Cool summer is approaching, and another peak of electricity consumption is coming, and energy conservation naturally becomes a topic that cannot be avoided. How can families save energy? Choosing energy-efficient lighting products is clearly an important tool.
Don't underestimate this small energy-saving lamp. The data shows that at present, China's lighting power accounts for about 13 of the total electricity consumption of the whole society. If all the incandescent lamps are replaced with high-efficiency lighting products, the annual electricity saving will be 48 billion kWh. If the whole society realizes the replacement of LED lighting products, it can save about 350 billion kWh per year, which is equivalent to the power generation of four Three Gorges hydropower stations.
Mr. Shen, who lives in Zaozhuang City, Shandong Province, recently renovated the house. He replaced the lights in his home with energy-saving lamps. Compared with incandescent lamps, energy-saving lamps are currently expensive. However, Mr. Shen has a small abacus in mind. Although incandescent lamps are cheap, they are easy to break. Energy-saving lamps save energy and worry, and cost recovery in a few years.
Is the fact really as Mr. Shen imagined?
Let's calculate the account: The test shows that a 5W energy-saving lamp has the same luminous efficacy as a 25W incandescent lamp, and its life is about 8 times that of an ordinary incandescent lamp. From the price point of view, the purchase of a high-quality energy-saving lamps is about 10 to 15 yuan, which is equivalent to the price of 5 to 8 incandescent lamps. However, the energy saving lamp has an illumination life of 8,000 hours, which is equivalent to the sum of eight incandescent lamps. In terms of power consumption, a 25W incandescent lamp will consume 1 kWh of electricity in 40 hours. If it is replaced with a 5W energy-saving lamp, it will consume only 0.2 kWh in 40 hours. Long-term use, or energy-saving lamps are more cost-effective, and the lighting effect is better.
From 2009 to 2013, the Green Development Project Office of the National Development and Reform Commission successively carried out energy-saving lamp donation promotion activities in 27 young and old border areas, and donated a total of 2.587 million energy-saving lamps. It is estimated that the annual energy saving will be 120 million kWh, saving electricity costs. 0.6 billion yuan.
This is just a microcosm of China's promotion of efficient lighting products in recent years. According to statistics, from 2008 to 2010, the central government invested a total of 2.562 billion yuan to promote 360 ​​million high-efficiency lighting products. These high-efficiency lighting products generate a total of approximately 66 billion kWh of electricity over the life cycle. Liu Shengping, chairman of the China Lighting Association, said that according to the electricity fee of 0.5 yuan / kWh, the central government subsidy of 1 yuan can save 13 yuan, which saves about 33.3 billion yuan in electricity expenses for the majority of urban and rural residents and large energy-saving lamps users. .
Not only that, but under the promotion of the financial subsidy promotion policy, the lighting product industry is gradually becoming more standardized. At present, green lighting products with good quality and moderate price have gradually become the mainstream of the lighting market, and the living space of counterfeit and shoddy products has been further squeezed. However, in small cities and rural areas, the promotion of green lighting products is still a weak link. Lu Fang, deputy director of the National Development and Reform Commission's Office of Energy Conservation Lamp Project Management, said frankly.
As a star of conservation in the field of lighting, energy-saving lamps are gradually becoming the mainstream choice for our living lighting with the evolution of technology, the stabilization of performance, the reduction of prices, and the changing consumer attitudes. Recently, the emerging LED lights have become the stars in the stars due to their increasingly significant power saving effect and convenient control.
Li Zhijun, chairman of Shanghai Yaming Lighting Co., Ltd. gave an example to the reporter. Yaming LEDT8 has been successfully applied to many large supermarkets in Carrefour in China, replacing the traditional T8 lamps with a system power of 40W. Each store uses about 3800. With a commercial electricity and electricity fee of 1 yuan per kWh and 18 hours of lighting per day, each store can save about 540,000 yuan in electricity per year, and the investment can be recovered in one and a half years.
Why is the energy saving effect of LED lights so outstanding? This is because only 10 of the electric energy consumed by ordinary incandescent lamps is converted into light energy, and the energy utilization rate of LED lamps can reach 90. Therefore, one 3W LED lamp and 5W energy-saving lamp, 25W incandescent lamp have The same light effect. In addition, LED lamps have an average life of 30,000 hours, which is more than 25 times that of incandescent lamps.
It should be noted that although green lighting products look beautiful, there are still many inferior products on the market. Some inferior lighting products will have obvious light decay after two or three months of use, and some products will have obvious flicker and damage to the eyes. The quality supervision department recommends that when purchasing energy-saving lighting products, it is necessary to select the products produced by regular manufacturers and look for the certification marks of the products.
By changing a light bulb and changing our way of thinking, we can change the world. Secretary-General Ban Ki-moon of the United Nations [microblogging] said. A lamp may be insignificant, but the energy gathered can not be ignored. Buying a virtue, a low-carbon life, let's start from now, start with each of us.
