California ranks first among the 50 states in its capacity of solar energy, and ties for first with Nevada in the percentage its in-state, solar power generation, while ranking fourth in wind power. Texas, meanwhile, leads the nation in wind power production.
Coal, which generated more than half of U.S. electricity in 2000, produced 30 percent last year, about the same as the year before. According to government projections, by 2035 renewable sources will outstrip coal in electric power generation.
“We’ve seen the administration take a pretty anti-clean energy approach,” said NRDC energy analyst Amanda Levin. Even so, she said, “we continue to see growth in wind and solar due to the economics of clean energy as well as state and corporate interest in investing in and promoting clean energy.”
In his election campaign and since taking office, Trump has called for a coal comeback. “We have ended the war on American energy – and we have ended the war on beautiful, clean coal,” he declared in late January in his State of the Union speech. A week earlier, Trump carried through with a threat to impose 30 percent tariffs on solar cell imports. The administration also has started moving to repeal the U.S. Clean Power Plan, which is designed to cut carbon dioxide emitted by power generators.
Analysts say the impact of those moves will be softened by market forces and state government actions. “A lot of the reductions in emissions that we’ve seen over the last five years or so are due to state policies, but most important is the cheap price of natural gas and the rapidly falling cost of renewables,” said Raymond Kopp, an energy and climate specialist at Resources for the Future, a Washington-based think tank.
Twenty-nine states have adopted standards requiring utilities to meet targets for increased reliance on renewable fuels. California, for example, plans to get at least 33 percent of its power from renewable sources by 2020, 40 percent by 2024 and 50 percent by 2030.
Moreover, the nation’s coal-powered electric plants are aging and increasingly being shuttered. According to the U.S. Energy Information Administration, the number of operating coal plants declined from 616 in 2006 to 381 in 2016. In the first year of the Trump administration, nearly 30 more of the remaining coal plants were retired.
In a sign of the times, employment in the solar industry now dwarf jobs in the coal industry. Coal industry jobsactually increased about 1,000 nationwide in 2017, to roughly 52,000, according to federal Mine Safety and Health Administration data. Meanwhile, despite a small dip in 2017, solar jobs totaled 250,271, according to The Solar Foundation, a nonprofit that promotes solar technologies.
The NRDC said the U.S. should generate at least 80 percent of its electricity from renewable resources by 2050 to achieve the goals of the Paris climate accord, but the latest government forecast projects that the nation will be only at the 40 percent level by then. Last year, Trump announced plans to pull the U.S.out of the global agreement, which is intended to combat global warming by cutting greenhouse gas emissions.
