Find what drives your Potomac Electric Power bill
Rates and averages explain the price of a kilowatt-hour, not how many you use. A plug-in energy meter logs what one corded 120 V appliance really draws over a week. A whole-home monitor logs every circuit at once, so the biggest loads on your own bill show up by name — its sensors clip on inside the panel, which is work for an electrician if that isn't you.
