"How many legislators does it take to change a light bulb?" It may sound like one of those "How many..." jokes, but it's actually a proposed title for an act. The "How Many Legislators Does It Take to Change a Light Bulb" Act is focused on attempting to lower greenhouse gas emissions and combat global warming. But perhaps the real question should be: how many legislators will change a light bulb? One will, for sure: California Assemblyman Lloyd Levine is aiming to ban incandescent light bulbs by 2012. Probably because Uh-nold says so.

So the 125-year-old invention from ol' Thomas Edison is now considered an energy waste, only converting 5% of the power it actually consumes into light. Fluorescent light bulbs is the way to go, and the compact Fluorescent light bulbs (or CFLs) only consume 25% of the power consumed by ordinary light bulbs. They also tend to last longer, fit into any fixture and provide brighter light in some cases.

Levine is the same Democrat from Van Nuys, Los Angeles who introduced a bill last year that requires most grocery stores to have plastic bag recycling. The bill is expected to become law this July.
