Renewable Energy: Tax Credit, Budget,
and Electricity Production Issues
High gasoline and natural gas prices have rekindled interest in the role that
renewable energy may play in producing electricity, displacing fossil fuel use, and
curbing demand for power transmission equipment. Also, worldwide emphasis on
environmental problems of air and water pollution and global climate change, the
related development of clean-energy technologies in western Europe and Japan, and
technology competitiveness may remain important influences on renewable energy
The Bush Administration’s FY2007 budget request for the Department of
Energy’s (DOE’s) Renewable Energy Program seeks $359.2 million, which is $84.0
million, or 30.5%, more than the FY2006 appropriation. In support of the President’s
proposal for an Advanced Energy Initiative (AEI), the request includes major funding
increases for solar energy (to support the Solar America initiative) and biomass (to
support the Biorefinery Initiative). The main increases are for Solar Photovoltaics
($79.5 million) and Biomass ($59.0 million). Some significant cuts were also
proposed, and the request sought to eliminate earmarks.
Appropriations actions by the House and the Senate Appropriations Committee
have approved most of the requested FY2007 funding increases for AEI and greatly
reduced earmark funding. Compared with House-passed funding, the Senate
Appropriations Committee recommendation seeks an increase of $66.1 million (5%).
Table 3 shows other differences, most notably those for Biomass & Biorefinery,
Geothermal, Hydro, and Weatherization programs.
Important regulatory issues have surfaced for wind energy. A major debate has
erupted over the safety and economic and environmental aspects of a proposal by
Cape Wind Associates to develop an offshore wind farm near Cape Cod,
Massachusetts. The parties to the debate are waiting for the results of a Department
of Interior (DOI) environmental impact statement and a Coast Guard study of
navigational safety aspects. Also, concern that large wind turbines may disrupt radar
systems led to federal actions to halt several wind farm developments, pending the
results of a study by the Department of Defense (DOD) that was due in early May
2006. In late June 2006, the Sierra Club filed suit to compel completion of the DOD
radar study. An agency of the United Kingdom has studied modifications to turbines
and radar systems that may help solve the problem.
Also, high gasoline prices have stimulated a DOE proposal for aggressive
development of cellulosic ethanol as an alternative to gasoline and corn-based
ethanol. The focus is on using biotechnology to simplify processes and reduce costs.

Renewable Energy Policy: Tax Credit, Budget,
and Regulatory Issues
Most Recent Developments
On June 29, 2006, the Senate Committee on Appropriations reported H.R. 5427,
the Energy and Water Appropriations bill for FY2007 (S.Rept. 109-274). This bill
includes funding for the Department of Energy (DOE) Renewable Energy Program,
which is conducted by the Office of Energy Efficiency and Renewable Energy
(EERE). Compared with House-passed funding, the FY2007 Senate Appropriations
Committee recommendation seeks an increase of $66.1 million (5%). Table 3 shows
other differences, most notably those for Biomass & Biorefinery, Geothermal, Hydro,
and Weatherization programs.
Compared with FY2006 funding, the Senate Committee recommends an
increase of $240.4.8 million for R&D and deployment programs. This reflects
support for the Advanced Energy Initiative, including increases for Hydrogen ($34.2
million), Biomass/Biorefineries ($59.3 million), and Solar ($65.3 million). The main
cuts include the Weatherization program (-$42.6 million), Facilities (-$20.2 million),
Industrial programs (-$9.3 million), and Program Management (-$9.9 million).
(The renewable energy provisions in the Energy Policy Act of 2005 [P.L. 109-
58, H.R. 6] and other bills of the 109th Congress are discussed in the “Renewables in
the 109th Congress” and “Legislation” sections below. A list of all renewable energy
bills introduced in the 109th Congress is provided in CRS Report RL32860, Energy
Efficiency and Renewable Energy Legislation in the 109th Congress, by Fred Sissine.)
Renewable Energy Concept
Renewable energy is derived from resources that are generally not depleted by
human use, such as the sun, wind, and water movement. These primary sources of
energy can be converted into heat, electricity, and mechanical energy in several ways.
There are some mature technologies for conversion of renewable energy such as
hydropower, biomass, and waste combustion. Other conversion technologies, such
as wind turbines and photovoltaics, are already well developed, but they have not
achieved the technological efficiency and market penetration that many expect they
will ultimately reach. Although geothermal energy is produced from geological
rather than solar sources, it is often included as a renewable energy resource (and is

treated as such in this report). Commercial nuclear power is not generally considered
to be a renewable energy resource.1
Contribution to National Energy Supply
According to the Energy Information Administration’s (EIA’s) Annual Energy
Outlook 2006, renewable energy resources (excluding wood used for home heating)
supplied about 5.7 Q (quadrillion Btu’s, or quads) of the 99.7 Q the nation used in
2004, or about 6.0% of national energy demand. More than half of renewable energy
production takes the form of electricity supply. Of this, most is provided by large
hydropower. However, from 1998 through 2001, a drought-driven decline in
hydroelectric availability led to a major drop in national renewable energy use.
Industrial use of renewables, supplied primarily by biofuels, accounts for most of the
remaining contribution.2
Some note that renewable energy, after more than 25 years of federal support,
has achieved neither a high level of market penetration nor a growing market share
among other energy sources. A 1999 review of renewable energy studies by
Resources for the Future (Renewable Energy: Winner, Loser, or Innocent Victim?)
concludes that the lower-than-projected market penetration and flat market share
were due primarily to declining fossil fuel and electricity prices during most of that
period. In contrast, however, it notes that the costs for renewable energy
technologies have declined by amounts equal to or exceeding those of earlier
projections.3 Nevertheless, the costs are still higher than those for conventional
energy.4 Even wind energy, which has a much lower cost than solar energy
technologies, owes its recent commercial success to support from the federal
renewable energy production tax credit and the renewable portfolio standard (RPS)
that many states have put in place.5
EIA’s Annual Energy Outlook 2006 projects that current policies would yield
a 1.8% average annual increase in renewable energy production to 9.0 Q through
2030, resulting in a 57% total increase. This would amount to about 6.7% of the
projected 134 Q total demand in 2030.6

