Google.org describes how the use of “smart meters” can reduce energy consumption.

If you know how much you use each day in real time, it can make a significant change to the way you use electricity without necessarily making a dent in your lifestyle.

Google outlines some sources and calculations and concludes:

Based on these figures, we get an average of 7.5 tonnes of CO2 emitted per year per household, and 4.5 tonnes of CO2 emitted per year per conventional car. So, 10% energy savings for 6 households would reduce carbon emissions by about the same amount as taking one conventional car off the road.

Google’s chart and the smart meters will only be available to selected US consumers, but I hope other countries follow suit.

This is an issue that schools (especially math classes) should investigate. Are Google’s calculations valid? How can this reduce energy consumption in your school — and home?
