Find what drives your Groton Dept of Utilities 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.
