV performance or other factors that affect the levelized cost of electricity (LCOE) for PV. Third, the utility-sector PV cost data presented in this report are based on a small sample size (reflecting the small number of utility-sector systems installed through 2010), and include a number of relatively small projects and “one-off” projects with atypical project characteristics. Fourth, the data sample includes many third party-owned projects where either the system is leased to the site-host or the generation output is sold to the site-host under a power purchase agreement. The installed cost data reported for these projects are somewhat ambiguous – in some cases representing the actual cost to install the project, while in other cases representing the assessed “fair market value” of the project.2 As shown within the report, however, the available data suggest that any bias in the installed cost data reported for third party- owned systems is not likely to have significantly skewed the overall cost trends presented here.

    click to enlarge

    The report separately describes cost trends for behind-the-meter PV systems and utility- sector systems. Key findings regarding the installed cost of behind-the-meter PV systems are as follows:

    The capacity-weighted average installed cost of all behind-the-meter systems installed in 2010 – in terms of real 2010 dollars per installed watt (DC-STC)3 and prior to receipt of any direct financial incentives or tax credits – was $6.2/Watt, and was $1.3/W (17%) below the average for systems installed in 2009.

    Partial data for the first six months of 2011 indicates that installed costs have continued to rapidly decline, with the capacity-weighted average installed cost of projects funded through the California Solar Initiative falling by an additional $0.7/W during the first half of 2011, amounting to an 11% drop from average costs in 2010.

    click to enlarge

    The recent decline in installed costs is, in large part, attributable to falling wholesale module prices, which fell by $0.9/W from 2008 to 2009, by $0.5/W from 2009 to 2010, and which have fallen further still in 2011 (based on Navigant Consulting’s Global Power Module Price Index). The fact that average installed costs remained flat from 2008 to 2009, before dropping significantly in 2010, illustrates that movements in global wholesale module prices do not necessarily translate into an immediate, commensurate change in the cost borne by the final system owner; a time lag is apparent.

    The recent decline in installed costs is also attributable to falling non-module costs. Based on component-level cost data reported by installers to PV incentive programs, non-module and non-inverter costs (which may include such items as mounting hardware, labor, permitting and fees, shipping, overhead, taxes, and installer profit) fell by roughly $0.6/W from 2009 to 2010.

    PV installed costs exhibit significant economies of scale, with systems ≤2 kW completed in 2010 averaging $9.8/W, while >1,000 kW behind-the-meter systems averaged $5.2/W (or about 47% less). The cost of utility-sector systems was even lower, as discussed further below. These economies of scale partially explain the long-term decline in average installed costs, as the size distribution of PV systems has shifted towards larger systems over time.

    click to enlarge

    Large systems exhibited the greatest year-over-year cost declines from 2009 to 2010. For example, the average installed cost fell by $1.9/W (26%) for behind-the-meter systems in the >500 kW size range, but fell by a lower $0.9/W (11%) for ≤5 kW systems.

    The growing prevalence of third party owned PV systems has introduced some distortion into the underlying cost trends, but at least at an aggregate sample-wide level, the magnitude of the distortion is likely to be relatively modest. Among systems of all sizes installed in 2010, the capacity-weighted average installed cost of third party owned systems was $0.3/W higher than for customer-owned systems, though the differences are somewhat larger when comparing within specific system size categories.

    Average installed costs vary widely across states; among ≤10 kW systems completed in 2010, average costs range from a low of $6.3/W in New Hampshire to a high of $8.4/W in Utah. The country’s largest state PV markets, California and New Jersey, were near the center of this range, suggesting that, in addition to absolute market size, other state and local factors (e.g., permitting requirements, labor rates, the extent of third party ownership, and sales tax exemptions) also strongly influence installed costs.

    click to enlarge

    International experience suggests that greater near-term cost reductions in the United States are possible, as the average installed cost of 3-5 kW residential PV installations in 2010 (excluding sales/value-added tax) was significantly lower in Germany ($4.2/W) than in the United States ($6.9/W), where cumulative grid-connected PV capacity in the two countries through 2010 totaled roughly 17,000 MW and 2,100 MW, respectively.

