More than 300 solar projects in the United States have been canceled or delayed in recent weeks because of an investigation by the Commerce Department.
One of the nation's biggest solar-energy companies said on Wednesday that it would double production in the United States by opening a third plant in Ohio by the middle of 2023.
Major energy companies, including the largest U.S. nuclear power generator, are putting millions of dollars into a new political campaign to push for a tax on carbon dioxide emissions - a measure President Donald Trump has said he opposes.