Role in Long-Term Energy Supply
Our Common Future, the 1987 report of the United Nations World Commission
on Environment and Development, found that “energy efficiency can only buy time
for the world to develop ‘low-energy paths’ based on renewable sources.”7 Though
many renewable energy systems are in a relatively early stage of development, they
offer “a potentially huge primary energy source, sustainable in perpetuity and
available in various forms to every nation on Earth.” The report suggested that a
research, development, and demonstration (RD&D) program of renewable energy
projects is required to attain the level of primary energy now obtained from a mix of
fossil, nuclear, and renewable energy resources.
The Agenda 21 adopted at the 1992 United Nations Conference on Environment
and Development (UNCED, “Earth Summit”) concluded that mitigating urban air
pollution and the adverse impact of energy use on the atmosphere — such as acid
rain and climate change — requires an emphasis on “clean and renewable energy
sources.” The U.N. Division on Sustainable Development oversees implementation
of Agenda 21. The 2002 U.N. World Summit on Sustainable Development
(Johannesburg Earth Summit) adopted a Political Declaration and a Plan of
Implementation,8 which includes “Clean Energy” as one of five key policy actions.9
Subsequently, in 2003, the U.S. Department of State implemented a $42 million
Clean Energy Initiative10 and the European Union committed to a $700 million
energy partnership. Nevertheless, EIA estimates that renewable energy’s share of
global energy consumption through 2030 will remain limited to less than 9% for the
next two to three decades.11
The oil embargo of 1973 sparked a quadrupling of energy prices, major
economic shock, and the establishment of a comprehensive federal energy program
to help with the nation’s immediate and long-term energy needs. During the 1970s,
the federal renewable energy program grew rapidly to include basic and applied R&D
and federal participation with the private sector in demonstration projects,
commercialization, and information dissemination. In addition, the federal
government instituted market incentives, such as business and residential tax credits,
and created a utility market for nonutility-produced electric power through the Public
Utility Regulatory Policies Act (P.L. 95-617).

11 EIA, International Energy Outlook 2006, Table A8 (World Consumption of
Hydroelectricty and Other Renewable Energy, 1990-2030) and Table A1(World Energy
Consumption, 1990-2030), at [].

The subsequent failure of the oil cartel and the return of low oil and gas prices
in the early 1980s slowed the federal program. Despite Congress’s consistent support
for a broader, more aggressive renewable energy program than any Administration,
federal spending for these programs fell steadily through 1990. Until 1994, Congress
led policy development and funding through legislative initiatives and close reviews
of annual budget submissions. FY1995 marked a noteworthy shift, with the 103rd
Congress for the first time approving less funding than the Administration had
requested. The 104th Congress approved 23% less than the Clinton Administration
request for FY1996 and 8% less for FY1997. However, funding turned upward again
during the 105th and 106th Congresses, and stayed relatively flat through the 107th and

108th Congresses and the first session of the 109th Congress.12

From FY1978 through FY2005, the DOE spent about $13.4 billion (in 2005
constant dollars) for renewable energy R&D. Renewable energy R&D funding grew
from less than $1 million per year in the early 1970s to more than $1.4 billion in
FY1979 and FY1980, then declined steadily to $148 million in FY1990. By
FY2005, it reached $380 million in 2005 constant dollars.
This spending history can be viewed within the context of DOE spending for the
three major energy supply R&D programs: nuclear, fossil, and energy efficiency
R&D. From FY1948 through FY1977 (in 2005 constant dollars), the federal
government spent about $42.6 billion for nuclear (fission and fusion) energy R&D
and about $14.1 billion for fossil energy R&D. From FY1978 through FY2005, the
federal government spent $33.9 billion for nuclear (fission and fusion), $21.1 billion
for fossil, $13.4 billion for renewables, and $12.4 billion for energy efficiency. Thus,
total energy R&D spending from FY1948 to FY2005, in 2005 constant dollars,
reached $140.0 billion, including $76.5 billion, or 55%, for nuclear; $35.2 billion, or
25%, for fossil; $13.4 billion, or 10%, for renewables; and $12.4 billion, or 9%, for
energy efficiency.
In FY2006, as part of a restructuring of the appropriations committees, Congress
merged appropriations accounts for the DOE Energy Efficiency Program, which
previously had been under the Department of Interior and Related Agencies
Appropriations Bill, with the appropriations accounts for the DOE Renewable Energy
Program under the Energy and Water Development Appropriations Bill. As a result,
appropriations for some subprograms of the Renewable Energy Program, such as
Hydrogen and Program Management, are commingled with those for the Energy
Efficiency Program and are no longer reported separately. In place of the former
totals for the Renewable Energy Program, this report now shows a subtotal of
appropriations for all of the renewable energy technology subprograms, namely
Biomass and Biorefinery, Solar, Wind, Geothermal, and Small Hydro subprograms
(see Table 3). The total for these subprograms was $242.5 million for FY2005 and
$236.2 million for FY2006.

12 A detailed description of DOE programs appears in DOE’s FY2007 Congressional Budget
Request, DOE/ME-0053, v. 3, February 2006, at [
Content/V olumes/vol_3_ES.pdf].

