According to a new report from the electricity and gas utility National Grid (which serves parts of New York and Massachusetts) found a rapid increase in electric vehicles on the city streets and highways will require upgraded power grids to handle all the new demand. By 2035, a charging station could demand as much power as a sports arena or small town.

In 2045, those large charging stations could demand upwards of 30 megawatts of capacity, with peak usage of a large manufacturing plant.