    The new construction market offers cost advantages for small residential PV systems. Among 2-3 kW residential systems (the size range typical for residential new construction) installed in 2010 and funded through California’s incentive programs, new construction systems cost $0.7/W less, on average, than comparably sized residential retrofit systems (or $1.5/W less if comparing only rack-mounted systems).

    Systems with crystalline (multi- or mono-crystalline) modules had lower average installed costs than those with thin-film (amorphous silicon or non-silicon) modules, when focusing on <100 kW systems installed in 2010, but average installed costs were nearly identical for crystalline and thin-film systems within the >100 kW size range.

    As to be expected, systems with tracking equipment had higher installed costs than fixed-tilt systems, with a difference of $1.0/W in average installed costs for 10-100 kW systems installed in 2010 (insufficient data were available for larger system sizes).

    The drop in installed costs in 2010 was partially offset by falling incentives. State/utility cash incentives continued their historical decline, with average residential incentives falling by $0.5/W to $1.6/W and average commercial incentives falling by $0.3/W to $1.8/W (all on a pre-tax basis).4 The average dollar-per-watt value of the federal investment tax credit (ITC) or Treasury cash grant in lieu of the ITC also fell in 2010, due to the decline in installed costs.

    The capacity-weighted average net installed cost faced by PV system owners – that is, installed cost minus the combined after-tax value of state/utility cash incentives, the federal ITC (or Treasury grant), and any available state ITCs – stood at $3.6/W for residential PV and $3.0/W for commercial PV in 2010, in both cases an historic low.

    This report separately summarizes installed cost data for utility-sector PV projects, but these data must be interpreted with a certain degree of caution. First, the sample size is small (31 projects in total, including 20 projects installed in 2010), and includes a number of small wholesale distributed generation projects as well as a number of “one-off” projects with atypical project characteristics. The cost of these small or otherwise atypical projects is expected to be higher than the cost of many of the larger utility-scale PV projects currently under development. Second, the installed cost of any individual utility-sector project may reflect component pricing one or even two years prior to project completion, and therefore the cost of the utility-sector projects within the data sample may not fully capture the steep decline in module prices that occurred over the study period. With these important caveats in mind, several key trends for utility-sector PV systems emerge from our analysis:

    The installed cost of utility-sector systems varies significantly across projects. Among the 20 utility-sector projects in the data sample completed in 2010, installed costs ranged from $2.9/W to $7.4/W, reflecting the wide variation in project size (from less than 1 MW to 34 MW), differences in system configurations (e.g., fixed-tilt vs. tracking and thin-film vs. crystalline modules), and the unique characteristics of individual projects.

    Current cost benchmarks for utility-sector PV are generally at the low-end of the range exhibited by the 2010 projects in the data sample, with various entities estimating an installed cost of $3.8/W to $4.4/W, depending on system size and configuration for utility sector systems installed at the end of 2010 or beginning of 2011.

    The installed cost range of utility-sector systems in the data sample declines with system size, consistent with expected economies of scale. For example, among fixed-tilt, crystalline systems installed over the 2008-2010 period (we include a broader range of years here in order to increase the sample size), costs ranged from $3.7-$5.6/W for the five 5-20 MW systems, compared to $4.7-$6.3/W for the three <1 MW systems. Similarly, among thin film systems, the installed cost of the two >20 MW projects completed in 2008-2010 ranged from $2.4-$2.9/W, compared to $4.4-$5.1/W for the two <1 MW projects.

    Installed costs are lowest for thin-film systems and highest for crystalline systems with tracking. Among >5 MW systems installed from 2008-2010 (we again include a broader range of years in order to increase the sample size), installed costs ranged from $2.4-3.9/W for the five thin-film systems, compared to $3.7-$5.6/W for the five crystalline systems without tracking and $4.2-$6.2/W for the four crystalline systems with tracking. To more comprehensively compare the cost of these alternate system configurations, one would need to also consider differences in performance and the related impact on the LCOE.

