Your fridge will work better, use less energy and save on energy bills. Check refrigerator seals by closing them on a piece of paper. If it pulls out easily, make a service call. If your second fridge isn't used much, pull the plug. Save the money on your electricity bill, and use less energy.
Energy efficiency cuts the emissions contributing to global warming.
Look in the window to check on what's cooking. Opening the oven door lowers the temperature, increases cooking time and wastes energy. Life will look brighter and you'll save energy. Compact fluorescent light bulbs and halogen lamps will save energy. Install 2-way switches in halls and stairways so lights can be switched off from different locations.
