The United States is on track to produce more electricity this year from renewable power than from coal for the first time on record, new government projections show, a transformation partly driven by the coronavirus pandemic, with profound implications in the fight against climate change.

It is a milestone that seemed all but unthinkable a decade ago, when coal was so dominant that it provided nearly half the nation's electricity. And it comes despite the Trump administration's three-year push to try to revive the ailing industry by weakening pollution rules on coal-burning power plants.

Those efforts, however, failed to halt the powerful economic forces that have led electric utilities to retire hundreds of aging coal plants since 2010 and run their remaining plants less frequently. The cost of building large wind farms has declined more than 40% in that time, while solar costs have dropped more than 80%. And the price of natural gas, a cleaner-burning alternative to coal, has fallen to historic lows as a result of the fracking boom.

Now the coronavirus outbreak is pushing coal producers into their deepest crisis yet. As factories, retailers, restaurants and office buildings have shut down nationwide to slow the spread of the coronavirus, demand for electricity has fallen sharply. And, because coal plants often cost more to operate than gas plants or renewables, many utilities are cutting back on coal power first in response.

In just the first four and a half months of this year, America's fleet of wind turbines, solar panels and hydroelectric dams have produced more electricity than coal on 90 separate days — shattering last year's record of 38 days for the entire year. On May 1 in Texas, wind power alone supplied nearly three times as much electricity as coal did.

The latest report from the Energy Information Administration estimates that America's total coal consumption will fall by nearly one-quarter this year, and coal plants are expected to provide just 19% of the nation's electricity, dropping for the first time below both nuclear power and renewable power, a category that includes wind, solar, hydroelectric dams, geothermal and biomass. Natural gas plants, which supply 38% of the nation's power, are expected to hold their output steady thanks to low fuel prices.