Tax Credits. The Energy Tax Act of 1978 (P.L. 95-618) created residential
solar credits and residential and business credits for wind energy installations; it13
expired on December 31, 1985. However, business investment credits were
extended repeatedly through the 1980s for solar, geothermal, and ocean thermal
energy technologies. Section 1916 of the Energy Policy Act of 1992 (P.L. 102-486)
extended the 10% business tax credits for solar and geothermal equipment14
indefinitely. Also, Section 1914 created a “production” tax credit (PTC) of 1.5
cents/kwh (adjusted annually for inflation) for electricity produced by wind and15
closed-loop biomass. P.L. 106-170 expanded this credit to include poultry waste.
The JOBS Act (P.L. 108-357) expanded the PTC (adding solar, geothermal, and
open-loop biomass, landfill gas, trash combustion, and certain small hydro) and
extended it through the end of 2005. In August 2005, the Energy Policy Act of 2005
(EPACT, P.L. 109-58) made the PTC retroactively effective to the beginning of 2005
and extended it through the end of 2007. In addition, P.L. 96-223 created an income
tax credit for alcohol fuels; section 9003(a)(3) of P.L. 105-178 extended the 40-60
cents/gallon credit through December 31, 2007. Further, the Energy Tax Act created
a 4.0 cents/gallon federal excise tax exemption for gasohol (gasoline blended with
alcohol). The JOBS Act (P.L. 108-357) reformed this subsidy, converting the
exemption to an equivalent tax credit, which now stands at 5.1 cents/gallon for a 10%
ethanol blend.
Public Utility Regulatory Policies Act. The Public Utilities Regulatory
Policies Act (PURPA, P.L. 95-617) required electric utilities to purchase power
produced by qualified renewable power facilities. Under PURPA, the Federal Energy
Regulatory Commission (FERC) established rules requiring that electric utilities
purchase power from wind farms and other small power producers at an “avoided
cost” price based on energy and capacity costs that the utility would otherwise incur
by generating the power itself or purchasing it elsewhere. However, Section 1253
of P.L. 109-58 terminated the mandatory purchase and sale requirements for a new
renewable power facility, provided that FERC finds that the new facility has access
to wholesale power markets and transmission services.
State and Local Government Roles. State and local governments have
played a key role in renewable energy development. For example, in the early 1980s,
a generous state investment tax credit for wind energy in California combined with
PURPA and the federal tax credit to stimulate industry development of the first wind
farms. California and New York have invested some state funds in renewable energy
R&D. Recently, Texas and about 20 other states have used a regulatory tool, the
renewable energy portfolio standard (RPS), to encourage renewable energy. Also,
in 2001, the city of San Francisco enacted a $100 million revenue bond (Proposition

of Honolulu approved a $7.85 million solar and energy efficiency bond.16
Renewables in the 109th Congress
Action in the Second Session
DOE Budget, FY2007. On February 6, 2006, President Bush issued the
Administration’s budget request for FY2007. The DOE request seeks $359.2 million
for renewables, which is $84.0 million, or 30.5%, more than the FY2006
appropriations (excluding inflation). The Administration’s request includes funding
for an Advanced Energy Initiative (AEI) as part of its American Competitiveness
Initiative (ACI), which includes accelerated funding for the Solar America and
Biorefinery initiatives under DOE’s Renewable Energy Program. For more budget
details, see “DOE Budget, FY2007” and Table 3.17
The House Appropriations Committee report (H.Rept. 109-474) includes several
policy directives to the Office of Energy Efficiency and Renewable Energy (EERE).
First, it says (pp. 72-73) that EERE could have avoided employee layoffs at the
National Renewable Energy Laboratory (NREL) through better management of
uncosted balances, and directs EERE to report by January 31, 2007, on steps taken
to identify prior year balances and account for all out-year commitments. Second,
the report directs (p. 73) EERE to report by January 31, 2007, on the progress of
implementing the Inspector General’s recommendations (IG audit report DOE/IG-
0689) to improve the management of cooperative agreements. Further, the report
directs (pp. 74-75) EERE to fully fund a biomass R&D grant to Natureworks LLC,
strengthen recruiting from Historically Black Colleges and Universities, and to
prepare a report on solar water heaters by January 31, 2007, that covers potential
energy savings, market impediments, and deployment strategy. Also, one DOE-wide
directive that would directly affect EERE involves funding for the Asia Pacific
Partnership (APP), which would support clean, energy-efficient technologies. The
report directs (pp. 67-68) DOE to submit a reprogramming request if it intends to
support APP with FY2006 funds and to submit a detailed budget justification (which
would be considered by the conference committee) if it proposes to use FY2007
The Senate Appropriations Committee report (S.Rept. 109-274) on Energy and
Water Development Appropriations for FY2007 includes several policy directives
to EERE for the Renewable Energy Program. First, it recommends (p. 116) that
DOE complete unfinished awards for biorefineries before funding new ones. It urges

that DOE focus on cellulosic ethanol to reduce oil imports, and directs DOE to
recommend ways to implement the cellulosic biomass production incentive in
EPACT (P.L. 109-58, §942). Second, the Committee joins with the House in
requiring (p. 117) a report on solar water heaters. Third, it urges (p. 117) DOE to
focus on non-silicon materials and directs DOE to prepare a report by March 31,
2007, on short- and long-term silicon market conditions and the potential impact on
the photovoltaic market. Fourth, it recommends (p. 117) a $9 million increase to
support deployment of a solar-hydrogen pilot plant that would fulfill certain sections
of EPACT. Fifth, the Committee directs (p. 117) that funding for a 1 MW solar
thermal facility can only be used for deployment in New Mexico. Sixth, it requests
(pp. 117-118) that EERE and the Office of Electricity (OE) provide a report by
March 2007 that identifies the most promising locations for wind resources and the
best opportunities for integrating these potential power generation facilities into the
electric grid. Seventh, it encourages (p. 118) DOE to form an interagency group to
promote renewable energy use in all aspects of federal agency operations, especially
those on federal lands. In particular, this group should address the issue of wind
energy project delays due to Department of Defense concerns about radar
interference. Eighth, it recommends (p. 118) that $2.4 million be provided as a
competitive award for development of a 2 MW permanent magnet motor wind
turbine, which has the potential to eliminate the need for gearboxes. Ninth, it directs
(p. 118) that funding for Hydropower include a study of advanced techniques for
ocean energy, including an assessment of locations for demonstration plants, with a
report by May 1, 2007. Tenth, it directs (pp. 118-119) DOE to study possible
impacts of plug-in hybrids on electricity supply and distribution networks, including
urban areas, and to study environmental aspects of fuel-switching. Eleventh, it
directs (p. 119) DOE to provide a strategy to accelerate the development of zero
energy buildings by five to seven years.
U.S. Department of Agriculture (USDA) and Other Appropriations
Action, FY2007. At least three other appropriations bills include some funding for
renewable energy programs. These actions are summarized in Table 1, below, and
program descriptions follow. First, the Farm Security Act of 2002 (§9006) created
the USDA Renewable Energy Program to provide grants and loans to agriculture
producers and rural small businesses for renewable energy systems and energy
efficiency improvements. Second, under the Department of State, the Clean Energy
program was created to support the use of renewable energy and energy efficiency
to reduce greenhouse gas emissions in developing countries. In addition, the Clean
Energy Technology Exports Initiative (CETEI) was created by language in the
conference report on the FY2004 Energy and Water Development Appropriations
bill.18 Further, in January 2006, the Bush Administration announced that it would
seek $50 million in FY2007 for the Asia Pacific Partnership on Clean Development

