How much does it cost to light a typical home?
Lighting accounts for 6% of the total energy use in the average home in the United States and costs between $50 and $150 per year in electricity. Although that is not much money compared to the cost of operating heating and cooling equipment, it is enough to justify making some efficiency modifications. Also, because it is such a visible energy user, it's a good place to start teaching kids to be mindful of wasting energy.
While lighting is a relatively small part of a home's energy budget, there are several simple things you can do to keep lighting costs to a minimum.
