1. Retrofit T12 lights with magnetic ballasts to T8 lights with electronic ballasts.
2. Make the swtich to compact fluorescent lights.
3. Consider removing excess fluorescent lights and installing reflectors.
4. Install motion detectors to control lighting in frequently unoccupied areas, such as restrooms and copy rooms.
5. Retrofit incandescent or fluorescent exit signs with long-lasting, low-energy LED exit signs.
6. Clean dusty diffusers and lamps every 6-12 months for improved lumen output.
7. Rewire restroom fans to operate with the lights.
8. Install separate switches for smaller areas. This way only lighting that’s needed is turned on.
9. Funding for lighting retrofits is available for community funded and non-profit organizations through the Energy Conservation Program.

1. Look for a refrigerator with automatic moisture control. Models with this feature have been engineered to prevent moisture accumulation on the cabinet exterior without the addition of a heater. This is not the same thing as an "anti-sweat" heater. Models with an anti-sweat heater will consume 5% to 10% more energy than models without this feature.
2. Don't keep your refrigerator or freezer too cold. Recommended temperatures are 1° to 3°C for the fresh food compartment of the refrigerator and -18°C for the freezer section. If you have a separate freezer for long-term storage, it should be kept at -18°C. To check refrigerator temperature, place an appliance thermometer in a glass of water in the centre of the refrigerator. Read it after 24 hours. To check the freezer temperature, place a thermometre between frozen packages. Read it after 24 hours.
3. Keep your fridge and freezer full. Surprisingly, it takes less energy to cool a full refrigerator or  freezer than an empty one, provided it is not so jammed that air can't circulate. Fill extra space with  gallon jugs of water placed  in the back of both the freezer and refrigerator. You can drink the water and use the ice in portable coolers.
4. Open the refrigerator door less. Every time the door opens, warm air rushes in. Energy must be used to cool it back down. If you're cooking, get all the refrigerated items you need for the recipe at the same time. And when you're finished with them, put them back in the refrigerator at the same time.
5. Food safety requires prompt cooling of most hot foods. Cool foods quickly in a cold water bath, or place small items directly into the refrigerator.
6. Always cover everything. Humidity escapes from uncovered foods and liquids. The compressor must work harder to remove the excess humidity.
7. The single most effective way to reduce refrigerator energy costs is to remove or unplug unnecessary refrigerators or freezers. Running a second refrigerator or freezer,particularly an older model, only makes sense when the additional cold storage is needed. Consolidate your fresh and frozen foods into one appliance and you'll see the savings.
8. Regularly defrost manual-defrost refrigerators and freezers. Frost buildup increases the amount of energy needed to keep the motor running. Don't allow frost to build up more than one quarter of an inch.
9. Make sure your refrigerator door seals are airtight. Test them by closing the door over a piece of paper or a ten dollar bill so it is half in and half out of the refrigerator.
10. Move your refrigerator out from the wall and vacuum its condenser coils once a year unless you have a "no clean" condenser model. Your refrigerator will run for shorter periods with clean coils.
11. Buy an Energy Star fridge.  Funding is available through the Energy Efficiency Incentive Program.  Funding is also available for community funded and non-profit orginizations through the Energy Conservation Program.
