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. Besides 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 the 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 used to clean the floor, flush toilets and water flowers. Taomi water is a good detergent, which can be used to wash dishes and chopsticks. Pots and plates stained with oil should be cleaned with used napkins first, which saves water and is convenient to clean, and can also use less detergent 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 protecting forest resources and environment.
4. Reduce exhaust emissions
Traffic waste gas and industrial waste gas are the main sources of domestic waste gas. When we go out, we try to take buses or taxis. We can also ride bicycles and take private cars as little as possible. A large number of billowing smoke from the dregs of factories and consumer goods are filled in the city. They should treat and filter 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 sorting and recycling garbage every day and strive to "turn waste into treasure".
Energy conservation and emission reduction can be divided into broad sense and narrow sense. Broadly speaking, energy conservation and emission reduction 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, so as to 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 in People's Republic of China (PRC) Energy Conservation Law 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 emissions 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
The rapid economic growth in China has made great achievements in various constructions, but it has also 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 the economic structure and change the growth mode, the resources can't support it, the environment can't accommodate it, and the society can't afford it, and the economic development will be unsustainable.
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 our basic national policy. The state implements an energy development strategy that combines conservation with development and puts conservation first. "
