Greener LEDs might give the energy-saving light bulbs a brig

LED light bulbs can reportedly save more than 80 percent on energy use. But with the pending ban on incandescent light bulbs and Americans' increasing adoption of energy-saving light bulbs, consumers are getting greedier for greener alternatives - and that can be a good thing for both electric bills and the environment.

Now, MIT's Technology Review reports that a new approach to fabricating LED lights might increase their efficiency by an additional 20 percent. Moreover, the new manufacturing method could result in higher quality light than existing LED lights offer.

Sound too good to be true? Here's how it works.

Researchers at the National Renewable Energy Laboratory in Golden, Colorado, have made a new yellow-green LED that can combine with other colors to make white light. The new LED would cut out some of the inefficiencies in the LED process currently used to make white lights.

This would help make the new LEDs the most energy-efficient lighting technology available - with respect to both production and consumption. Osram says that current LED bulbs need less than 2 percent of their energy consumption for their manufacture. Just when you thought it couldn't get greener...
