Washington County’s Extension office is inviting area residents to see how much energy specific appliances in their homes use. The agency has partnered with the Iowa Energy Center to provide a meter that measures voltage, amperage, wattage, run time and total kilowatt-hours of electricity being consumed. The device works by plugging it in to any household outlet, and then plugging a 12 volt appliance into the meter. The extension has the devices for Washington County residents to check out free of charge for a one week period of time.
