Clean lighting fixtures regularly. Dust on lamps, reflectors and light bulbs impairs lighting efficiency. Locate floor, table and wall lamps in the corner of a room rather than against a flat wall. Lamps in corners reflect light from two wall surfaces instead of one, and therefore, give you more light. Choose light colors for walls, ceilings, floors and furniture.
Light colors reflect light.
Dark colors absorb light and require higher bulb wattages. It takes almost as much electricity to run a small load as it does a full one. Set the water selector on your washer to warm or cold for most loads. Very few loads require hot water for washing. Tests indicate that cold-water detergents thoroughly clean most fabrics in warm or cold water with considerable savings on the energy required for water heating.
