Raising your air conditioner’s thermostat by 5 degrees Fahrenheit will save you about 10% on cooling costs.
During cold days and nights, set your heating thermostat to 68 degrees Fahrenheit or lower.
Clean or replace your air conditioner's filter regularly to help it run more effectively.
Use a portable or ceiling fan instead of your air conditioner. Fans cost less to run and use less energy than A/C.
Avoid using evaporative coolers or humidifiers at the same time an air conditioner is running.
Close drapes and shades to keep direct sunlight out and lower your cooling costs.
Weatherize your home by insulating, caulking, and weatherstripping to reduce both cooling and heating costs—these measures pay for themselves over time.
Compact fluorescent light bulbs last up to 10X longer than incandescent bulbs and produce less heat while using only a quarter of the electricity.
Consider unplugging electronics when they are not in use. Even when turned off, the amount of electricity still being used by electronics adds up.
Use nonessential appliances such as clothes washers and dryers during off-peak hours (before noon or after 6:00 p.m.).
Surf the Internet late at night or during early morning hours when the demand for electricity is lower.
Run swimming pool equipment for the minimum amount of time, and during off-peak hours (before noon or after 6:00 p.m.).
Dirty coils can make you refrigerator work harder than necessary. Check and clean the coils regularly according to the owner’s manual, especially during the summer.
Recycling Old Refrigerators
We recently hit an energy-efficiency milestone: a million older, inefficient refrigerators and freezers have been taken out of service and safely recycled.
