The theory is that if people can see how they’re wasting electricity, they’ll change their behavior. As its motto for PowerMeter, Google is using a Lord Kelvin quote: “If you cannot measure it, you cannot improve it.”

To achieve that measurement aim, the company will need the smart grid to be more developed. Utilities still need to install communicative smart meters countrywide. The manufacturers of everything from your television to your dishwasher need to design those devices to talk, or a startup has to figure out how to do the same.

But the process should go fairly quickly. President Obama is pushing the smart grid, and there’s a big chunk of money set aside for it in the stimulus bill. General Electric just ran a Super Bowl ad about the smart grid, so it has entered the popular lexicon. Industry insiders estimate that smart grid devices should be widespread by next year.
