Once you’ve measured, how do you save?
- Lighting: switch to CFLs, which use less than 25% as much power.
- For some appliances, such as refrigerators, get a more efficient, Energy Star-rated model.
- You can use many devices more efficiently: for example, open the refrigerator door less often, let your hair or clothing partly air dry, turn down your space heater.
