How much wind energy do we use in America right now?

    The best data I could find is from 2007 when there was over 12,000 megawatts of installed wind compasity. Looking at the chart though the increase over the last decades has been so steep that I’d estimate it’s probably topping 14,000 by now.

    Here’s some more on this: During the first half of 2008, the United States, for the first time, generated more wind energy electricity than Germany, despite the fact that the smaller European country still has more turbines than we do.

    Germany has enough turbines to collect about 22,000 to 23,000 megawatts of power, while the United States has a capacity of about 18,000 megawatts, Swisher said.

    “The difference is that because the winds are so much stronger here in the U.S. we are actually providing more wind-generated electricity than Germany,” Swisher told LiveScience. “Our turbines are so much more productive that theirs.”

    Though we are winning the race in terms of volume of wind energy produced, we are far behind when it comes to the proportion of our total energy we get from wind.

    While wind currently supplies about 1.2 percent of the United States’ power, it accounts for about 7 percent of Germany’s total energy consumption. And the even-smaller country of Denmark gets roughly 20 percent of its energy form wind.

    1.2 percent of the total we produce (4,157 million megawatthours (MWh)) would be 49.884 million megawatt hours)   so I don’t know — this figure sounds way too high! — I’m not even going to try to convert this… see below:

    wiki has us at the top now to confirm what was stated above:

    these are the figures for 2009!:

    1     United States   33,170
    2     Germany      25,000 [51]
    3     China     22,500
    4     Spain       18,119

    And I found this quote:

    U.S. wind power capacity now exceeds 18,302 MW which is enough to serve 4.5 million average households —- this figure was from 2007

    so we’re definitely well above 20,000 now!

    As of the end of 2010, the U.S. had roughly 40 gigawatts of installed wind capacity. Assuming a 30% average capacity factor, this fleet of 40 gigawatts will produce some 105 billion kilowatt-hours of clean, carbon-free electricity each year. By comparison, the U.S. consumes between 10 and 11 billion kilowatt-hours every day, so all wind farms currently installed in the U.S. put together provide for around 2.7% of the country’s total electricity demand.

    Notably, China now holds the global lead for wind power installations with over 42 gigawatts installed by the year’s end, having overtaken the U.S. in the course of installing over 16 GW of new capacity.