    The wide distribution in the installed cost of utility-sector systems in the data sample is partially attributable to the presence of systems with unique characteristics that increase costs. For example, among the 2010 installations in the data sample are a 10 MW tracking system built on an urban brownfield site ($6.2/W), an 11 MW fixed-axis system built to withstand hurricane winds ($5.6/W), and a collection of panels mounted on thousands of individual utility distribution poles totaling 14.6 MW ($7.4/W).

    Conclusions and Policy Implications

    The number of PV systems installed in the United States has grown at a rapid pace in recent years, driven in large measure by government incentives. Given the relatively high historical cost of PV, a key goal of these policies has been to encourage cost reductions over time. Available evidence confirms that the installed cost of PV systems has declined substantially since 1998, though both the pace and source of those cost reductions have varied over time. Prior to 2005, installed cost reductions were associated primarily with a decline in non-module costs. Starting in 2005, however, cost reductions began to stall, as the supply-chain and delivery infrastructure struggled to keep pace with rapidly expanding global demand. Starting in 2008, global wholesale module prices began a steep downward trajectory. Those reductions in module prices began to drive the average installed cost of PV systems installed in the United States significantly lower in 2010, when average installed costs fell by 17%.

    In addition, average non-module costs also fell significantly in 2010, after several years of apparent stagnation. Trends in non-module costs may be particularly relevant in gauging the impact of state and utility PV deployment programs. Unlike module prices, which are primarily established through global markets, non-module costs consist of a variety of cost components that may be more readily affected by local programs – including deployment programs aimed at increasing demand (and thereby increasing competition and efficiency among installers) as well as more-targeted efforts, such as training and education programs. Both the long-term and more recent reductions in non-module costs suggests that PV deployment policies have achieved some success in fostering competition within the industry and spurring improvements in the cost structure and efficiency of the PV delivery infrastructure.

    Preliminary cost data for the first half of 2011, as well as current cost benchmarks published by a variety of other entities, indicate that installed costs have continued to decline. Notwithstanding this success, further cost reductions will be necessary if the U.S. PV industry is to continue its expansion, given the expectation that PV incentive programs will also continue to ratchet down financial support. Lower average installed costs in Germany suggest that deeper near-term cost reductions in United States are, in fact, possible and may accompany increased market scale. It is also evident, however, that market size alone is insufficient to fully capture potential near-term cost reductions, as suggested by the fact that the lowest-cost state markets in the United States are relatively small PV markets. Targeted policies aimed at specific cost barriers (for example, permitting and interconnection costs), in concert with basic and applied research and development, may therefore be required in order to sustain the pace of installed cost reductions on a long-term basis.

    Finally, installed costs vary substantially across system sizes, market segments, technology types, and applications. Policymakers may wish to evaluate whether differential levels of financial support are therefore warranted (e.g., to avoid over-subsidizing more cost-competitive installations while providing sufficient support for promising but less mature technologies and applications).


    Utility merger could end up helping 1st offshore wind farm sell its power, get financing

    "…The nation's first offshore wind farm…Cape Wind…needs to attract big power customers to obtain the financing to fully build out its 130-turbine project in Nantucket Sound…[because] the utility NStar has taken a tepid public stance on Cape Wind…[but a] pending merger between NStar and Northeast Utilities has become a possible pressure point to get NStar to buy Cape Wind power.

    "Since the merger was announced last year, regulators added a requirement that such deals must advance the state's clean energy goals, which include developing offshore wind.

    With Congress likely to cut federal spending and private funds still awaiting market certainty, New Energy might run out of support but for a surprising benefactor, the U.S. Department of Defense (DoD).

    As detailed in the report below, DoD spending for renewables and efficiency went from $400 million in 2006 to $1.2 billion in 2009, a jump of 300 percent.

    Because military leaders believe investments in New Energy, which began during the George W. Bush administration, preserve lives on the battlefield, protect the nation’s security and save taxpayer money, current plans call for an increase in the DoD’s spending on renewables to $3 billion by 2015 and to over $10 billion per year by 2030.

