WHY The hot plate on most coffee makers stays on after brewing*, increasing energy use by about 25% . We will reduce energy use by turning off the coffee maker sooner. *Pod coffee makers keep water hot all the time when on, so turning them off saves energy by about 34%.
HOW After our coffee is done brewing, hit the power button on the coffee maker to turn it off. Or, unplug it. Cover the coffee pot with a lid to keep it warm longer.
