This review implied if people have a detailed understanding of their home energy use, they may find ways to save energy and lower electricity bills. Organizing the world’s information and make it universally accessible and useful is Google's mission and they believe consumers have a right to detailed information about their home electricity use. Google announced a software tool called PowerMeter which shows consumers their home energy information almost in real time right on their computer in May 2009 .
Meanwhile, A company residents in the Houston area called CenterPoint Energy launched a pilot project on home energy use in fall of 2010 , and announced the results of this project on July 25, 2011. Currently, CenterPoint Energy has installed nearly 1.5 million smart meters in its 2.2 million meter system. The company is scheduled to complete deployment in mid 2012 . This project is called In-Home Display pilot to evaluate in-house display (IHD) among 300 customers. A IHD is a small human-machine interface with a LCD display, it communicates wirelessly with smart meters and shows customers their electricity use in near real-time. In addition, it can show consumers a forecast of their monthly usage and bill. The result of this pilot showed that most participants have taken steps to adjust their energy usage. The most common steps they took to adjust energy usage are turning off lights and adjusting thermostat, and they plan to purchase energy star appliances and sealing air leaks in future .
After two years endeavor, Google announced PowerMeter was retired on September 16, 2011 . The main reason is the White House announced a goal of giving all consumers access to their energy usage in computer-friendly formats as part of a national plan for modernizing the electricity grid in June 2011 .
