A new scheme to promote sustainable energy from Google. PowerMeter monitors electronic and electrical devices (computers, refrigerators, washing machines, lamps and etc.) and registers our daily, weekly and monthly consumption of electricity while providing us with suggestions on how to reduce our use of energy. These data are then shared with other users over the Internet in a sort of contest to see who cave the most. The system is still in prototype phase undergoing tests but will soon be made available firstly in the USA, Germany and the UK.
