To four hours per day lighting design, an energy-saving lamps can save 71.5 kWh of electricity a year , equivalent to 137 pounds of carbon dioxide emissions . Will ease out of incandescent play a role in global warming .
Data show that , if all of our families for the energy-saving lamps to replace incandescent , then the national total is only one annual saving home lighting , close to the annual generating capacity of the Three Gorges Reservoir. Despite such good energy-saving effect , but the new residential users to buy energy-saving lamps are not the majority , are still using incandescent old house users, but also because of the high cost of line transformation , the process is cumbersome and not willing to give up incandescent .
According to the National Development and Reform Commission Energy Research Institute Liu Hong expert analysis , an average energy saving lamp tubes containing 0.5 mg of mercury ( only a handful of brand-name products can be done about 0.25 mg ) , and 1 mg of mercury into the ground will result in about 360 tons of water pollution. Moreover, these are treated as ordinary garbage waste energy-saving lamps , most will be crushed after being transported to the landfill. These energy-saving lamps will be shattered in an instant dissemination of mercury vapors in ambient air . An ordinary energy-saving lamps can make the ambient air mercury concentration of 10 to 20 mg / cubic meter, while the mercury in the air required by the maximum allowable concentration of 0.01 mg / cubic meter.
One industry source said the cost of an energy-saving lamp recycling 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 saving lamps "rehabilitation ." "We are also engaged in free recycling charity , but it is impossible to engage in every day , because companies need to survive ." Insiders suggested that the high price of energy-saving lamps is determined by its high cost , the government in promoting green lighting, in addition to strong propaganda , but also unified procurement of quality products by the government to low-income families free gift, or subsidies for the development of production and sales of energy-saving lamps , so the price drop. It is conducive to the promotion of energy-saving lamps , but also the poor quality products out of the market . Actively develop energy-efficient mercury lamp technology and products , the implementation of mandatory recycling mechanism of energy conservation has become a major event in the fierce urgency .
