Winds not favourable

Turbines can increase local temperatures. OVER the years, wind turbines have been favoured as one of the most promising renewable sources of energy. But it may come at a cost. This pollution-free and environment-friendly source of energy can cause an increase in local temperatures. Researchers from University at Albany in the US, led by Liming Zhou analysed land surface temperature data of west-central Texas between 2003 and 2011 using instruments on board NASA’s Aqua and Terra satellites. The Texas region in the US has four of the world’s largest wind farms. The number of wind turbines has increased from 111 in 2003 to 2,358 in 2011. The area does not have any other developmental activities which can contribute to temperature rise. for full text: http://www.downtoearth.org.in/content/winds-not-favourable
