People's Daily Online, March 19, according to the Hong Kong Ta Kung Pao report, global pollution is becoming more and more serious, and the low-carbon and energy-saving lifestyle is getting more and more attention. Xu Kuangdi, former president of the Chinese Academy of Engineering, who is the mayor of Shanghai, said that Hong Kong can follow the foreign practices and regulations. Private cars entering the downtown area are subject to additional fees and even a license to encourage public access to public transport to help improve air pollution. He also advocates the use of LED lighting for street lights. Take the mainland as an example. If one-third of the national lighting is LED, the annual power consumption can be equivalent to the power generated by two Three Gorges hydropower stations. When attending the Hong Kong Institution of Engineers Luncheon on the previous day, Xu was asked how Hong Kong can promote low-carbon life. It said that Hong Kong's public transport, including subways and buses, is well developed and can take advantage of this to encourage people to reduce their use of cars, such as Singapore. With the United Kingdom, it is stipulated that any private car that enters the city center must pay an additional fee. If it is to enter the downtown area every day, it is necessary to obtain a license. He estimated that Beijing and Shanghai will introduce such practices in the future, and joked that mainlanders have a typical Chinese "love face" culture. If they don't buy a car, they feel embarrassed. He thinks that they can't ban buying a car. But the culture of the car can be adjusted. He also said that the low-carbon economy must be universally involved. The Mainland has included a low-carbon economy as part of the primary and secondary school curriculum. Hong Kong can promote a low-carbon economy in citizenship. Xu Kuangdi, a famous iron and steel metallurgy expert himself, went to the University of Science and Technology yesterday to speak at the University of Science and Technology yesterday. He said that China is in a period of rapid industrialization and urbanization. The coal-based energy structure has made China's carbon dioxide emissions in the forefront of the world. There is a need to adjust the energy structure. The first step is to develop a circular economy from the traditional linear economy and develop nuclear energy. Promote a low-carbon, energy-efficient lifestyle with renewable energy. He cited Beijing Yingchuang's “BTB†(Bottle To Bottle) technology, which recycles the waste glass crucible and cleans it, then breaks it into recycled bottle-grade slices and then produces it into a glass crucible. This process can reduce the production process by 150,000 tons per year. carbon dioxide emissions. He also believes that one of the best ways to promote low-carbon life is to introduce more energy-efficient devices in buildings, such as photovoltaic solar cells. The Capital Museum basically does not need to use external power. LED lighting can also be promoted. He said that if one third of the lighting in the mainland uses LED, it can save 168 billion kWh per year, which is equivalent to the power generation of two Three Gorges hydropower stations. He believes that street lights are illuminated for ten to twelve hours a day, consume more electricity than household lighting, and are the best entry point for LED lighting.
