Buy a Better Bulb
Compact fluorescent light bulbs (called CFLs) require 75% less energy than traditional (officially called incandescent) light bulbs, and last up to 10 times longer. Be sure to look for CFLs with the Energy Star label, since these bulbs won't have any buzzing or humming problems. These bulbs now come in smaller sizes (called subcompacts) that can fit into any lamp, and they have a wider color spectrum. Replacing just four well-used 100-watt incandescent bulbs with equivalent 23-watt CFLs will save you $108 over three years. (for equivalent wattages see table below)
