That said, he adds that it’s not a permanent solution. A future grid that runs entirely on renewables needs to be more flexible, since operators won’t be able to burn fossil fuels to fill temporary gaps between energy demand and generation. (At night during a heat wave, for instance, people could be running lots of air conditioners, but there would be no sun to power them.)
