Renewables are now on track to surpass coal as the largest source of electricity in the world by 2025, according to a November report from the International Energy Agency. And in the U.S., the latest outlook from the Energy Department’s Energy Information Administration is bullish on wind and solar, which along with hydropower and other renewables will surpass 20 percent of U.S. electricity generation next year, about the same level as coal or nuclear power. EIA is projecting the U.S. electric power sector will add a record 23 gigawatts of new wind capacity this year — almost double the previous record — while utility-scale solar capacity to rise by 12.8 GW in 2020, enough to power millions of homes.
