Report: Repower Texas with Clean Energy
Reaping the Rewards
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.1
- Approximately 54 percent of the electricity consumed in the United States is in states with RES policies.2 States with RES programs, however, account for 75 percent of America’s renewable energy generating capacity.3
- 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.
