Wind farms have been tipped as the solution to global warming، but a new study suggests they could actually heat the planet up، as the Daily Mail said.
A study found that the US would warm a few tenths of a degree if the number of turbines were increased dramatically.
Researchers say they’ll require much more land than previously thought، needing five to 20 times more space than earlier studies have suggested.
And، persistent gusts created by vast fields of turbines could mix the normal layers of warm and cool air in a way that makes the surface toastier.
Despite the potential drawbacks، however، the researchers argue wind energy still makes more sense for the environment than fossil fuels. Study coauthor and Harvard University scientist Professor David Keith argued that، when it comes to energy production، 'there is no free lunch.'
'Wind beats coal by any environmental measure، but that doesn't mean that its impacts are negligible،' he said.
'We must quickly transition away from fossil fuels to stop carbon emissions.
'In doing so، we must make choices between various low-carbon technologies، all of which have some social and environmental impacts.'
