Other Voices -- Howard A. Learner: Quiet Revolution in Energy Efficiency to Help Solve Global Warming Problems
Today’s incandescent light bulbs will be replaced largely by compact fluorescent lamps over the next five years. The European Union is phasing out incandescent bulbs. Many manufacturers will soon stop marketing traditional bulbs here. CFLs use 75% less electricity to achieve the same amount of illumination, and they last longer. This one market transformation alone can reduce the St. Louis region’s overall electricity demand by about 10%.
• Super-efficient light-emitting diodes are coming into the market. They are far more efficient than incandescent bulbs, last longer than CFLs and can produce light in any color. LEDs are now marketed as a high-end product, but prices will be falling.
