Saving 1 kWh of electricity is equivalent to saving 5 kWh of electricity. The energy consumption of a bus is 1/7 of a taxi... Yesterday, the Chinese Academy of Engineering Dean Xu Kuangdi’s "Tianyi Forum" academician conference was held at the University of Nottingham Ningbo, China. It is pointed out that in the face of climate warming, residents' consumption behavior has a decisive influence on terminal energy consumption.
Slamming the air conditioning life of cool summer and warm winter
The popularity of air-conditioning has made people live a cool summer and warm winter life. Xu Kuangdi slammed this phenomenon.
Xu Kuangdi cited the energy consumption survey results of 25 households with similar income and education background in Zhongguancun, Beijing in 2006: the average energy consumption per unit area is 23 degrees. Surprisingly, the difference between the least energy-consuming and most households is 50. Times.
Wasted energy is not only displayed on the meter, he pointed out that only 1/4 or even 1/5 of the electricity generated by the power plant can be truly utilized by users. Using coal to generate electricity, 5 parts of energy, through conversion, transportation, to the user, only one copy left. Saving 1 kWh is equivalent to saving 5 kWh of energy.
Low-carbon life is not a hard day
Energy conservation and emission reduction does not mean that the people have to go through the days of "asceticism". It is actually a positive attitude towards life.
Xu Yudi made a comparison with several kinds of vehicles: 87% of gasoline used the loss of the engine and the loss of energy transmission. It also carries 240 people. Rail transit requires 1 unit of road resources, 2 buses are needed, and 6 private cars are needed. If you choose to take rail traffic, then one person is only 0.01 kilograms of standard coal for 1 kilometer, 0.02 kilograms of standard coal for buses, and 0.14 kilograms of standard coal for taxis.
He stressed that it is very simple to achieve a low-carbon life. From eating and sleeping to housing and traveling, low-carbon life is in front of ordinary people: use less air-conditioning; recycle waste as much as possible, classify domestic waste; replace with handkerchief Napkin; more outdoor exercise, try to use less treadmills; turn the TV screen into medium brightness; use instant messaging tools such as e-mail, use less printers, fax machines, etc.
Recommended all energy-saving lamps for street lamps in Ningbo
If you think that the new building is more energy efficient than the old building, then it is wrong. Xu Kuangdi said that the Tsinghua School, built in the 1920s and the first century, consumes 34 degrees per square meter per year, while the annual energy consumption per square meter of Shanghai Jinmao Tower is 215 degrees. It was built in 2008 at the University of Pennsylvania. The annual energy consumption per square meter of the building is as high as 356 degrees. Last year, China's building energy consumption has accounted for 24% of total energy consumption, and building energy conservation is imminent.
"China's building energy efficiency is mainly to promote energy-saving LED lights. If China's buildings use 1/3 LED lights, the annual energy savings can be equivalent to two Three Gorges hydropower stations." Xu Kuangdi said, "I suggest that Ningbo first replace all street lights with Energy-saving lamps," Xu said.
