Google Power Meter by google.org

Google has introduced Google PowerMeter which can show consumers their electricity consumption in a secure Google gadget. Google is trying & testing this product with many utility partners in USA, India, Germany, and Canada.

According to Google

Its nearly impossible to make informed choices about electricity. This is a problem but also a huge opportunity for us all to save money and help the environment by reducing our power usage. Studies show that access to your household’s personal energy information is likely to save you 5–15% on your monthly bill. Even greater savings are possible if you use this information to see the value of retiring your old refrigerator, installing a new air conditioner or insulating your home. 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.
