Blowing Smoke on Wind Energy
Nicolas Loris /
President Obama has been quite adamant about his push to transition to a clean energy economy, most notably by subsidizing wind and solar energy sources. He argues we need the government to invest in renewable energy to strengthen our economy and reduce the earth’s fever before it’s too late. Despite the Congress’s attempt to address the nation’s economic concerns and the government’s climate concerns, Washington’s policy prescriptions may not be all they’re cracked up to be. Consider a new study from MIT on wind power says that large wind farms could increase temperatures:
Using a climate model developed by the U.S. National Center for Atmospheric Research, the researchers simulated the aerodynamic effects of large-scale wind farms — located both on land and on the ocean — to analyze how the atmosphere, ocean and land would respond over a 60-year span.
For the land analysis, they simulated the effects of wind farms by using data about how objects similar to turbines, such as undulating hills and clumps of trees, affect surface “roughness,” or friction that can disturb wind flow. After adding this data to the model, the researchers observed that the surface air temperature over the wind farm regions increased by about one degree Celsius, which averages out to an increase of .15 degrees Celsius over the entire global surface.”