    Besides its profound impact on military operations, this promises a major infusion of funding just when New Energy needs it most.

    New Energy will also benefit the military, as well as the U.S. economy, by generating jobs. A recent estimate put military veterans’ jobless rate at an unacceptable 30 percent, costing the military $882 million yearly in unemployment benefits. This could grow significantly as some 200,000 active duty personnel leave the services each year over the next quarter century.

    Meanwhile, job opportunities in New Energy and Energy Efficiency are growing twice as fast jobs in the economy as a whole. The U.S. solar industry saw 6.8 percent job growth last year. And a recent report estimated U.S. utilities will lose some 200,000 workers to retirement by 2014. Military personnel with service experience in New Energy and grid technologies should be among the best candidates applying for such jobs.

    Military spending in support of energy is not new. Winston Churchill’s decision in 1911 to move the British Navy, then the world’s then most dominant military force, from coal to oil changed the world’s energy marketplace. The emerging trend in DoD spending on New Energy is an equally historic marker.

    From Barracks to the Battlefield; Clean Energy Innovation and America’s Armed Forces
    September 21, 2011 (The Pew Project on National Security, Energy and Climate)

    Executive Summary

    Throughout its history, the U.S. Department of Defense (DoD) has invested in new ways of harnessing energy to enhance the strength, speed, range and power of the armed forces. Until recently, the U.S. military’s innovation agenda has not placed a high premium on energy efficiency and new sources of energy and fuels. But the department’s experience conducting wars in Iraq and Afghanistan and the rise of new global threats and challenges have caused DoD to rethink its strategic energy posture. Special emphasis has been placed on reducing battlefield fuel demand and securing reliable, renewable energy supplies for combat and installation operations.

    DoD’s major energy challenges include risks associated with transporting liquid fuels to and on the battlefield; growing oil price volatility; the impact of fuel dependence on operational effectiveness; the fragility of energy supplies for forces that must have assured power 24 hours a day; and energy laws and mandates the department must comply with.

    This report details how energy innovation and clean energy can help DoD respond to these energy challenges. It also explores ways in which DoD’s commitment to energy transformation is contributing to development of new energy technologies that can serve American consumers and commercial interests alike. Special attention is given to priority DoD initiatives in key areas of the world’s burgeoning and competitive clean energy sector: vehicle efficiency, advanced biofuels, and energy efficient and renewable energy technologies for buildings.

    How Innovation Can Help Address DoD Energy Challenges

    The emergence of the clean energy sector and increasingly competitive alternative energy sources presents DoD with opportunities for saving lives and money in the years ahead. Energy efficiency measures help reduce fuel demand and operational risk while enhancing combat effectiveness. For example, DoD insulated 9 million square feet of temporary structures, reducing energy consumption by 77,000 gallons per day…Alternative fuels and renewable energy sources can be domestically produced (and locally sourced around the world) to enhance the security of energy supplies. Similarly, microgrids and “smart” energy technologies help protect DoD installations from commercial power outages.

    New energy technologies also help shield the department from oil price volatility. In contrast to oil prices, the cost of renewable energy has been declining rapidly in recent years. The cost of solar panels, for example, has decreased by more than 60 percent since 2009…

    How DoD Can Help Advance Energy Innovation

    In recent decades, DoD technology development efforts have supported commercial development of computers, the Internet, the Global Positioning System, semiconductors and many more innovations. DoD has a broad range of strengths that can help accelerate clean energy technology development and commercial maturity. These include an established research and development infrastructure, ability to grow demonstration projects to scale, significant purchasing power and the necessary culture and management infrastructure necessary to foster innovation.

