Check out this  photo of the gorgeous wind turbines I took last month at Altamont Pass, California. This is the world’s largest wind installation, with more than 4,900 turbines spread over the golden hills of CA, providing 576 MW of power. Here’s more fuel for wind and solar over nuclear:

The best ways to improve energy security, mitigate global warming and reduce the number of deaths caused by air pollution are blowing in the wind and rippling in the water, not growing on prairies or glowing inside nuclear power plants, says Mark Z. Jacobson, a professor of civil and environmental engineering at Stanford.

And “clean coal,” which involves capturing carbon emissions and sequestering them in the earth, is not clean at all, he asserts.

Jacobson has conducted the first quantitative, scientific evaluation of the proposed, major, energy-related solutions by assessing not only their potential for delivering energy for electricity and vehicles, but also their impacts on global warming, human health, energy security, water supply, space requirements, wildlife, water pollution, reliability and sustainability. His findings indicate that the options that are getting the most attention are between 25 to 1,000 times more polluting than the best available options.

“There is a lot of talk among politicians that we need a massive jobs program to pull the economy out of the current recession,” Jacobson said. “Well, putting people to work building wind turbines, solar plants, geothermal plants, electric vehicles and transmission lines would not only create jobs but would also reduce costs due to health care, crop damage and climate damage from current vehicle and electric power pollution, as well as provide the world with a truly unlimited supply of clean power.”

“Obviously, wind alone isn’t the solution,” Jacobson said. “It’s got to be a package deal, with energy also being produced by other sources such as solar, tidal, wave and geothermal power.”

During the recent presidential campaign, nuclear power and clean coal were often touted as energy solutions that should be pursued, but nuclear power and coal with carbon capture and sequestration were Jacobson’s lowest-ranked choices after biofuels. “Coal with carbon sequestration emits 60- to 110-times more carbon and air pollution than wind energy, and nuclear emits about 25-times more carbon and air pollution than wind energy,” Jacobson said.
