The "How Many Legislators Does it Take to Change a Lightbulb Act" - no kidding, that's actually the name - would ban incandescent bulbs by 2012. Assemblyman Lloyd Levine, the author of the bill, told Reuters,
"Incandescent lightbulbs were first developed almost 125 years ago, and since that time they have undergone no major modifications...Meanwhile, they remain incredibly inefficient, converting only about 5 percent of the energy they receive into light."
The energy-efficient bulbs, or compact fluorescent lightbulbs (CFLs) use about 75% less energy than traditional bulbs. In fact, most of the energy used in traditional bulbs is lost as heat. About 100 million CFLs were sold in the U.S. in 2005, but that may double with Wal-Mart's plans to sell that same amount on its own in 2007.
A member of the California Energy Commission noted that an average home in California would save $40 to $50 per year if CFLs replaced all incandescent bulbs.
