The average residential electric bill is based on the amount of electricity used during each billing period. By reducing energy use, most households can lower monthly electric bills.

Many members can reduce their electricity costs by applying simple energy-saving practices and making efficiency improvements.

Note: Average residential electric usage is typically divided into the following categories:

• Heating and air conditioning — approximately 45%
• Lighting, cooking, and appliances — approximately 34%
• Water heating — approximately 13%
• Refrigeration — approximately 8%

Heating and cooling account for the largest portion of your home’s energy use. Making small adjustments to your HVAC system can help reduce energy consumption and lower your electric bill.

• Set your thermostat to 78°F for cooling. Each degree cooler can increase energy use by about 8%.
• Set your thermostat to 68°F for heating. Each degree warmer increases energy use by approximately 6%.
• Only heat or cool your home when it is occupied. Adjust settings when you leave and reset when you return.
• Check thermostat accuracy by comparing it with a separate thermometer.
• Replace air filters regularly, typically once a month.
• Schedule HVAC maintenance once or twice a year.
• Inspect ductwork for leaks and proper insulation.
• Ensure your attic has adequate insulation. DOE recommends R-49 for this region.
• Check doors and windows for air leaks and seal gaps.
• Keep vents and interior doors open for proper airflow.
• Turn off ceiling fans when leaving the room.
• Choose a higher SEER rating when replacing your system for better efficiency.
