Lights Fluorescent lighting is more economical than incandescent lighting. Fluorescent lights use one quarter of the energy that incandescent bulbs use to produce the same amount of light.
Fluorescent lights are now available in bulbs.
Use lower-wattage bulbs in lamps and fixtures, except in cases where you need the light for reading or sewing. Place table lamps in corners for better light reflections. Set outdoor lights on photoelectric cells or clock timers. Furnaces Clean or change furnace filters frequently, dirty filters block the airflow. Also, keep the outdoor coil free of debris.
