Wind turbines, the ideal alternative to burning fossil fuels: plentiful, renewable, clean energy. Or is it?
A recent study is forcing us to take a closer look at this green energy alternative, according to ScienceDaily. Extracting energy from large-scale wind farms has the potential to warm the Continental United States by 0.24 degrees Celsius, due to the wind turbine’s redistribution of heat in the atmosphere.
At the end of the day really, all large-scale energy systems have environmental impacts. But, the ability to compare the impacts of renewable energy sources is an important step in planning a future. Extracting energy from the wind causes climatic impacts that are small compared to current projections of 21st century warming, but large compared to the effect of reducing U.S. electricity emissions to zero with solar.
