Google PowerMeter is a free electricity usage monitoring tool that provides consumers with information on how much energy their home is consuming. Google PowerMeter receives information from utility smart meters and in-home energy management devices and visualizes this information on iGoogle. Studies show that being able to see ones electricity usage in near real time, throughout the day, makes it easier to reduce it and save money. This sort of feedback requires either an advanced electricity meter, a “smart meter” or a consumer-owned electricity management device, and many of today’s smart meters don’t display information to the consumer.
