In case you're still among the set doubting if the smart grid is really necessary, Earth2Tech has a solid post explaining how record heat (something that is going to happen a lot more often, unfortunately) is a prime example of how the smart grid can save us from the serious energy woes that occur with heat waves.
"The answer to the already stretched power grid isn't just to add more power generation, even if its clean power. It's to build out the infrastructure of the smart grid to the point where utilities have many more options fo...Read the full story on TreeHugger
