Incandescent light bulbs are about to become a thing of the past. By 2014, incandescent bulbs will not be sold in the US. Compact Fluorescent Lightbulbs (CFLs) and LED bulbs have been proven much more efficient and cost-effective.
CFLs are currently more popular because of the low cost. The current drawback is that they’re slightly more expensive than incandescent bulbs, and take 1 second to warm up. (If they take longer, you may want to contact an electrician because a longer delay is abnormal.) CFLs are now available in a wide variety of sizes, so start looking for them in your favorite hardware store.
LEDs are more expensive, but have been adopted for car headlights. They produce a clearer light, and are often included in rechargeable flashlights because they’re so efficient.
Congress estimates that, in the 15 years following the phase-out, consumers will save roughly $40 billion, and America will need 14 fewer coal fired power plants. –EcoGeek
