America’s Power Grid Isn’t Ready for Electric Cars - City Lab

December 10, 2018

 

Today, less than 2 percent of the vehicles Americans buy are electric. But within the next three decades, some automotive industry experts expect electric vehicles could make up the majority of U.S. and global car sales.

 

All told, American drivers log about 3 trillion miles per year, consuming more than 170 billion gallons of gasoline and diesel in the process. Converting all those road miles to electricity would place new demands on the nation’s system for producing and delivering electricity.

 

As part of a major energy infrastructure study, we are seeking to understand how an increase in electric vehicles (EVs) might change how energy is supplied and consumed. So far, we have figured out the impact of electric vehicles will depend on where you live and when they are charged.

 

Estimating how much electricity EVs will demand


Using a similar technique featured in our recent paper on hydrogen vehicles, we developed a state-by-state assessment of the amount of electricity that would be needed to charge an electrified fleet of personal cars, trucks, and SUVs.
