Lighting

  • Make a habit of turning off lights as you leave a room, especially in summer. Lights add a lot of heat to the room – 99% of a light’s energy use is converted to heat, 1% to light. Use only as much light as you need.
  • Keeping lights and fixtures clean can improve efficiency as much as 20%.
  • Take advantage of reflected light by placing portable fixtures near light colored walls or other surfaces.
  • Replace incandescent light bulbs in high use areas with compact fluorescent ones. They use up to 70% less energy and last up to 10 times longer.
  • Lighting accounts for about 15% of a home’s electric use. Compact fluorescent bulbs can replace the incandescent ones most commonly used. Fluorescent bulbs are more expensive, but they last 10 times longer and use 75% less electricity.
  • Consider using task lighting (lighting directed at a specific area) instead of overhead or general lighting, which may light unused areas of the room. By limiting lighting only to areas where it is needed, savings in the cost of bulbs and energy can be made.
