Electric car infrastructure does not exist

This Scientific American article discusses something I and others have been saying for years--the 100 year old electric grid we use for residential and business power was not designed for electric cars, which have extremely high amperage power draws. It is not so much that the grid can't handle one or two electric cars in a neighborhood; it can, and the load is not much different than things like welders or potter's kilns. But the grid was not designed for say 35% of residential homes plugging in their electric cars every evening at 5:30, at the very same time that residential electric use already peaks.

Part of the solution is broadband. Resilient, reliable fiber broadband connections to every home will enable electric providers to talk to home power controllers. The home power controllers will have enough smarts to turn the car charging on and off at the direction of the power company so that the load is balanced throughout the night, when electricity costs the least to generate.

That's right--broadband is part of the energy independence solution.
