New Study Suggests Wind Farms Can Cause Climate Change

nachiketas writes "A study led by Liming Zhou, Research Associate Professor at the Department of Atmospheric and Environmental Sciences at the University of New York concludes that large wind farms could noticeably impact local weather patterns. According to Professor Zhou: 'While converting wind's kinetic energy into electricity, wind turbines modify surface-atmosphere exchanges and transfer of energy, momentum, mass and moisture within the atmosphere. These changes, if spatially large enough, might have noticeable impacts on local to regional weather and climate.'"

  1. Local impact = climate change? by gtall · · Score: 5, Insightful

    Who wrote that headline and how can we make him stop writing new ones.

      You missed asphalt ... which absorbs heat during the day and slowly radiates it at night, completely altering local weather in and near large cities.

  2. Of course they can. by matthewmacleod · · Score: 5, Insightful

    Modifying wind patterns will very obviously have an effect on local climate. Local is the key word - these guys are talking about and increase of under one degree, directly above those wind farms, and it seems likely that this is caused by the small amounts of turbulence generated by the turbines.

    Now, if evidence emerges that this is harmful in some way, then we should of course evaluate that and make sure we understand the effects. However, I think stating "Wind Farms Can Cause Climate Change" is clearly intended to sensationalise this research and attract page views - especially given The Telegraph's well-known rabid-anti-environmentalism (they're especially anti-wind-turbine.)

  3. Duh, removal of enegy from enviro affects enviro by RichMan · · Score: 5, Insightful

    Any removal of energy from the environment wlll affect the environment.

    Solar energy capture reduces ground heating. Hyrdo capture reduces errosion and soil redistribution. Wind capture reduces winds and associated head and moisture distribution. Wave energy capture reduces shore errosion and fine particlate distribution. Tide capture does really really small scale stuff to the earth-moon-sun relationship.

    You don't get anything for free. The question is what do we accept as side effects of the energy extraction.

    The Sun only provides so much energy and that energy is what make the Earth run.

    Well, the Sun as well as the Moon's tidal forces which cause the Earth to flex by approx 30cm daily causing friction in the Earth while also massaging the crust to help relieve pressure.

    Well, that and the previous star(s) that blew up and who's energy is present in the matter and angular momentum preserved in the forming of our solar system.
    You could very well also argue that if we continue using energy at this rate, we'll also accelerate the Heat Death of the Universe.
