One of the biggest criticisms against wind and solar energy has been quashed

A new analysis in Nature Energy gives renewable-energy subsidies the thumbs-up. Dev Millstein of Lawerence Berkeley National Laboratory and his colleagues find that the fossil fuels not burnt because of wind and solar energy helped avoid between 3,000 and 12,700 premature deaths in the US between 2007 and 2015.
