Beijing Review - After 130 years of using incandescent lamps, China is determined to abandon the energy-guzzling bulbs in favor of more energy-efficient ones.

On November 1, the Development and Reform Commission (NDRC) and five other government departments jointly released a joint circular, vowing to gradually halt imports and sales of the traditional incandescent lamps.

Those lamps are widely used for both household and commercial lighting. Electricity is used to heat up the thin wire filament inside the bulb until it glows and produces light. Unfortunately, while incandescent bulbs are effective at illuminating even the darkest of spaces, they are not energy efficient. Much of the electricity is used to make heat, and light is only a by-product.

In 1882, China's first incandescent lamp was used in Shanghai, providing a more reliable alternative to oil lamps and candles. In the past 130 years, China has become the world's largest producer and consumer of incandescent bulbs. In 2010, the country's output of such bulbs stood at 3.85 billion, with sales hitting 1.07 billion yuan ($168.47 million).

As China embarks on a greener path of development, it is aiming to phase out these less efficient bulbs.

"This move is part of the government's vigorous efforts to push forward energy conservation and emission reduction," said Xie Ji, Deputy Director of Resource Conservation and Environment Protection under the NDRC.

The effort to replace incandescent lamps with energy-efficient ones nationwide will help save 48 billion kwh of electricity and reduce 48 million tons of carbon dioxide emission annually, said Xie.

"This year marks the beginning of the 12th Five-year Plan (2011-15), which is focused on economic rebalancing. Meanwhile, the United Nations Climate Change Conference is about to convene in Durban, South Africa," said Xie. "Against this background, China is taking swift action to propel green lighting and implementing effective measures in response to climate change."
