New Energy Economy Emerging in the United States

As fossil fuel prices rise, as oil insecurity deepens, and as concerns about climate change cast a shadow over the future of coal, a new energy economy is emerging in the United States. The old energy economy, fueled by oil, coal and natural gas, is being replaced by one powered by wind, solar and geothermal energy. The transition is moving at a pace and on a scale that we could not have imagined even a year ago. 

Consider Texas. Long the leading oil-producing state, it is now also the leading generator of electricity from wind, having overtaken California two years ago. Texas now has nearly 6,000 megawatts of wind-generating capacity online and a staggering 39,000 megawatts in the construction and planning stages. When all this is completed, Texas will have 45,000 megawatts of wind-generating capacity (think 45 coal-fired power plants). This will more than satisfy the residential needs of the state’s 24 million people, enabling Texas to feed electricity to nearby states such as Louisiana and Mississippi.

After Texas and California, the other leaders among the 30 states with commercial-scale wind farms are Iowa, Minnesota, Washington, and Colorado. And other states are emerging as wind superpowers. Clipper Windpower and BP are teaming up to build the 5,050-megawatt Titan wind farm, the world’s largest, in eastern South Dakota. Already under development, Titan will generate five times as much electricity as the state’s 780,000 residents currently use. This project includes building a transmission line along an abandoned rail line across Iowa, feeding electricity into Illinois and the country’s industrial heartland.

Colorado billionaire Philip Anschutz is developing a 2,000-megawatt wind farm in south central Wyoming. He already has secured the rights to build a 900-mile high-voltage transmission line to California. With this investment, the door will be opened to developing scores of huge wind farms in Wyoming, a wind-rich state with few people. Another transmission line under development will run north-south, linking eastern Wyoming’s wind resources with the fast-growing Colorado cities of Fort Collins, Denver and Colorado Springs. Wind-rich Kansas and Oklahoma are looking to build a transmission line to the U.S. Southeast to export their wealth of cheap wind energy.

California is developing a 4,500-megawatt wind farm complex in the Tehachapi Mountains northwest of Los Angeles. In the east, Maine — a wind energy newcomer — is planning to develop 3,000 megawatts of wind-generating capacity, far more than the state’s 1.3 million residents need. Further south, Delaware is planning an offshore wind farm of up to 600 megawatts, which could satisfy half of the state’s residential electricity needs. New York State, which has 700 megawatts of wind-generating capacity, plans to add another 8,000 megawatts, with most of the power being generated by winds coming off Lake Erie and Lake Ontario. And soon Oregon will nearly double its wind generating capacity with a 900-megawatt wind farm in the wind-rich Columbia River Gorge.
