A Texas Wind Boom:

Wind power is on the rise in the United States, even if offshore projects continue to have a difficult time (see, e.g. Cape Wind). The New York Times reports:

Wind turbines were once a marginal form of electrical generation. But amid rising concern about greenhouse gases from coal-burning power plants, wind power is booming. Installed wind capacity in the United States grew 45 percent last year, albeit from a small base, and a comparable increase is expected this year.

At growth rates like that, experts said, wind power could eventually make an important contribution to the nation's electrical supply. It already supplies about 1 percent of American electricity, powering the equivalent of 4.5 million homes. Environmental advocates contend it could eventually hit 20 percent, as has already happened in Denmark. Energy consultants say that 5 to 7 percent is a more realistic goal in this country.

The United States recently overtook Spain as the world's second-largest wind power market, after Germany, with $9 billion invested last year. A recent study by Emerging Energy Research, a consulting firm in Cambridge, Mass., projected $65 billion in investment from 2007 to 2015.

Despite the attraction of wind as a nearly pollution-free power source, it does have limitations. Though the gap is closing, electricity from wind remains costlier than that generated from fossil fuels. Moreover, wind power is intermittent and unpredictable, and the hottest days, when electricity is needed most, are usually not windy.

The turbines are getting bigger and their blades can kill birds and bats. Aesthetic and wildlife issues have led to opposition emerging around the country, particularly in coastal areas like Cape Cod. Some opposition in Texas has cropped up as well, including lawsuits to halt wind farms that were thought to be eyesores or harmful to wetlands.

But the opposition has been limited, and has done little to slow the rapid growth of wind power in Texas. Some Texans see the sleek new turbines as a welcome change in the landscape.
