3. Take Control of Temperature
•Set Your Thermostat: In winter, set your thermostat to 68 degrees or less during the daytime, and 55 degrees before going to sleep (or when you're away for the day). During the summer, set thermostats to 78 degrees or more.
•Use Sunlight Wisely: During the heating season, leave shades and blinds open on sunny days, but close them at night to reduce the amount of heat lost through windows. Close shades and blinds during the summer or when the air conditioner is in use or will be in use later in the day.
•Set the Thermostat on Your Water Heater: Put your water heater thermostat between 120 and 130 degrees. Higher setpoints will increase your utility bill and could result in water that scalds your fingers.
