The proportion of LED bulb sales in Japan exceeds 50%
Based on an average of 4 hours of lighting per day, one energy-saving lamp can save 71.5
Based on an average of 4 hours of lighting per day, one energy-saving lamp can save 71.5 kilowatt-hours of electricity a year, which is equivalent to reducing the emission of 137 kilograms of carbon dioxide. Eliminating incandescent lamps will play a certain role in alleviating global warming.
 
According to statistics, if all households in my country replace incandescent lamps with energy-saving lamps, the total annual electricity savings of only household lighting in the country will be close to the annual power generation of the Three Gorges Reservoir. Despite such good power-saving effects, not the majority of newly-built residential users purchase energy-saving lamps. Old-house users who still use incandescent lamps are also unwilling to abandon incandescent lamps due to the high cost of line renovation and cumbersome procedures.
According to analysis by Liu Hong, an expert from the Energy Research Institute of the National Development and Reform Commission, an energy-saving lamp tube contains an average of 0.5 mg of mercury (only a few ** products can achieve about 0.25 mg), and 1 mg of mercury will cause about 360 tons if it penetrates the ground. Water pollution. Not only that, most of these waste energy-saving lamps that are treated as ordinary garbage will be crushed and transported to the landfill. These energy-saving lamps will emit mercury vapor into the surrounding air when they are broken. An ordinary energy-saving lamp tube can make the mercury concentration in the surrounding air reach 10-20 mg/m3, and according to regulations, the higher allowable concentration of mercury in the air is 0.01 mg/m3.
　
An industry insider said that the recycling cost of an energy-saving lamp is 1 yuan to 2 yuan. Due to the insufficient awareness of the public, it is difficult to take the initiative to take the money for the aftermath of the energy-saving lamp. "We have also engaged in public welfare activities for free recycling, but it is impossible to do it every day, because companies also need to survive." Insiders in the industry suggested that the high price of energy-saving lamps is determined by their high cost. When the government promotes green lighting, in addition to vigorously In addition to publicity, the government can also purchase high-quality products for free to low-income families, or formulate subsidies for the production and sales of energy-saving lamps to reduce their prices. This is not only conducive to the promotion of energy-saving lamps, but also squeezes out inferior products from the market. Actively developing mercury-free energy-saving lamp technology and products, and implementing a mandatory recycling mechanism have become a hurried event in my country's energy-saving and emission-reduction work.
