Wind Energy Use to Jump, Then Soar

May 13, 2008 -- Two decades from now Americans could get as much electricity from windmills as from nuclear power plants, according to a government report that lays out a possible plan for wind energy growth.

The report, a collaboration between the Energy Department research labs and industry, concludes wind energy could generate 20 percent of the nation's electricity by 2030, about the same share now produced by nuclear reactors.

Such growth would pose a number of major challenges but is achievable without the need of major new technological breakthroughs, said the report released Monday.

"The report indicates that we can do this nationally for less than half a cent per kilowatt hour if we have the vision," said Andrew Karsner, the Energy Department's assistant secretary for efficiency and renewable energy.

If achieved, it would be an astounding leap.

Wind energy today accounts for only about 1 percent of the nation's electricity, although the industry has been on a growth binge with a 45 percent jump in production last year.

To reach the 20 percent production level, wind turbines would have to produce 300,000 megawatts of power, compared to about 16,000 megawatts generated today. Such growth would envision more than 75,000 new wind turbines, many of them larger than those operating today. About 54,000 megawatts would be produced by turbines in offshore waters.

And it would require a major expansion of the electricity grid system to move power from high-wind areas to other parts of the country, the report said.
