The average U.S. home contains 40 light sockets, by switching to energy-saving light bulbs you can cut down on energy costs by replacing Conventional Incandescent Light Bulbs with Compact Fluorescent Lights (CFL) or Light Emitting Diodes (LED). The upfront cost for CFLs and LEDs is generally higher, but over the life of the product CFLs and LEDs are cheaper to run in the long term and use less energy to generate the same lighting.
