When your refrigerator runs or your AC turns on, some power plant or wind-farm or solar plant somewhere will increase their power output to supply the power your device needs. WattTime can determine which energy provider will increase output to supply your need, and so can determine if extra power you use a given moment will come from a renewable or high-carbon-emissions source. This information changes very often (on the order of every five minutes) so having a real-time service like WattTime to inform your devices WHEN to use power can allow you to use the same amount of electricity but dramatically reduce your carbon footprint!
