Google has announced the Google PowerMeter, a program that displays real-time information about home energy consumption on your computer  The program is in closed beta right now, but Google hopes that it will eventually be distributed to anyone who has a smart meter.

From the Google web page:

How much does it cost to leave your TV on all day? What about turning your air conditioning 1 degree cooler? Which uses more power every month — your fridge or your dishwasher? Is your household more or less energy efficient than similar homes in your neighborhood?

Our lack of knowledge about our own energy usage is a huge problem, but also a huge opportunity for us all to save money and fight global warming by reducing our power usage. Studies show that access to your household’s personal energy information is likely to save you between 5–15% on your monthly bill, and the potential impact of large numbers of people achieving similar efficiencies is even more exciting. For every six households that save 10% on electricity, for instance, we reduce carbon emissions as much as taking one conventional car off the road.
