1, saving power
Pay attention to turn off the lights, and use efficient and energy-saving light bulbs. According to the estimation of the U.S. Department of Energy, replacing traditional light bulbs with energy-efficient light bulbs can reduce 400 million tons of carbon dioxide emissions. In addition to electric lights, we should also pay attention to the use of other electrical appliances, try to choose low-consumption and energy-saving products, cut off or turn off the power supply when not using electrical appliances, and keep the refrigerator frost-free.
When the weather is not very hot in summer, it is best to use fans or electric fans instead of air conditioners. When using air conditioner, don't adjust the temperature too low, just about 26℃.
2. Save water resources
Many wastewater can be recycled. The water for washing face, hands, vegetables, baths and clothes can be collected to clean the floor, flush the toilet and water the flowers. Taomi water is a good detergent, so you can stay to wash dishes and chopsticks. Pots and plates stained with oil should be cleaned with used napkins first, which is water-saving and convenient to clean, and detergent can be used less to reduce water pollution.
Step 3 save paper
The recycling of paper can prevent the landfill from releasing methane and reduce the felling of trees. According to statistics, recycling one ton of waste paper can produce 800 kilograms of recycled paper, which can reduce the felling of 17 trees. Saving paper means maintaining forest resources and environment.
4. Reduce exhaust emissions
Traffic waste gas and industrial waste gas are the main sources of domestic waste gas. Try to go out by bus or taxi, or by bike, and try to take fewer private cars. After the dregs and consumer goods in the factory were extinguished, a lot of billowing smoke filled the whole city. They should treat and filter the waste gas and then discharge it to reduce pollution.
Plants can absorb carbon dioxide and then release oxygen, so we should plant many trees, especially on the roadside.
5. Classified disposal of muck
Residue classification can recover valuable resources and reduce the energy consumption of landfill and incineration of residues. For example, waste paper is sent directly to the paper mill to consume recycled paper; Disposable commodities such as beverage bottles, cans and plastics can also be sent to related factories to become renewable resources; Household appliances can be sent to specialized manufacturers to stop synthetic recycling.
At home, we can prepare different garbage bags, collect waste paper, plastic, packaging boxes and so on. Stop daily garbage sorting and recycling, and strive to "turn waste into treasure".
Energy conservation and emission reduction can be divided into broad sense and narrow sense. Energy conservation and emission reduction in a broad sense refers to saving material and energy resources and reducing the discharge of waste and environmental hazards (including three wastes and noise). In a narrow sense, energy conservation and emission reduction refers to saving energy and reducing the emission of harmful substances in the environment.

Energy saving and emission reduction means saving energy, reducing energy consumption and reducing pollutant emissions. Energy conservation and emission reduction include two technical fields: energy conservation and emission reduction, which are both related and different. It is necessary to strengthen the application of energy-saving technologies in emission reduction projects, avoid the sharp increase of energy consumption due to one-sided pursuit of emission reduction results, and pay attention to the balance between social benefits and environmental benefits.
Energy conservation (hereinafter referred to as energy conservation) as mentioned in the Energy Conservation Law of People's Republic of China (PRC) refers to strengthening energy management, taking measures that are technically feasible, economically reasonable, environmentally and socially acceptable, reducing consumption, reducing losses and pollutant emissions, stopping waste, and effectively and reasonably utilizing energy.
China's fast-growing energy consumption and high dependence on foreign oil prompted the government to propose in early 2006 that by 20 10, the energy consumption per unit of GDP would be reduced by 20% compared with 2005, and the discharge of major pollutants would be reduced by 10%. The combination of these two indicators is what we call "energy saving and emission reduction".
Practical significance
With the rapid economic growth, China has made great achievements in various constructions, but at the same time, it has paid a huge price for the destruction of resources and environment. The contradiction between the two is becoming increasingly acute, and the masses have a strong reaction to environmental pollution. This situation is directly related to the unreasonable economic structure and growth mode. If we don't speed up the adjustment of economic structure and change the growth mode, resources can't support it, the environment can't accommodate it, the society can't afford it, and economic development can't be sustainable.
Only by adhering to economical development, clean development and safe development can we achieve sound and rapid economic development. At the same time, greenhouse gas emissions lead to global warming, which has aroused widespread concern in the international community. Further strengthening energy conservation and emission reduction is also an urgent need to cope with global climate change.
People's Republic of China (PRC) Energy Conservation Law states that "saving resources is the basic national policy of China. The state implements an energy development strategy that combines conservation with development and puts conservation first. "
