Energy‐Efficient Lighting

Only about 10 percent of the energy used by a regular incandescent light bulb goes toward producing light. The other 90 percent of the power is wasted as heat. In comparison, energy-efficient lights produce higher percentages of light than heat with the electricity they consume. As a result, they can provide the same amount of light as standard bulbs, using much less energy. And since lighting typically consumes about 25 percent of home’s baseload electricity use, it represents a big area for potential savings.
