How much energy does your house use?Ask Google

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? 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.
Google promises to solve these issues with their new beta project dedicated to home energy monitoring. They are working on a tool called Google PowerMeter which will show consumers their electricity consumption in near real-time in a secure iGoogle Gadget. Google PowerMeter, now in prototype, will receive information from utility smart meters and energy management devices and provide anyone who signs up access to their home electricity consumption right on their iGoogle homepage. The graph below shows how someone could use this information to figure out how much energy is used by different household activites.
