“If you cannot measure it, you cannot improve it.” — Lord Kelvin
Google and GE are working together on this tool to create a monitoring platform for home power usage. This is what Google have to say in this regard,
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.
You’ll see this tool in action is through a secure iGoogle gadget that will let you safely and privately browse your home electricity usage.
