Turn out the lights on traditional incandescent bulbs.
A little-noticed provision of the energy bill, which is expected to become law, phases out the 125-year-old bulb in the next four to 12 years in favor of a new generation of energy-efficient lights that will cost consumers more but return their investment in a few months.
The new devices include current products such as compact fluorescents and halogens, as well as emerging products such as light-emitting diodes and energy-saving incandescent bulbs.
"This will get us in line with the rest of the advanced industrial world in moving toward more efficient lighting," says Sen. Jeff Bingaman, D-N.M., chairman of the Senate energy committee and author of the Senate measure requiring the tougher standards.
The energy bill passed the Senate last week and is expected to clear the House this week. President Bush has said he will sign it.
