Wind farms causing warming

    The problem with playing favorites when it comes to economically unsustainable technologies.

    New research finds that wind farms actually warm up the surface of the land underneath them during the night, a phenomena that could put a damper on efforts to expand wind energy as a green energy solution.

    Researchers used satellite data from 2003 to 2011 to examine surface temperatures across as wide swath of west Texas, which has built four of the world's largest wind farms. The data showed a direct correlation between night-time temperatures increases of 0.72 degrees C (1.3 degrees F) and the placement of the farms.

    "Given the present installed capacity and the projected growth in installation of wind farms across the world, I feel that wind farms, if spatially large enough, might have noticeable impacts on local to regional meteorology," Liming Zhou, associate professor at the State University of New York, Albany and author of the paper published April 29 in Nature Climate Change said in an e-mail to Discovery News.

    This is something the designers (engineers) expected. It is proviable by basic thermodynamics. The turbines aid in mixing of the air from the surface to approximately thee heights of the turbins tower length.

    How do I know? I own a Texas wind turbine farm. What is the ideal location for a wind farm if there were only sufficient wind? The Florida citrus groves. The grower would lose less fruit in a sudden drop in temperature in early spring.

    ...except that frost damage happens on still mornings when there is no wind. That's why we (well, those who can afford them) pay big bucks for motorized wind machines in the orchards.

    I want to live in the middle of a wind farm so it won't be so cold at night.
