How Electric Vehicles Could Make or Break the Power Grid
Electric-vehicle sales have grown exponentially in recent years. Today, there are more than two dozen plug-in cars on the market, and dozens more are set to hit showrooms before the end of the decade.
That’s a positive development for reducing oil consumption, but it has mixed results for the electrical grid.
As they reach mass scale, plug-in cars could, in theory, overload local electric circuits. But if managed properly, they could also be a boon for utilities looking to sell more electricity.
