Energy conservation is the effort made to reduce the consumption of energy by using less of an energy service. This can be achieved either by using energy more efficiently (using less energy for a constant service) or by reducing the amount of service used (for example, by driving less). Energy conservation is a part of the concept of Eco-sufficiency

1. Make sure your air conditioning and heating units are ENERGY STAR models.

2. Set a non-ENERGY STAR air conditioning unit to “Quiet Guard” or “Power Save” mode.

3. Get a programmable thermostat that will automatically turn your AC and heater on or off to save on energy.

4. Always keep windows and doors tightly shut when running the AC or heater.

5. If you have central AC, close the air vents in unused rooms to avoid cooling or heating unused spaces.

6. Turn off kitchen or bath exhaust fans as soon as possible.

7. Use ceiling fans to cool a room instead of turning on the AC.
