Coal is the long king of America's electric grid will soon get toppled by renewable energy.
Solar and wind power are growing so rapidly that for the first time ever, the United States will likely get more power in 2021 from renewable energy than from coal, according to projections from the Institute for Energy Economic and Financial Analysis.
This milestone is being driven by the gangbusters growth for solar and wind as well as the stunning collapse of coal. And it comes as the United Nations warned on Tuesday that countries are not doing enough to keep the planet's temperature from rising to near-catastrophic levels.
