China to phase out incandescent light bulbs in 5 years

The lights are going out for incandescent bulbs, as China pledges to replace the 1 billion it uses annually with more energy efficient models within five years.

Beijing's move is a major step in efforts to improve lighting efficiency and reduce greenhouse gas emissions. Lighting accounts for 19% of electricity use worldwide, according to a 2007 estimate from the International Energy Agency, a figure that could drop to 7% if the rest of the world followed China's lead, the Global Environment Facility fund said.

The decision by the world's second largest economy to phase out incandescents follows in the footsteps of Australia, the European Union, Brazil and others.

But according to the Global Environment Facility, incandescents still make up 50-70% of worldwide sales and China's move forms a striking contrast to the US government's backsliding on the issue. This summer Republicans drove a bill through the House of Representatives stripping all funding for government enforcement of improved lighting efficiency standards, which come into force next year.

It is unclear whether China will totally phase out production of incandescents. A report from state news agency Xinhua said that "imports and sales" would be banned – seemingly implying that exports would still be allowed.

Campaigners hope China's plan will nonetheless encourage producers – who make 3.85 billion incandescent bulbs a year, an estimated 70% of the world's supply – to shift towards other products, in particular CFLs (compact fluorescent lamps) and LEDs. CFLs use around 75% less energy to produce an equivalent amount of light and last much longer.

The country has already become the largest producer of energy-efficient light bulbs, thanks in large part to sizable grants from international environmental agencies.

Experts predict that the shift in demand will also cut the cost of CFLs and increase the cost of incandescents globally.

Imports and sales of 100 watt and higher incandescent bulbs will be banned from October next year, Xie Ji, an official at the country's top economic planning body said, while those of 60 watts and above will be banned from October 2014.

The senior official added that incandescents of 15 watts or higher would be banned from 2016 if the scheme was a success.

The plan showed China's determination to save energy, cut costs and curb climate change, he went on, and would have a "significant impact" on global use.

Xie, who is deputy director of the environmental protection department with the National Development and Reform Commission, added that lighting accounts for 12% of China's total electricity use. The NDRC has estimated that the switch will save 48 billion kilowatt hours of power per year and reduce emissions of carbon dioxide by 48 million tonnes annually. China emitted 7,710 million tonnes of carbon dioxide in 2009.

Overall, China has pledged to cut energy consumption per unit of GDP by 16% and cut carbon emissions by 17% in the five years to 2015.

Yang Fuqiang, the senior advisor on climate change and energy at the US-based Natural Resources Defence Council, said the amount of electricity used by lighting in China at the moment was two or three times the generating capacity of the massive Three Gorges dam.

He added that while exports would still be legal, the plan should help companies produce more energy efficient bulbs, not least because China already had strong research and development and production capacity for energy efficient lighting.

The Global Environment Facility fund, which has invested millions of dollars in China to encourage the phase-out, says that moving to efficient lighting is one of the simplest ways for countries to cut carbon emissions.

Christophe Bahuet, the deputy country director of the United Nations Development Programme, said: "I think what's important for us is that China is joining an international trend. It also sends a signal that will inspire others."

But he cautioned that implementation would be key, warning: "It is a roadmap, but a lot will have to be done at provincial and local level to help explain why people should go for these plans."

Wang Jinsui, the president of the China Illuminating Engineering Society, told the China Daily newspaper earlier this year that it would take producers time to switch. He added that the government should consider subsidies because many families would not be able to afford the more expensive energy-efficient bulbs.

Liu Shengping, the secretary general of the China Association of Lighting Industry, told the newspaper that it was "unrealistic" to require energy efficient lights were used everywhere.

"As long as the demand exists, Chinese manufacturers can hardly pull the plug on the production line," he said.

Wikipedia : Light-Emitting Diode (LED)

The following Wikipedia entry for Light-Emitting Diodes (LEDs) is well worth reading if you would like to find out more.

A light-emitting diode (LED) is a semiconductor light source.[1] LEDs are used as indicator lamps in many devices and are increasingly used for other lighting. Introduced as a practical electronic component in 1962,[2] early LEDs emitted low-intensity red light, but modern versions are available across the visible, ultraviolet and infrared wavelengths, with very high brightness.

When a light-emitting diode is forward biased (switched on), electrons are able to recombine with electron holes within the device, releasing energy in the form of photons. This effect is called electroluminescence and the color of the light (corresponding to the energy of the photon) is determined by the energy gap of the semiconductor. LEDs are often small in area (less than 1 mm2), and integrated optical components may be used to shape its radiation pattern.[3] LEDs present many advantages over incandescent light sources including lower energy consumption, longer lifetime, improved robustness, smaller size, faster switching, and greater durability and reliability. LEDs powerful enough for room lighting are relatively expensive and require more precise current and heat management than compact fluorescent lamp sources of comparable output.

Light-emitting diodes are used in applications as diverse as replacements for aviation lighting, automotive lighting (particularly brake lamps, turn signals and indicators) as well as in traffic signals. The compact size, the possibility of narrow bandwidth, switching speed, and extreme reliability of LEDs has allowed new text and video displays and sensors to be developed, while their high switching rates are also useful in advanced communications technology. Infrared LEDs are also used in the remote control units of many commercial products including televisions, DVD players, and other domestic appliances.

Wikipedia : Compact Fluorescent Lamps

A compact fluorescent lamp (CFL; also called compact fluorescent light, energy-saving light, and compact fluorescent tube) is a fluorescent lamp designed to replace an incandescent lamp; some types fit into light fixtures formerly used for incandescent lamps.

Compared to general-service incandescent lamps giving the same amount of visible light, CFLs use less power (typically one fifth) and have a longer rated life (six to ten times average). In most countries, a CFL has a higher purchase price than an incandescent lamp, but can save over five times its purchase price in electricity costs over the lamp's lifetime.[2] Like all fluorescent lamps, CFLs contain mercury, which complicates their disposal. In many countries, governments have established recycling schemes for CFLs and glass generally.

CFLs radiate a light spectrum that is different from that of incandescent lamps. Improved phosphor formulations have improved the perceived colour of the light emitted by CFLs, such that some sources rate the best "soft white" CFLs as subjectively similar in colour to standard incandescent lamps.