18 The conference report (H.R. 5427, H.Rept. 108-357, p. 142) created an interagency group
led by DOE, which was directed to provide a report to Congress by January 15, 2004, on the
status of the implementation of the CETEI strategic plan and specific actions that each of
the participating agencies had taken in FY2003 and planned to take in FY2004 to engage
non-governmental, private sector, and other international partners. In addition, the conferees
directed DOE to make $400,000 available to establish an interagency CETEI center in the
Office of International Energy Market Development.

and Climate. Third, the Defense Appropriations Bill would fund a wind turbine
demonstration project at a military base.

Offshore Wind Farms and the Cape Wind Issue. Major commercial
wind farm developments in the United States and some European nations have
expanded from land-based operations to offshore coastal areas. Offshore wind farms
have grown rapidly in Europe, especially in the coastal areas of Germany, the United
Kingdom, and Ireland. In the United States, proposals have been made primarily for
offshore areas near Texas and the mid-Atlantic and northeast states.
A major issue erupted over the Cape Wind Associates proposal for a $1 billion
offshore development that would install 450 megawatts (millions of watts) of wind
turbine capacity in federal waters, the Horseshoe Shoal area, near Cape Cod in
Massachusetts.19 Cape Wind made the initial project application to the U.S. Army
Corps of Engineers in November 2001. The development would include 130 wind
turbines, each rated at 3.6 megawatts, reaching 420 feet high (with the hub 260 feet
above the surface of the water), and spread over a 24 square-mile area about six miles
offshore.20 The Corps of Engineers prepared a draft environmental impact statement21
that was released in November 2004. In August 2005, the Energy Policy Act

[] .

(EPACT, §388) shifted regulatory responsibility to the Minerals Management Service
at the Department of Interior.22
Cape Wind Associates and other proponents say the project is a safe, clean way
to develop renewable energy and create jobs. Cape Wind lists supporters that include
local towns and citizen groups, renewable energy groups, labor organizations
(including the Seafarers International Union), academic and scientific leaders, and
college organizations. Other proponents include national environmental groups, such
as the Natural Resources Defense Council (NRDC)23 and the Union of Concerned
Scientists.24 In regard to energy development, they claim that the project would
reduce air pollutants and greenhouse gases that would otherwise be generated by
conventional power plants. Regarding jobs, they contend that dozens of construction
jobs will be created for an 18-month period, with spin-off benefits to local
businesses, and that afterwards, year-round jobs will be created to monitor, operate,
and maintain the wind farm. In regard to the environment, they claim that from the
shore, there will be only a minimal impact on the viewshed. Regarding the tourism
industry, they argue that new opportunities will be created for up-close, “majestic
views” of the wind towers, which will only be possible from tour boats. Further, they
argue that charter fishing boats, sailboat tours, and scenic cruises may include the
wind farm as part of the Cape Cod experience.25
Opponents of the Cape Wind project have collaborated to create the Alliance to
Protect Nantucket Sound, which includes several local towns, business and tourism
organizations, commercial fishing groups, recreational fishing and boating groups,
and boating safety and navigation organizations.26 The opponents say that the
proposed development poses dangers to the area’s ecosystem, maritime navigation,
and the Cape Cod tourism-based economy. Regarding the viewshed, the Alliance

22 EPACT transferred federal regulatory authority over the project to the U.S. Department
of Interior’s Minerals Management Services (MMS). MMS already had jurisdiction for oil
and gas development in the offshore region of the Outer Continental Shelf, and EPACT
expanded this authority to include renewable energy development, covering wind and wave
energy; see [].
23 In a press release, NRDC stated qualified support for the project: “... it is crucial for us
to set the bar [for environmental standards] in the right place. The air quality, public health,

notes that many land-based landmarks smaller than the wind turbines — including
a light house, radio antenna, and water towers — are easily seen from the project site.
In regard to birds, it stresses that the area is one of the most important migratory
staging areas on the East Coast, providing habitat for some endangered species.
Regarding fishing, it says that it is one of the richest fishing grounds on the East
Coast, many local fishermen make 60% of their income on Horseshoe Shoal, and no
fishing or boating group supports the project. The Alliance cites a study that found
tourist-related spending would be cut by nearly $200 million per year. Also, the
group reports that commercial ferry lines see serious navigation hazards, local airport
commissions see safety concerns, and the wind turbines may interfere with radar
Under its new authority,28 MMS became the lead federal agency regulating the
development of the proposed Cape Wind project.29 As directed by EPACT (§388),
MMS is preparing an environmental impact statement (EIS).30 As part of the EIS
activity, MMS is considering potential alternatives to the Cape Wind proposal, such
as modifying the size of the development, phasing it, reconfiguring it, and relocating
it to alternative sites.31
Section 414 of the Coast Guard and Maritime Transportation Act of 2006 (P.L.
109-241, H.R. 889) directs the Commandant of the Coast Guard to “specify the
reasonable terms and conditions the Commandant determines to be necessary to
provide for navigational safety” for the proposed Cape Wind energy facility in
Nantucket Sound.32 Further, it directs MMS to incorporate these terms and
conditions into any lease, easement, or right-of-way for the facility.33

28 Prior to EPACT, the U.S. Army Corps of Engineers had authority over th Cape Wind lease
proposal, and the Corps had completed more than four years of reviews on the proposals,
which will be considered by MMS.

