Over at Environment 360, an impressive account of wind's US potential has just gone up. In the article, you'll find information on the hurdles currently facing wind; a history of renewable energy opposition in our federal legislature; and an economic consideration: 120,000 wind and solar jobs, and 19$ billion, will disappear if the renewable energy tax credits are ushered out of existence this year.
In NC, there are a lot of financial incentives to invest in greener technologies. The clean(er, relatively) energy sector stands to become a large piece of our economic pie: solar fields across the state, wind in the mountains and off the coast, etc. One hopes that federal legislators will have the wherewithal to recognize the opportunity to keep a good thing going, eg. the renewable energy tax credits, which should be extended, not used as a political wedge issue in an election year.
