Biden Offers Ambitious Blueprint for Solar Energy

The Biden administration on Wednesday released a blueprint for producing almost half of the nation's electricity from the sun by 2050 -- something that would require the country to double the amount of solar energy installed every year over the next four years and then double it again by 2030. From a report: The expansion of solar energy is part of President Biden's effort to fight climate change, but there would be little historical precedent for increasing solar energy, which contributed less than 4 percent of the country's electricity last year, that quickly. Such a large increase, laid out in an Energy Department report, is in line with what most climate scientists say is needed to stave off the worst effects of global warming. It would require a vast transformation in technology, the energy industry and the way people live.

The Energy Department said its calculations showed that solar panels had fallen so much in cost that they could produce 40 percent of the country's electricity by 2035 -- enough to power all American homes -- and 45 percent by 2050. Getting there will mean trillions of dollars in investments by homeowners, businesses and the government. The electric grid -- built for hulking coal, natural gas and nuclear power plants -- would have to be almost completely remade with the addition of batteries, transmission lines and other technologies that can soak up electricity when the sun is shining and to send it from one corner of the country to another.