Wind Disruption of Radar Issue. There is a concern that tall wind turbines
may create false signals that would be picked up by military and civilian radar.34
Section 358 of the Defense Authorization Act for FY2006 (P.L. 109-163, H.R. 1815)
requires the Department of Defense (DOD) to submit a report to Congress on
... the effects of windmill farms on military readiness, including an assessment
of the effects on the operations of military radar installations ... and of
technologies that could mitigate any adverse effects on military operations35
The law was enacted on January 6, 2006, and Section 358 specifies that the
report is due 120 days after enactment, which would have occurred in early May

2006. As of the date of this CRS report, the DOD report had not been issued.36

On March 21, 2006, the DOD and the Department of Homeland Security (DHS)
issued an Interim Policy on Proposed Windmill Farm Locations, which states that
[t]he DOD/DHS Long Range Radar Joint Program Office Interim Policy is to
contest any establishment of windmill farms within radar line of site of the
National Air Defense and Homeland Security Radars. This is to remain in effect37
until the completion of the study and publishing of the Congressional Report.
The American Wind Energy Association (AWEA) contends that many wind
farm projects have received a Notice of Presumed Hazard from the Federal Aviation
Administration (FAA) and have halted development. This, it says, includes projects38
in Wisconsin, Illinois, North Dakota, South Dakota, and Minnesota. Defense and
FAA officials say the “proposed hazard” letters do not prohibit wind farms, they just39
delay them until any risks to military operations can be assessed and resolved.
However, the wind industry is anxious about any delay in construction because the

renewable energy production tax credit is set to expire at the end of 2007.40 On June
2, six Senators from Illinois, Wisconsin, and North Dakota sent letters of concern to
DOD about the interim policy of halting wind farms classified as within “radar line
of sight” while the study is being completed.41 On June 28, the Sierra Club filed suit
against DOD for delaying the study of wind farm impact on radar mandated by the
Defense Authorization Act.42
The British Department of Trade and Industry (DTI) has supported studies of
the radar problem for wind farms in the United Kingdom. A 2003 DTI study found
that there is a potential for wind turbines to significantly affect the performance of
air traffic control radar. The two general categories of effects are reports of false
targets (aircraft) to the radar operator and a reduction in the likelihood of detecting
aircraft. This study recommended that the problem could be addressed by modifying
the design and installation of both the turbines and the radar systems.43 A 2005 DTI
study modeled the use of radar absorbent materials (RAM) in wind turbine blades.44
It found that RAM materials can be developed with minimal structural impact,45 and
recommended that a turbine outfitted with such materials be field-tested. Also, DTI
formed a partnership with the British Wind Energy Association (BWEA) to fund
research on an advanced digital tracker to mitigate the radar problem. Both the
Ministry of Defence and the National Air Traffic Services began planning flight trials
in late 2005.46 In 2006, the two agencies decided to conduct tests with Royal Air
Force (RAF) aircraft in a location in Wales near four working wind farms.47

Energy Policy Act of 2005 (EPACT, H.R. 6, P.L. 109-58)
Renewable Energy Portfolio Standard (RPS). For retail electricity
suppliers, an RPS sets a minimum requirement (often a percentage) for electricity
production from renewable energy resources or for the purchase of tradable credits
that represent an equivalent amount of production. A growing number of states have
enacted an RPS, currently including 19 states and the District of Columbia.48
The Senate Committee on Energy and Natural Resources held a hearing on RPS
on March 8, 2005. Regional differences in the availability of renewable resources,
particularly resource availability in the southeastern United States, was a key issue
of the discussion. In the markup of a committee print (to be incorporated into H.R.
6) by the House Committee on Energy and Commerce, an amendment to add an RPS
(1% in 2008, increasing by 1% annually through 2027) was rejected (17-30).
Proponents noted a growing number of states with an RPS and that EIA reports show49
an RPS could reduce electricity bills. Opponents raised concerns about the
exclusion of existing hydropower facilities and resource limits for the southeastern
United States.
There was no RPS provision in the House version of H.R. 6. The Senate
version had a 10% RPS provision. During the conference, there was an idea put out
to compromise by including nuclear and hydropower facilities. Nevertheless, RPS
was dropped in conference.50
Renewable Energy Production Tax Credit (PTC). The House version
of H.R. 6 had no PTC extension, the Senate version had a three-year extension, and
the enacted law (§1301) extends the PTC for two years, through the end of calendar51
year 2007. For claims against 2005 taxes, the credit is valued at about 1.9 cents per
kilowatt-hour (kwh) for electricity produced by facilities that use wind, closed-loop
biomass, poultry waste, geothermal energy, or solar energy. Also, half credit (valued
at about 0.9 cents/kwh in 2005) is available for electricity produced by facilities that
use open-loop biomass, incremental hydropower, municipal solid waste (landfill gas),
or small irrigation water flows.

Energy, at []. Search by “incentive type,” then “portfolio

Renewable Energy Production Incentive (REPI). Parallel to the PTC,
there is a renewable energy production “incentive” (REPI) for state and local
governments and nonprofit electrical cooperatives. This 1.5 cent/kwh incentive was
created by the Energy Policy Act of 1992 (P.L. 102-486) §1212 and is funded by
appropriations to DOE. Eligible facilities currently include solar, wind, biomass
(except municipal solid waste), and geothermal energy (except certain types of dry
steam geothermal energy). The Energy Policy Act of 2005 (§202) expands REPI to
include ocean and wave energy and extends the authorization through FY2016.
Renewable Fuel Standard (RFS). P.L. 109-58 (H.R. 6, §1501) defines
“renewable fuel” to include ethanol, biodiesel, and natural gas produced from
landfills, sewage treatment plants, and certain other sources. Ethanol is the
renewable motor fuel produced in greatest quantity. In 2004, about 3.9 billion
gallons of ethanol were blended with gasoline.52 In 2005, about 75 million gallons
of biodiesel were used. In the House version of H.R. 6, the RFS provision called for
renewable fuels (primarily ethanol) production to reach 3.1 billion gallons a year in
2005, and then increase stepwise to 5.0 billion gallons a year by 2012. In the Senate
version of H.R. 6, the RFS called for 4.0 billion gallons in 2006, rising to 8.0 billion
gallons in 2012. The enacted version (§1501) set a standard starting at 4.0 billion
gallons in 2006 and rising to 7.5 billion gallons by 2012. Further, an increased
incentive would encourage the use of cellulosic and waste-derived ethanol to help
fulfill the RFS target.53 The previous incentive was created by crediting 1.0 gallon
of cellulosic or waste-derived ethanol as equivalent to 1.5 gallons of renewable fuel.
Under EPACT, it becomes equivalent to 2.5 gallons of renewable fuel.
Renewable Hydrogen. P.L. 109-58 (H.R. 6, §933) would create a program
to produce hydrogen from a variety of sources, including renewable energy and
renewable fuels, as part of a broader effort to develop hydrogen fuels, vehicles, and
infrastructure. The provision includes a focus on distributed energy that uses
renewable sources. Another section (§812) also calls for use of renewable hydrogen
as part of a hydrogen fueling and infrastructure demonstration program.
Renewables Tax Revenue Effect. Table 2 shows the estimated 11-year
revenue effect of renewable energy tax provisions in the House version of H.R. 6
(H.R. 1541), the Senate version of H.R. 6, and the enacted law.

