Tips for Lowering Your Bill in Wilmington
No matter what rate you pay, the biggest savings come from the biggest consumers. Heating and cooling account for nearly half the average electric bill, so start there.
- Set your thermostat to 68F in winter and 78F in summer. Each degree of adjustment saves about 3-5% on heating/cooling costs.
- Check your HVAC filter monthly. A dirty filter makes the system work harder, costing you $5-$15/month in wasted electricity.
- If your water heater is set above 120F, lower it. Each 10-degree reduction saves 3-5% on water heating costs.
- Switch any remaining incandescent bulbs to LED. Each bulb saves about $7/year.