    In recent years, DoD has begun to harness these capabilities in service of energy technology innovation. Its budget for energy security initiatives has risen from $400 million to $1.2 billion in the past four years…and market experts project steadily increased expenditures for energy innovation activities in the coming years. Pike Research estimates that DoD investments in advanced energy technologies will reach $10 billion a year by 2030…

    DoD Progress on Key Technologies

    While the Department of Defense is exploring a wide range of innovations to enhance energy security and improve operational effectiveness, its efforts in three areas stand out: 1) developing of more efficient vehicles to reduce battlefield fuel demand;
    2) harnessing advanced biofuels as an alternative to petroleum fuels; and
    3) deploying energy efficient and renewable energy technologies at fixed and forward

    More Efficient Vehicles

    Energy efficiency across DoD’s large fleet of airplanes, ships and ground vehicles represents the cheapest, fastest and most effective means of reducing fuel consumption and addressing operational risk to soldiers, price volatility, supply security and mission success. Liquid petroleum fuels account for approximately three-quarters of DoD’s annual energy consumption and more than $11 billion of its annual energy bill. The department’s efforts to reduce its dependence on petroleum are taking shape through research and development, demonstration projects, and deployment of clean vehicle technologies in air, land and sea fleets.


    Improving the efficiency of the military aviation fleet is the most promising opportunity for reducing DoD fuel consumption. A leading efficiency expert has estimated that a 35 percent efficiency upgrade in defense aircraft would offset as much fuel as is currently used by all DoD facilities and ground and marine vehicles combined…Developing new airplanes with more efficient off-the-shelf technologies and accelerating aircraft replacement will reduce petroleum use in the near term, but development and adoption of new technologies will be critical as the Air Force seeks to reduce the amount of fuel burned by legacy aircraft (those currently in use) by 20 percent by 2030…In addition to its own aircraft fuel efficiency improvements, the Navy is also working to reduce fuel consumption by mandating greater use of aircraft training simulators…Overall DoD spending to harness clean energy technologies in the air, at sea and on the ground is projected to increase to $2.25 billion annually by 2015…

    Electric Ground Vehicles

    The department is also advancing electric vehicle technologies. By focusing on improvements in advanced combustion engines and transmissions, lightweight materials, thermal management and hybrid propulsion systems, DoD hopes to meet the requirements of Executive Order 13423, which mandates a 30 percent reduction in non-tactical fleet fossil fuel use by 2020.

    In June 2011, the department issued a request for information from electric vehicle manufacturers, battery manufacturers, suppliers, financing corporations and other stakeholders on equipment costs, availability of technologies, financing options and other innovative proposals that would allow DoD to deploy electric vehicles at a cost that is competitive with internal combustion engine vehicles. With more than 190,000 non-tactical vehicles, the deployment of medium and heavy duty electric vehicles in military fleets could be significant in just a few years, assuming that procurement can be achieved at competitive prices.


    With a goal of increasing efficiency and reducing fuel consumption on ships by 15 percent between 2010 and 2020, the Navy is testing and advancing new technologies in its operational vessels.10 To achieve its fuel reduction goal, the Navy is investing $91 million in fiscal year 2012 to develop more efficient materials and power systems for engines, advanced materials for propellers and water jets, and systems that allow ship hulls to eliminate biological growth that can reduce efficiency…By installing stern flaps, which reduce drag and the energy required to propel a ship through the water, the Navy has already generated annual fuel savings of up to $450,000 per ship.

    The Navy has also made progress on hybrid systems for ships. The USS Makin Island was commissioned in 2009 with a hybrid electric propulsion system that will save more than $250 million in fuel costs over the life of the ship…Looking forward, a hybrid electric drive system will be tested and installed as a proof of concept on the USS Truxtun. The Navy estimates successful testing will result in fuel savings of up to 8,500 barrels per year.

    Advanced Biofuels

    Even with sustained improvements in vehicle efficiency, the department will rely for the foreseeable future on liquid fuels as its primary energy source. Therefore, DoD is taking prudent steps to harness advanced biofuels. In fact, the various service branches have set ambitious goals:

    • The Air Force wants to use alternative aviation fuels for 50 percent of its domestic aviation needs by 2016.

    • The Navy aims to sail a “Great Green Fleet” and along with the Marines plans to use alternative energy sources to meet 50 percent of its energy requirements across operational platforms by 2020.

    • The Army seeks to harness alternative fuels to power its vehicle fleet and meet the EO 13423 goal of increasing non-petroleum fuel use by 10 percent annually in non-tactical vehicles.

