“The $30 billion firm, which employs some 20,000 employees, once used coal to generate electricity. But now it delivers some of the nation’s cleanest power using natural gas and renewable energy sources, such as wind, solar and geothermal energy. Nearly 70% of PG&E’s electricity comes from sources that are greenhouse-gas free.
In recent years, natural gas has surpassed coal as the leading source of electricity in the US. In 2017, natural gas accounted for nearly 32% of US power generation, up from about 22% a decade earlier, according to federal data. Coal, meanwhile, now accounts for 30%, after falling from 49% over the same time period.”
