Light your home using the same amount of light for less money. An average household spends approximately 10% of its energy budget on lighting. Switching to energy-efficient lighting is one of the fastest ways to cut your energy bills. Replacing your five most frequently used light fixtures or bulbs with models that have the ENERGY STAR, you can save $50 each year. New lighting standards and money-saving options such as halogen incandescent, CFL, and LED lightbulbs are available today.
