We came across this a while ago and are finally getting around to posting about it - a piece in Matter that asks a valid question: will the power grid be able to handle the age of the plug-in car?

And the conclusion is well, that depends. Factors such as where you live and how rapidly new technology evolves will answer this question down the line. In the end…

Because plug-in hybrids hold great promise in making transportation more affordable and sustainable, consumers will likely be lining up to buy the vehicles when they arrive, as long as they’re priced right. Widespread adoption, however, requires careful planning to minimize their impact on the power grid.
