Your Utility Bill
Keeping a close eye on your home energy usage makes good sense. The easiest way to determine your average energy use is to take a look at your utility bill. Most utilities will show your consumption history over the previous months and this will give you an idea of how much energy you use.
Whole Home Energy Device
If you want to determine the biggest energy loads in your home, there is a whole home energy device that can be installed that can help you narrow down each device’s energy use. If you live in Vermont, Efficiency Vermont offers a $199 discount for the Sense Energy Monitor — a valuable insight into your home energy usage.
