New efficiency standards for light bulbs result in the phasing out of inefficient incandescent light bulbs. The average incandescent uses about 75-100 watts whereas the average compact fluorescent light bulb (CFL) uses 15-25 watts. Clearly CFLs are more efficient, and since they last six times longer than incandescent bulbs they don’t need to be replaced nearly as often and are therefore more cost efficient. However, some believe that this efficiency standard undermines the free market and limits people’s constitutional freedoms and choices. Basically, it is illegal to sell inefficient incandescent light bulbs and so people who prefer to waste energy are not allowed to buy their preferred light bulb, and this is seen as a violation of personal liberties. But I would argue that if they really prefer the light quality of an incandescent over a CFL, they can still actually buy incandescent bulbs that are more efficient (use less energy). Or they can buy LEDs or efficient halogen bulbs. Opponents may also argue that incandescent bulb producers might be hit hard by this policy and that jobs would be at risk, but the big light bulb companies like General Electric and Phillips produce incandescent light bulbs, CFLs, LEDs, etc. Additional arguments involve the mercury content in CFLs, but this amount is so little it is harmless; coal-electricity production actually emits more mercury into the environment than CFLs. The more CFLs there are installed across the country, the less electricity is needed to light our homes and businesses. Improving end-source efficiency could solve our energy crisis by dramatically decreasing our energy consumption, and it can all start with screwing in an efficient light bulb.