Renewable Energy Production
Electricity Production from Renewables
The Public Utility Regulatory Policies Act (PURPA) was a key to the growth55
of electric power production from renewable energy facilities. After 1994, state

54 Additional bills with renewable energy provisions are identified in CRS Report RL32860,
Energy Efficiency and Renewable Energy Legislation in the 109th Congress, by Fred Sissine.
55 PURPA required electric utilities to interconnect with renewable energy power facilities
and to pay a price (avoided cost) that was determined by each state.

actions to restructure56 the electric utility industry dampened PURPA’s effect.57 At
the same time, however, the renewable energy production tax credit (PTC) grew in
importance as a major incentive, helping to spur the development of independent
wind energy power producers.58 In the 109th Congress, P.L. 109-58 (§1253) includes
a conditional repeal of the mandatory renewables purchase requirement in Section

210 of PURPA.59

Renewables Under Electric Industry Restructuring. To encourage a
continued role for renewable energy under restructuring, some states and utilities
have enacted measures such as a renewable energy portfolio standard (RPS), public
benefits fund (PBF), and/or “green” pricing and marketing of renewable power. The
above section on “Renewable Portfolio Standard” summarizes the RPS action in H.R.
6, including a Senate proposal that was rejected in conference committee. Since the
enactment of P.L. 109-58, several bills with an RPS provision have been introduced,
including H.R. 4384 (§205), H.R. 5331 (§504), H.R. 5642 (§4), S. 2435 (§6b), S.

2571 (§504), and S. 2747 (§301).

Green Power. The term “green power” generally refers to electricity supplied
in whole or in part from renewable energy sources. Green power marketing (retail
or wholesale) is underway in California, Illinois, Massachusetts, New Jersey, New
York, Pennsylvania, and Texas. Green pricing is an optional utility service that
allows electricity customers who are willing to pay a premium for the environmental
benefits of renewable energy to purchase green power instead of conventional power.

56 For a discussion of broader electricity restructuring issues, see CRS Report RL32728,
Electric Utility Regulatory Reform: Issues for the 109th Congress, by Amy Abel.
57 Electricity restructuring aimed to create competition in electricity markets, primarily by
deregulating electricity generation and opening access to utility transmission lines (retail
wheeling) for all electricity producers.
58 Further, near the turn of the century, states began to establish a renewable energy portfolio
standard (RPS) that required retail electricity suppliers to produce a fixed minimum amount
of electricity from renewables. The RPS, working together with the PTC, has also become
a significant incentive for renewable energy power production.
59 The conditions are that the cogeneration or small power production facility has
nondiscriminatory access to — A(i) independently administered, auction-based day ahead
and real time wholesale markets for the sale of electric energy; and (ii) wholesale markets
for long-term sales of capacity and electric energy; or (B)(i) transmission and
interconnection services that are provided by a Commission-approved regional transmission
entity and administered pursuant to an open access transmission tariff that affords
nondiscriminatory treatment to all customers; and (ii) competitive wholesale markets that
provide a meaningful opportunity to sell capacity, including long-term and short-term sales,
and electric energy, including long-term, short-term and real-time sales, to buyers other than
the utility to which the qualifying facility is interconnected. In determining whether a
meaningful opportunity to sell exists, the Commission shall consider, among other factors,
evidence of transactions within the relevant market; or (C) wholesale markets for the sale
of capacity and electric energy that are, at a minimum, of comparable competitive quality
as markets described in subparagraphs (A) and (B).

Utility green pricing programs are available to more than one-third of the nation’s
Distributed Energy. Distributed energy involves the use of small, modular
electricity generators sited close to the customer load that can enable utilities to defer
or eliminate costly investments in transmission and distribution system upgrades, and
provide customers with quality, reliable energy supplies that may have less
environmental impact than traditional fossil fuel generators. Technologies for
distributed electricity generation use wind, solar, bioenergy, fuel cells, gas
microturbines, hydrogen, combined heat and power, and hybrid power systems. A
DOE study, Structural Vulnerability of the North American Power Grid, suggests
that adding more distributed power generation could help reduce grid vulnerability.61
Another DOE study, Homeland Security: Safeguarding America’s Future with
Energy Efficiency and Renewable Energy Technologies,62 provides a broad look at63
the potential to address vulnerabilities.
Net Metering. Net metering allows customers with generating facilities to
“turn their electric meters backwards” when feeding power into the grid; they receive
retail prices for the excess electricity they generate. This encourages customer
investment in distributed generation, which includes renewable energy equipment.
About 40 states have some form of net metering in place. P.L. 109-58 (§1251)
provides for net metering.
Natural Gas and Renewables
In January 2005, the Senate Energy and Natural Resources Committee held a
natural gas conference. Some participants described the potential for renewable
energy to augment gas supplies, reduce gas demand, and thereby help reduce natural
gas prices.64 Some of these statements referred to a 2005 DOE study entitled Easing
the Natural Gas Crisis: Reducing Natural Gas Prices through Increased Deployment
of Renewable Energy and Energy Efficiency.65
Biomass-Generated Synthetic Natural Gas (Syngas). Continuing high
natural gas prices have created interest in using renewables to dampen natural gas
demand. Renewable energy (mainly biomass) can be used to produce methane (the

main component of natural gas), which could possibly substitute directly for natural
gas. DOE projects that by 2020, biomass and energy crops could produce 15% of
natural gas needs. A 2005 Harvard University study, The National Gasification
Strategy,66 cites a Princeton University study, A Cost-Benefit Assessment of Biomass
Gasification Power Generation in the Pulp and Paper Industry,67 that says that
biomass-generated “black liquor” and wood waste could produce enough syngas to
support 25 billion watts (gigawatts) of natural gas-fired power plant capacity by


