The chief executive of the world’s largest private coal company sat before a group of U.S. lawmakers who wanted to know whether the fuel had a future. He didn’t hesitate. “Coal,” he said, “is the future.”
Not quite. This April, for the first time ever, renewable energy supplied more power to America’s grid than coal—the clearest sign yet that solar and wind can now go head-to-head with fossil fuels. In two-thirds of the world, they’ve become the cheapest forms of power.
Solar and wind will power half the globe by 2050, based on BloombergNEF forecasts. By that time, coal and nuclear will have all but disappeared in the U.S., forced out by cheaper renewables and natural gas.