    To reach these goals, the armed services are considering a variety of alternatives with potential for fulfilling military requirements. DoD is moving forward prudently to ensure that advanced biofuels can be developed and produced in a manner that is cost-competitive, compatible with existing military hardware, domestically available at the scale DoD needs, and environmentally sound.

    The Defense Advanced Research Projects Agency (DARPA) is exploring a variety of biofuel technologies on behalf of the armed services, including production of cost competitive algal-based biofuels within five years.

    Testing and Certification

    On March 25, 2010, the Air Force successfully conducted the first flight test of an aircraft powered by a 50-50 camelina-based biofuel blend. As of mid-2011, 99 percent of the Air Force fleet has been certified to fly on biofuel blends.15 The Air Force expects to complete all flight testing by February 2012 and all certifications by December 2012.

    The Navy also is actively engaged in testing and certifying advanced biofuels for planes and ships—flying the “Green Hornet” on a camelina-based jet fuel and floating Riverine Command Boat-Experimental (RCB-X) on a biofuel derived from algae…


    The Navy is planning to demonstrate a carrier strike group powered solely by alternative fuels in 2012. Dubbed the Great Green Fleet, the ships and planes are expected to conduct an extended mission in 2016, and all energy provided to operational platforms is to be 50 percent alternative by 2020.

    Cooperation With Industry

    Cognizant of the extensive commercial interest in development of advanced biofuels, DoD is working closely with domestic agriculture, aviation and other transportation industries.

    In August 2011, President Barack Obama announced that the U.S. Navy, along with the Departments of Energy and Agriculture, would invest up to $510 million to co-finance construction or retrofit plants and refineries capable of producing significant quantities of advanced biofuels over the next three years…The Navy, DoE and USDA issued a request for information (RFI) to the industry about ideas for how to establish a commercially viable drop-in biofuels industry…This initiative will help reduce the cost of advanced biofuels, ensure that supplies of these new fuels are available for military testing and use, and spur job creation and economic opportunities in rural America.

    Clean Energy at DoD Bases

    The Department of Defense manages more than 500,000 buildings and structures at 500 major installations around the world. The building space under DoD management totals about 2.2 billion square feet, three times the square footage operated by Wal-Mart and more than 10 times that of the U.S. government’s General Services Administration…In theater, DoD also runs a number of forward operating bases that require energy to power electronics, provide lighting, and heat or cool air and water.

    Across its fixed building stock and forward operating bases, DoD has ample opportunities to save energy and deploy new alternative energy sources. Since 1985, DOD has reduced its facility energy consumption by more than 30 percent…Over the past decade, its Energy Conservation Investment Program (ECIP) financed more than $440 million worth of energy-saving measures at installations. In addition, from 1999 to 2007, more than $3.8 billion worth of energy efficiency improvements at DoD facilities were financed through innovative third party finance mechanisms…Including third-party financing, DoD expenditures in fiscal year 2010 alone totaled $1.09 billion for energy and water efficiency and renewable energy…

    Recognizing the benefits of actively managing energy use at its facilities, DoD is pursuing energy efficiency, renewable energy, and energy storage measures at fixed and forward bases.

    Energy Efficient Technologies and Operations

    From fiscal 2003 to fiscal 2010, Department of Defense installation energy initiatives reduced overall energy intensity (energy use per square foot) by 11.4 percent, short of the goal of the Energy Independence and Security Act (EISA) of 2007…To continue these efforts and deploy successful initiatives across installations, the department has initiated the Installation Energy Test Bed Program, which has more than 45 demonstration projects underway and hopes to reduce demand by 50 percent in existing buildings and 70 percent in new construction…

    DoD is also exploring energy efficiency initiatives at forward operating bases. During a recent demonstration at Marine Corps Air Ground Combat Center Twenty Nine Palms in California, a company of Marines ran their equipment solely on solar and battery power for 192 hours and saved a total of eight gallons of fuel per day…As a result of the demonstrations, a group of Marines from India Company, 3rd Battalion, 5th Marines was deployed to Afghanistan in the fall of 2010 with equipment from the Experimental Forward Operating Base (ExFOB) program…Energy savings from the deployment included…

    • Two patrol bases operating entirely on renewable energy.

