Light emitting diodes (LEDs)

Lighting is one of the major purposes for which electricity is generated worldwide.

LEDs are a solid state lighting option that is even more efficient than compact fluorescent bulbs. Up to now, LEDs have had a much higher up-front cost than either incandescents or LEDs, but the technology is evolving and costs are coming down.

Here are a couple of recent articles on the technology:
