Stats On Clean Renewable Energy

Filed under: Clean Renewable Energy, stats, wind — Tags: — ioconnor @ 7:27 pm

Often times I have vague impressions I’d like to pin down. Such as on clean renewable energy. (Nuclear is not clean or renewable and biofuel is not clean.) I believe I’ll start adding references as I find them to this blog entry.

  • 2009.05.08 Wind Power Increase in 2008 Exceeds 10-year Average Growth Rate

    Good article with lots of facts and links to spreadsheets. Including:

    1. World wind power grew by 29% in 2008.
    2. Wind power accounted for 42 percent of new capacity additions in USA in 2008. (Behind only natural gas.)
    3. USA wind increased overall capacity by 50 percent in 2008.
    4. Texas in 2008 is the leading state in terms of wind.

    I’m not totally confident in this report though because of statements like this which appear to not make any sense. (50% growth from 8358 would be about 4000, not 25000!): “U.S. capacity increased by 50 percent-8,358 megawatts-to 25,170 megawatts at year’s end.[7] Additions would have been even greater if not for delayed extension of the federal Production Tax Credit, which caused developers to postpone an estimated 4,000 megawatts of further additions to 2009.”. In addition their figure 3 graph of energy produced in America seems overly jagged dipping to 0 in 2000 and close to zero again in 2002 and 2004.
