Standard incandescent light bulbs use more than 90% of their energy to generate heat, not light. An ENERGY STAR compact fluorescent bulb (CFL) is the most energy-efficient of all light bulbs, using 75% less energy and lasting up to 10 times longer than an incandescent bulb. Replacing an incandescent bulb with a CFL can save about $30 or more in electricity costs over the bulb's lifetime.
