> There will be significant additional load on the Electric grid. True, but people will be charging their cars most often when they're asleep, so it's less of an impact on peak load. It may be more of a base load/duty cycle impact. However, even then, this type of load is also easily interruptible and automatically controlled by modern hardware. This makes it more serviceable with renewable power, more easy to make price-sensitive, and more able to provide demand response. (Potentially to the extent of being able to put power back into the grid and act as a negative load.) (That said, the original idea of a household outlet is a stretch... I understand charging a Tesla at 120V/15A to be glacially slow.)
