The EV revolution could put a major strain on the nation’s electric grid, an aging system built for a world that runs on fossil fuels. To upgrade the grid to meet growing electricity demand, the U.S. needs to build a massive amount of new transmission and distribution lines to connect new renewable energy resources to population centers. But there are major regulatory hurdles to grid infrastructure buildout, and the government is not investing near the amount that analysts say the nation needs in order to meet its electrification targets.
