THE GIST
- Wind farms can warm up the surface of the land underneath them during the night.
- Satellite data of surface temperatures from western Texas show a direct correlation between night-time temperature increases and wind farm location.
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.
