On the average sunny day, Germany’s huge energy grid gets 40 percent of its power from the sun. Guess what happened one recent morning when the sun went into eclipse. Nothing.
Or close to nothing. When the moon hid the sun for a few hours, the backup natural gas and coal plants switched on. The price of electricity rose briefly. That was it. Solar again showed itself to be a reliable energy source under a tough challenge.
Back in the United States, meanwhile, electric companies and various fossil fuel interests are fighting the American public’s growing passion for rooftop solar panels. They’re also doing battle with state laws requiring utilities to get a certain percentage of their power from renewable sources.
Oil, gas and coal lobbyists, fed by Koch brother checks, are backing a campaign by utilities to slap fees on solar panels. Their target is net metering — the system whereby homes and businesses with solar panels sell their excess electricity back to the grid.
