A new study from Harvard University indicates that while wind energy provides long-term advantages over natural gas and coal, the renewable is not as clean as previously thought. Findings show that large-scale wind deployments require more land than accounted for by initial studies. Early findings also failed to identify turbine-caused temperature increases.
So while wind has already outpaced solar as America’s go-to renewable, solar’s environmental impact is ten times less than that of its blustery counterpart.
The study’s authors warn that this information should not be taken as a case against wind energy. “Rather, the work should be seen as a first step in getting more serious about assessing these impacts for all renewables.”
