According to estimates by the United Nations Environment Program, if low-efficiency grid-connected lighting is eliminated globally with technological innovation and efficient alternatives, it will save more than 1,000 terawatt-hours (TWh) of electricity per year, equivalent to annual electricity consumption in India and the UK. The sum, which saves more than $120 billion in electricity costs per year, and reduces 530 million tons of carbon dioxide emissions.
"If we replace all the lights in China with LED lights or equipment tomorrow, the national lighting power consumption will drop by 50%, and at the same time, the cost will be saved by 50%. By replacing, we can save consumers 120 billion. These will reduce the consumption of electricity and reduce the construction of 300 new coal-fired power plants. This is not only important for China, but also for the whole world.†Kavi Zahdi, Executive Director, UNEP Regional Office for Asia and the Pacific (Kaveh Zahedi) told reporters.
To this end, the United Nations Environment Programme (UNEP)-Global Environment Facility (GEF) “Efficient Lighting Initiative†was established in 2009. The UNEP-GEF Global Efficient Lighting Partnership Program has 66 national members. These member states strongly support the goal of the Efficient Lighting Initiative to develop policies to effectively phase out inefficient incandescent lamps by the end of 2016.
According to Laura Fowler, UNEP media liaison officer, although LED lights currently do not have a unified standard on a global scale, they already have regional standards. “There are many regional organizations in the Asia-Pacific region, such as ASEAN, South Asia Group, Pacific Group, through which these organizations promote the unification of standards. China will play an important role in the formulation of standards in the Asia-Pacific region,†Laura told reporters.
LED lights undoubtedly have broad prospects in today's efficient lighting systems. According to UNEP, the performance of LED technology can be improved by about twice every two years, while the price of LED lamps continues to fall at an average rate of about 20% per year. The world's attention to LED lighting is also obvious: the 2014 Nobel Prize in Physics awarded the invention of three inventors of blue LED technology, it is the invention of this technology opened up the commercial application of LED lighting.
How should the global future promote the implementation of efficient lighting? The experts made three suggestions.
First of all, the elimination of incandescent lamps should form a synergy globally. There are more than 11 billion global incandescent bulbs produced each year, and two-thirds of incandescent lamps in China are used for export. Therefore, the elimination of incandescent lamps for efficient lighting requires global efforts.
Second, a systematic solution should be provided to drive market transformation.
Third, consider the life cycle of lighting products. “In the past, we also talked about the whole life cycle, which means that our products save electricity and save money from cost to running costs. Of course, we consider from the perspective of future development, we have to consider how to invest less resources, how to deal with them after disposal. It is necessary to reflect the green cycle and low carbon," said Lu Wenbin.
