Executive Summary
Renewable energy in the United States is on the rise. America
now generates twice as much electricity from the wind and the sun as we did
just four years ago, and 2007 promises to be another year of record growth.
The renewable energy boom is the result of a series of
federal and state policies designed to promote cleaner sources of electricity,
as well as technological improvements that have reduced the cost of renewable
energy over the last three decades, rising fossil fuel prices, and increased
concern about global warming.
Renewable electricity standards (RES), which require
increasing percentages of the electricity supplied to consumers to come from
renewable resources, have been among the most important factors in encouraging
the development of renewable energy.
Twenty-five states and the District of Columbia have adopted an RES.
And while many of those policies are in their infancy, RES states have already
begun to reap the benefits in increased renewable energy development, reduced
pollution, cost savings and economic growth.
The 25 states that have adopted an RES are leading the
nation in renewable energy development.
- Approximately
54 percent of the electricity consumed in the United States is in states
with RES policies. States with RES programs, however, account for 75
percent of America’s
renewable energy generating capacity.
- In
2006, more than two-thirds of all new renewable electric generating
capacity in the United
States was built in RES states. The
same is likely to hold true in 2007, with more than 70 percent of planned
renewable generation capacity expected to be built in RES states. (RES
policies also spur renewable energy development in nearby states, while
some renewable energy built in RES states is spurred by other public
policies.)
- Renewable
energy will make up a larger proportion of new power generation in RES
states in 2007 than in states without RES policies. In 2007, renewable
electricity generators account for about 38 percent of planned capacity
additions in RES states, compared to just 12 percent in non-RES states.
- Of the
top 20 utilities with long-term contracts for wind power in the United States,
17 of them are covered in whole or in part by RES policies.
- While
many public policies have contributed to the growth of renewable energy,
the RES has played an important role. The U.S. Department of Energy
estimates that RES policies contributed to the construction of about half
of the wind energy added in the United States between 2001 and
2006, with the share increasing to 60 percent in 2006.
State RES policies are reducing pollution and saving natural
resources.
- Renewable
energy sources built after the adoption of state RES policies reduce America’s global warming emissions by
approximately 8.4 million metric tons per year, the equivalent of taking
more than 1.5 million cars off America’s roads.
- Renewable
generators in RES states also produce fewer emissions of health
threatening pollutants that contribute to the formation of smog and soot
than fossil fuel generators. Renewable energy, therefore, can reduce the
overall cost of complying with federal limits on these pollutants and make
it more possible to set tighter limits that are more protective of human
health in the future.
- Renewable
generators in RES states also save vast amounts of water—approximately 1.2
billion gallons per year.
Renewable energy development in RES states is boosting local
economies.
- Over
the last two years, several of the world’s leading manufacturers of wind
turbines and solar panels have either built new manufacturing facilities
or expanded existing facilities in the United States. RES policies
play an important role in luring manufacturing facilities, as they
represent a long-term commitment to build the market for renewable energy
technologies. Colorado, Pennsylvania,
Oregon, Texas,
and Massachusetts
are among the RES states that have experienced increases in renewable
energy manufacturing activity in recent years.
- Renewable
energy development in RES states has had ripple effects that extend across
the nation. Increased demand for renewable energy creates increased demand
for raw materials, construction, accounting, engineering and a wide
variety of services. While the benefits of renewable energy are strongest
in local economies near manufacturing facilities and renewable energy
installations, every state in the nation has at least one business that
participates in the renewable energy economy and benefits from its growth.
- Renewable
energy has had particular benefits for rural economies. Texas
landowners, for example, now receive an estimated $9.5 million in royalty
payments from wind farm operators, while one town in rural Colorado saw its
tax base increase by 29 percent as a result of a wind farm development
there.
State RES policies also have the potential to save
electricity consumers money.
- A 2007
analysis by the energy research firm, Wood MacKenzie estimated that
adoption of a 15 percent federal renewable electricity standard would save
more than $100 billion in electricity costs by 2026, largely by driving
down the cost of natural gas.
- In
many states, such as Colorado and Washington, wind farms have proven to be
the least-cost source of electricity, especially when all the likely
future costs of fossil fuel-fired power plants are included (such as the
risk of energy price spikes and the future cost of carbon dioxide
emissions).
- Solar
power, while currently more expensive than other forms of power
generation, can play an important role in reducing demand for power at
peak periods, when it is most expensive.
- Renewable
energy development reduces upward pressure on natural gas prices.
- A 2005
study by researchers at the Lawrence Berkeley National Laboratory
estimated that the 18 state RES policies then in effect would produce
savings of approximately $10 billion in lower natural gas bills as a
result of reduced demand for natural gas.
Adoption of a national RES would increase the benefits of
renewable energy to the environment and the economy.
- The United States should adopt a renewable
electricity standard that calls for 25 percent of America’s
electricity to come from new renewable sources by 2025.
- States
that have not yet adopted RES policies should consider doing so, while
those that have adopted RES policies should consider strengthening them by
increasing the required percentage of renewable energy, excluding
nonrenewable or polluting energy sources, and refining their policies to
ensure that renewable energy targets are met.
- The
state and federal governments should also adopt complementary policies to hasten the deployment of
renewable energy along with policies to improve the energy efficiency of
the American economy.
