Check Out Energy Savings with a Kill A Watt monitor from your library

Energy Trust and local libraries are making Kill A Watt® monitors available for check-out. Kill A Watt monitors measure the energy usage of household appliances and electronics. By finding out how much energy your electric devices are using, and then making energy-saving adjustments, you can take charge of your electricity use and lower utility costs year-round.
