Wind farms can change the weather, according to a model of how these forests of giant turbines interact with the local atmosphere. And the idea is backed up by observations from real wind farms.......
How such a change might affect local wildlife and agriculture is not clear.
The findings are backed by real observations. Neil Kelley, a meteorologist at the National Renewable Energy Laboratory in Golden, Colorado, has gathered data from a wind farm in California.
“Although the wind farm was more dense and the turbines smaller we still found that the turbines tended to pull down heat and momentum from above, particularly during the night-time hours,” he says.
Baidya Roy says it may be possible to modify the wind turbines so that their effect on the weather is not so extreme. “If engineers can reduce turbulence then the turbine would become more efficient and the environmental impact would be reduced,” he says.
But no amount of engineering will change the fact that energy is being removed from the wind. “People tend to think that renewable energy is for free, but it isn’t. There is a price to pay for all kinds of consumption, including renewable energy,” says Baidya Roy.

Sorry BJ but 2 degrees? You've got to move further north to realize how small 2 deg. actually is.
Cape Wind will reduce energy costs in several ways including offsetting the burning of expensive fossil fuels, reducing New England’s dependence on natural gas, and reducing the cost of compliance with the Renewable Energy Portfolio Standards (RPS) for Massachusetts electricity consumers.
There have been many ironies attached to this project, not the least of which has been the motivations behind those who oppose it: It's the wealthy vs. everyone else. Karl Marx may be largely discredited, but some of what he observed was correct: Economic class matters. How else can one explain Democratic powerhouse Ted Kennedy allying
himself with Republican Gov. Mitt Romney [related, bio] to oppose the plan?
BOSTON - The Conservation Law Foundation has called on Gov. Mitt Romney and Sen. Edward Kennedy to reconsider their opposition to the Cape Wind project in light of favorable findings in a draft environmental impact statement released yesterday.
THERE IS a "think globally, act locally" rightness to the fact that the
environmental report for the Cape Wind power project came on the same day scientists laid out the dramatic effects global warming is having on the Arctic. The report on Cape Wind's 130-turbine proposal finds few costs to marine or bird life that might outweigh the project's benefits to both the environment and the economy.
