Turn lights off when not in use. Replace all light fixtures and bulbs that operate four or more hours a day with ones that use fluorescent bulbs to save money and energy. Let Mother Nature light your home.
Sunlight is brighter than a multitude of light bulbs, and it's free.
Put timers on a few lights in your home, and install motion detectors on exterior lights. Use a microwave or toaster oven to cook small portions of food and a conventional oven or stovetop for larger items. Turn off TV's, VCRs, cable boxes, CD players, cassette decks and computers during long periods of non-use. This will cut costs and increase the life of the product.
