Steps

1
Analyze your utility bill to identify your average monthly kWh consumption and check for time-based electricity rates offered by your utility to shift power use to off-peak hours.
2
Replace incandescent light bulbs with LED or compact fluorescent models. For example, a standard 60 Watt bulb can be replaced by a 9 Watt LED equivalent.
3
Address 'vampire loads' by plugging electronics into advanced power strips and turning off the switch when devices are not in use, or by unplugging unused electronics entirely.
4
Improve home sealing by applying silicone or acrylic latex caulk to gaps and cracks in window and door frames to prevent air leaks.
5
Optimize your HVAC system by replacing air filters monthly and using a programmable thermostat to set temperatures lower (winter) or higher (summer) when you are asleep or away.
6
Lower the water heater temperature to 120 degrees Fahrenheit. Turn off the power to the heater, remove the panels using a Phillips #2 screwdriver, and adjust the needle.
7
Insulate the electric water heater tank. Turn off the breaker, measure the tank, wrap it in an insulating blanket, and mark/cut out areas for controls and the pressure relief valve before taping it permanently.
8
Update old appliances to ENERGY STAR certified models, such as front-loading washing machines, and operate them efficiently by running full loads with cold water.

Pro Tips

  • Keep south-facing window draperies open during the day in winter to use sunlight for heat and closed at night to reduce chills.
  • Run dishwashers and laundry late in the evening if your utility provider offers reduced off-peak rates.

When to Call a Professional

If your bill remains high after making efficiency improvements, consider a professional energy audit to identify hidden issues.
