Cree Sees China, Low-Cost LEDs Lighting Up Business

A nation of 1.3 billion people needs a lot of light bulbs — and a lot of energy to power them. That's why officials in China have developed a plan to increase the use of light-emitting diode (LED) technology to help light its buildings, factories and homes. LEDs require much less power than traditional lighting sources. Officials in China hope that by expanding use of the technology, the country will cut energy costs and reduce greenhouse gas emissions.
