Google is doing an initiative called Power Meter to have people post their electricity usage online. It's a program designed to have people be hyper sensitive about what they are using and to be able to affect their bills and they drain on the grid (and the world) by turning off appliances, computers, etc.. Very cool!
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 (see sources and calculation).
At Google we're committed to helping enable a future where access to personal energy information helps everyone make smarter energy choices. To get started, we're working on a tool called Google PowerMeter which will show consumers their electricity consumption in near real-time in a secure iGoogle Gadget. We think PowerMeter will offer more useful and actionable feedback than complicated monthly paper bills that provide little detail on consumption or how to save energy.