Substituting Electricity from Renewables for Gas-Fired Generation.
Also, a variety of renewables can generate electricity that indirectly displaces natural
gas use for power generation. For many utilities, the peak demand (often supported
with natural gas peak-load plants) occurs during hot summer afternoons. In many
regions, solar and wind energy reach high levels during summer peak periods. The
American Wind Energy Association (AWEA) says that at the end of 2005, wind
farms were saving more than 0.5 billion cubic feet (Bcf) of natural gas per day.

Transportation Fuels Produced from Renewables
Corn Ethanol. In the United States, ethanol is produced mainly from corn70
and is most frequently used as a 10% blend with gasoline. Historically, high cost has
been a key barrier to commercial use, which has been addressed mainly by a 51-cent71
per gallon tax credit for fuel use. Due primarily to the use of fertilizer, which has
natural gas as a key ingredient, there has been a debate over the net energy benefit of
using corn ethanol. The perception that ethanol use has significantly lower emissions
of some air pollutants than gasoline helps maintain support for its incentives.72

Efficient Economy’s report Impacts of Energy Efficiency and Renewable Energy on Natural
Gas Markets, available at [].
70 In other countries, such as Brazil, ethanol is often made from cane sugar.
71 David Morris of the Institute for Local Self-Reliance says that, with recent high gasoline
prices, ethanol is now price competitive. However, given the uncertainty about the stability
of high prices, he proposes “that half the current 51 cent per gallon incentive be converted
into an indexed incentive.” See his article, The New Ethanol Future Demands a New Public
Policy, June 21, 2006, at [].
72 For more information about ethanol developments and issues, see CRS Report RL33564,
Alternative Fuels and Advanced Technology Vehicles: Issues in Congress, and CRS Report

However, compared with gasoline, ethanol can have higher emissions of volatile
organic compounds (VOCs) per mile traveled.73 Assuming that the net energy
benefit of ethanol is clearly positive, then its carbon dioxide emissions are
significantly lower than those for gasoline.74
National ethanol production was estimated at 4.0 billion gallons in 2005.75 Due
to ethanol’s lower heat content,76 this is equivalent to about 2.7 billion gallons of
gasoline that year, or about 170,000 barrels of oil per day. In comparison, in 2005,
U.S. transportation oil use averaged 13.82 million barrels per day (mb/d) and total
U.S. oil use averaged 20.7 mb/d.77 Thus, in 2005, ethanol production accounted for
about 1.2% of transportation fuel use and about 0.8% of total oil use.
EPACT (P.L. 109-58, §1501) established a renewable fuel standard that sets a
target to increase renewable fuel production to 7.5 billion gallons per year by 2012.
This target is expected to be met primarily with ethanol, and it would be equivalent
to about 330,000 barrels of oil per day (b/d). Further, EIA estimates ethanol
production may reach 700,000 b/d by 2030.78 This would be equivalent to about
470,000 b/d of oil use. In comparison, EIA estimates that total U.S. oil use will reach
about 25 mb/d.79 Using these estimates suggests that ethanol would displace about

1.9% of total oil use in 2030.

Cellulosic Ethanol. Corn and other starches and sugars are only a small
fraction of biomass that can be used to make ethanol. Advanced bioethanol
technology could allow fuel ethanol to be made from cellulosic (plant fiber) biomass,

such as agricultural and forestry wastes, industrial waste, municipal solid waste
(organic material), trees, and grasses.80 Cellulosic ethanol can be made through
gassification, thermochemical, and microbial processes. In the microbial process,
cellulosic ethanol is made by breaking apart the cellulose (fiber) in plant cell walls
into component sugar molecules, which microbes then convert to ethanol.81
In particular, ethanol can be produced from dedicated fuel crops, such as fast-
growing trees and switchgrass. The latter is a native grass that grows well on
cropland and marginal lands, needing little water and no fertilizer. Because fertilizer
is not needed, the net energy production is much higher than that for corn ethanol.
Due to its capacity for production on marginal lands, the potential growing area for
switchgrass is much larger than that for corn. A provision in the Farm Security Act
of 2002 (P.L. 107-171) encourages use of the Conservation Reserve Program lands
for development of such biomass resources.82
Although cellulosic feedstocks may be cheaper and more plentiful than corn,
they require more extensive processing that makes the conversion to ethanol more
costly. Both DOE and USDA are conducting research to improve this technology
and reduce costs. In particular, DOE is studying the use of enzymes and heat as
catalysts to reduce the cost of the conversion process. Both the United States and
Canada have pilot facilities for producing cellulosic ethanol, and Canada has the only
commercial-scale plant in operation.83
The Administration’s Biorefinery Initiative, part of its Advanced Energy
Initiative (AEI), aims to increase funding for cellulosic ethanol development with the
goal of accelerating its commercial use.84 In response to the AEI, DOE set a goal of
using biofuels to displace 30% of national transportation fuel use (at the 2004 level)
by 2030. In July 2006, DOE announced a partnership between EERE and the Office
of Science to pursue use of biotechnology to produce cellulosic ethanol. A report on

