Save Energy and Money with More Efficient Lighting
The average household dedicates about 5% of its energy budget to lighting every year, with much of the cost owing to the few lights that are on the most. Switching those frequently used bulbs to light-emitting diodes (LEDs) is a great place to start. Find the 10 lights you use most, and the lights you use at least one hour per day, and make the change.
