I would guess more than 50% of the extra generation needed to charge cars has come from gas: marginal increases in gas generation. Marginal (where extra MWh come from) generation matters, not overall generation sources. In 2019, natural gas had the largest share (38 percent) in U.S. electricity generation, coal had the second-largest share (23 percent), and nuclear had the third largest (20 percent). For example https://www.pnas.org/doi/10.1073/pnas.2116632119 https://www.pnas.org/doi/10.1073/pnas.2116632119 “We apply our estimates to an analysis of the Biden administration’s target of having electric vehicles make up 50% of new vehicle purchases by 2030. We find that, without significant and concurrent changes to the electricity sector far more substantial than those over the last decade, the increase in electricity emissions is likely to offset more than half the emission reductions from having fewer gasoline-powered vehicles.”