the research strategy of the partnership says that the United States could produce up
to 60 billion gallons of biofuels per year, which would be equivalent to about 2.6
million barrels of oil per day.85 The research plan is focused on achieving
breakthroughs in biotechnology to increase the quantity of biomass (e.g., corn plant
waste and switchgrass) per acre and breeding the plants to have less lignin and more
cellulose. The plan also aims to achieve biorefinery breakthroughs that would reduce
the number of steps in the conversion process and shift the process focus from
chemical steps to biological steps in order to reduce waste byproducts and cut costs.86
Biodiesel. Biodiesel has been produced and used in stationary applications
(heat and power generation) for nearly a century, but its use as a transportation fuel
is recent.87 DOE notes that this alternative to petroleum-based diesel fuel is a
domestically produced, renewable fuel that can be manufactured from vegetable oils,
animal fats, or recycled restaurant greases.88 Further, DOE says biodiesel is safe and
biodegradable and reduces air pollutants such as particulates, carbon monoxide,
hydrocarbons, and air toxics; but it also notes that biodiesel tends to increase89
emissions of nitrous oxides. Blends of 20% biodiesel (B20) with 80% petroleum
diesel can generally be used in unmodified diesel engines. Biodiesel can also be used
in its pure form (B100), but it may require certain engine modifications to avoid
maintenance and performance problems and may not be suitable for wintertime use.90
Other challenges include resource availability and the establishment of a retail
distribution network.91

85 DOE, Factsheet on a Scientific Roadmap for Cellulosic Ethanol, p. 1. Assuming that the
60 billion gallons per year is provided by ethanol, that would be equal to 3.9 million barrels
per day of ethanol. Using the fact that ethanol has about 67% of the heat content of gasoline
by volume yields an estimate of 2.6 million barrels of oil per day. See

Biodiesel appears to have a net energy production much higher than that for
corn ethanol and slightly higher than that for petroleum diesel.92 U.S. biodiesel
production has increased from less than 1 million gallons in 1999 to an estimated 75
million gallons in 2005.93 The latter figure is equivalent to about 5,000 barrels of oil
per day and is less than 1% of total diesel fuel use for transportation.94 EIA projects
that biodiesel production could reach the equivalent of 20,000 barrels of oil per day
by 2030.95
The American Jobs Creation Act of 2004 (P.L. 108-357, §301) created an excise
tax credit for biodiesel fuel blending. The credit is set at $1.00 per gallon of
biodiesel used.96 Because the credit is fixed on a volume (per gallon) basis, a 20%
biodiesel blend (B20) would be eligible for a 20 cent per gallon credit, and a 100%
biodiesel fuel (B100) would be eligible for a $1.00 per gallon credit.97 EPACT
(§1344) extended this credit through the end of 2008. Further, EPACT (§1501)
created a renewable fuel standard (RFS),98 which allows for biodiesel production to
contribute to achievement of the standard.99
Climate Change and Renewables
Because in most cases renewable energy appears to release less carbon dioxide100
(CO2) than fossil fuels, renewables are seen as a key long-term resource that could

95 EIA, Annual Energy Outlook 2006, p. 52. This is the estimate for the reference case.
96 The $1.00 per gallon credit is for biodiesel derived from first-use oils, such as soybean oil.
For biodiesel obtained from second-use oils, such as recycled cooking oil, the credit is set
at half that value.
97 Thus, the maximum credit for biodiesel derived from second-use oils is 50 cents per
gallon for B100.
98 However, the share of RFS allocated to biodiesel and other details are to be determined
through a rulemaking by the Environmental Protection Agency due August 8, 2006.
Meanwhile, EPA has posted the default rule at [
renewablefuels/420f05057.htm] .
99 EPACT has other provisions supporting biodiesel, including an authorization for an
engine-testing program (§757), a 10-cent per gallon tax credit for small agri-biodiesel
producers (§1345), and a requirement that DOE prepare a report on the future potential for
biodiesel fuel (§1823).
100 Because renewable energy is often developed for energy security, air pollution reduction,

substitute for fossil energy sources used to produce vehicle fuels and electricity. The
percentage of renewable energy substitution depends on technology cost, market
penetration, and the use of energy efficiency measures to control energy prices and
demand. DOE’s November 2005 report U.S. Climate Change Technology Programs
— Technology Options for the Near and Long Term compiles information from
multiple federal agencies on more than 80 technologies.101 For these end-use and
supply technologies, the report describes President Bush’s initiatives and R&D goals
for advancing technology development, but it does not estimate emissions saving
potentials, as some previous DOE reports on the topic had presented.
Climate Action Report — 2002 describes federal renewable energy programs
aimed at reducing greenhouse gas emissions.102 In Climate Change 2001: Mitigation,
the Intergovernmental Panel on Climate Change looks at the role that renewables
could play in curbing global CO2 emissions.103
Since 1988, the federal government has accelerated programs that study the
science of global climate change and has initiated programs aimed at mitigating fossil
fuel-generated CO2 and other human-generated emissions. The federal government
funds programs for renewable energy as a mitigation measure at DOE, USDA, the
Environmental Protection Agency (EPA), the Agency for International Development
(AID), and the World Bank. The latter two agencies have received funding for
renewable energy-related climate actions through Foreign Operations appropriations
Because CO2 contributes the largest greenhouse gas emission impact, the
reduction of CO2 has been the focus of studies of the potential for reducing emissions
through renewable energy and other means. Except for biofuels and biopower,
wherever renewable energy equipment displaces fossil fuel use, it will also reduce
carbon dioxide (CO2) emissions, as well as pollutants that contribute to water
pollution, acid rain, and urban smog. In general, the combustion of biomass for fuel
and power production releases CO2 at an intensity that may rival or exceed that for
natural gas. However, the growth of biomass material, which absorbs CO2, offsets
this release. Hence, net emissions occur only when combustion is based on
deforestation. In a “closed loop” system, biomass combustion is based on rotating

100 (...continued)
or other purposes, it is an example of a “no-regrets” strategy for CO2 emission reductions.
Wind and solar energy have zero CO2 emissions in operation but may need an energy
storage back-up system (such as batteries or fuel cells) that do require fossil fuel use. When
biomass is developed as an energy crop, the CO2 emissions are near zero because each new
crop absorbs the same amount of emissions as are released by combusting the previous crop.

natural gas, reduces CO2 emissions.
In the 109th Congress, more than 260 bills with provisions for renewable energy
or energy efficiency have been introduced. A general description of the renewable
energy provisions in these bills, including those enacted into law, is available in CRSth