    • A third base reducing generator fuel use from 20 gallons a day to 2.5 gallons per day.

    • A three-week-long foot patrol that did not require a battery resupply, saving the Marines 700 pounds of weight.

    The Department of Defense is moving rapidly to examine the potential of self-contained “microgrids” that hold promise for ensuring the continuity of critical operations at domestic bases. It is estimated that DoD is reliant on civilian utility companies for 99 percent of its electricity requirements…Microgrids are self-contained islands of energy generation and management capacity that may or may not be attached to the commercial grid.

    DoD’s aggressive move toward microgrid technology is helping to spur industry growth and demonstrate technological feasibility. In part because of the numerous DoD microgrid projects underway, the U.S. microgrid market reached $4 billion in 2010…Market analysts indicate that DoD will account for almost 15 percent of the microgrid market in 2013 and that military implementation of microgrids will grow by 375 percent to $1.6 billion annually in 2020…

    Renewable Energy Generation Technology

    As the world’s largest institutional energy user and with a broad range of facilities, DoD is an important player in the development and deployment of renewable energy technologies. In fiscal 2010, the department produced or procured 9.6 percent of its electric energy consumption from renewable energy sources, just shy of the National Defense Authorization Act goal of 10 percent…

    Research: At the research level, DARPA has led a concerted effort to develop solar cells that achieve 50 percent conversion efficiency, more than twice the current rate of leading technologies. Record conversion efficiencies of greater than 40 percent have been achieved, and the public-private partnership is exploring next steps in product engineering and manufacturing…

    Deployment: As of mid-2010, the Department of Defense was operating more than 450 projects involving solar, wind, geothermal and biomass energy…The U.S. Navy accounts for 60 percent of DoD’s renewable energy projects—some 250 in total. The 14-megawatt solar array at Nellis Air Force base in Nevada is one of the largest projects in the United States, although large-scale projects in the 250 to 1,000 MW range are in development. One of the largest projects under development in the United States is a 500 MW concentrated solar power project at Fort Irwin in California. DoD renewable energy spending is projected to reach $3 billion by 2015 and $10 billion by 2030.

    Energy Storage

    Lightweight and long-lasting power is crucial for troops who need computers, radios or night-vision goggles on extended missions.

    Batteries: It is estimated that up to 20 percent34 of a soldier’s 70- to 90-pound pack consists of batteries. Army Soldiers must carry seven or more pounds of batteries for each day on mission.35 A typical infantry battalion uses $150,000 worth of batteries during a one-year deployment.36 More efficient, longer-lasting, lighter battery systems, such as the Army’s Rucksack Enhanced Portable Power System, can significantly improve mission effectiveness and mobility. Technological research into advanced battery technologies is being pursued actively by DoD and the Department of Energy, and the military is pairing rechargeable batteries with renewable energy technologies to extend soldier range and effectiveness.

    Fuel Cells: The military is also utilizing fuel cells as an additional source of portable power for troops. The benefit of fuel cell technology from a war fighting standpoint is that the cells outperform traditional batteries by up to sevenfold.37 Fuel cells are applicable to a wide range of military uses, from small amounts of power for individual soldiers to large amounts for facilities, bases and tactical vehicles. Compared with traditional generators, fuel cells are lighter, quieter, produce fewer emissions and are estimated to be 83 percent more efficient…

    In its clean energy efforts, the department is demonstrating that U.S. economic, energy and national security are inextricably linked. For DoD, today’s investments in clean energy will save lives and money for many years to come. For the nation, farsighted energy policies help reduce dependence on imported oil, create manufacturing and economic opportunities, reduce harmful pollution and make our country safer.

    With its commitment to using energy more efficiently, harnessing alternative sources of power, and developing technologies that promote a more reliable and secure electricity grid, today’s DoD is helping to point the way toward a more secure, clean and prosperous tomorrow.
