Heating Systems Work Harder in the Cold
The biggest contributor to high winter bills is the weather. The colder it is outside, the more energy it takes to heat your home - even if you don't adjust your thermostat.
This is especially true in homes that are not properly insulated. Add insulation to help reduce your heating costs.
Portable heaters may use a lot of energy too. A plug-in space heater can use up to 1,750 watts per hour. Running one 8 hours a day for 30 days will add $30.20 to your monthly electric bill.
