2) "Here are some proven ways to reduce energy costs:
Set your thermostat at 68°F in winter, 78°F in summer. Then adjust the settings as needed. Every degree you're able to "dial back" saves from 2-3 percent on heating and cooling energy.
In summer, avoid adding heat and humidity to your home during the daytime hours. Schedule cooking, laundry and bathing in the early morning or late evening.
Open south, east and west curtains in winter for auxiliary solar heat. Close them in the summer.
Have your heat pump, furnace and central or room air conditioner tuned up prior to each heating and cooling season.
Clean or replace filters monthly. Make sure the outdoor condensing unit for your central air conditioner, window air conditioner or heat pump is clean and unobstructed.
If your home will be unoccupied for more than two or three hours, reset your thermostat to 80°F in summer, 60°F in winter. Or, add an automatic setback thermostat to control both your heating and cooling systems while you're away from home.
Avoid operating your heating/cooling system fan continuously. While constantly circulating air may feel more comfortable, the small benefit may be offset by an increase in your electric bill.
"Tighten" your home with insulation, caulking and weatherstripping.
As older appliances wear out, especially heating and cooling equipment, replace them with new higher efficiency models."
