Pay attention to turn off the lights. Use efficient and energy-saving light bulbs. The U.S. Department of Energy estimates that replacing traditional light bulbs with energy-efficient light bulbs can reduce 400 million tons of carbon dioxide.
Do not switch energy-saving lamps for a short time. It is reported that energy-saving lamps actually consume the most electricity when switching.
Don't leave what you can finish during the day to do at night. Wash clothes and do homework before dark. Going to bed early and getting up early is good for health, environmental protection and energy saving.
2. Low-carbon cooking
Try to save energy in the kitchen. Cooking oil heating will produce carcinogens and fumes, polluting the living room environment. Reduce cooking and cook more vegetables. Don't fill the rice cooker and kettle too full, otherwise the soup will overflow after boiling, wasting energy, and it is easy to put out the stove fire and cause gas leakage. Adjust the combustion range of the flame so that it does not exceed the outer edge of the bottom of the pot to achieve the best heating effect. When the pot is small, the flame will burn.
3. Energy-saving use of household appliances
When buying washing machines, televisions or other electrical appliances, choose reliable low-consumption and energy-saving products.
Cut off the power supply of TV and computer in time when not in use, which not only saves electricity, but also prevents the hidden danger of fire caused by short circuit of socket. Turn off the power when the water dispenser is not in use, and keep the refrigerator frost-free.
Step 4 recycle
Reducing the recycling of materials through recycling can reduce the consumption of new raw materials, thus reducing carbon dioxide emissions. For example, recycling organic materials such as paper and cardboard can avoid methane released from landfills (a gas that causes greenhouse effect, mainly methane). According to statistics, recycling one ton of waste paper can produce 800 kilograms of recycled paper, which can cut down 17 trees, saving more than half.
Recycling plastics and metal products and reusing one kilogram of aluminum can avoid the emission of eleven kilograms of carbon dioxide.
Minimize the consumption of aluminum film packaging, Tetra Pak brick packaging and other disposable goods.
5. Save energy for heating and cooling.
Most families consume energy for heating and cooling. As long as natural ventilation is effectively used to avoid overheating in the room, the cost and carbon dioxide emission can be simply reduced by 65,438+00%.
6. Garbage sorting and disposal
Garbage sorting can recycle valuable resources and reduce the energy consumed by landfill and incineration. For example, waste paper is sent directly to a paper mill to produce recycled paper; Beverage bottles, cans and plastics can also be sent to related factories to become renewable resources; Household appliances can be sent to specialized manufacturers for decomposition and recycling. Different garbage bags can be prepared at home to collect waste paper, plastic, packaging boxes, kitchen waste and so on.
7. Economy cars
Energy-efficient cars produce less carbon dioxide per kilometer. Generally speaking, the heavier the car, the more fuel it consumes and the more carbon dioxide it produces. Compared with economical small-displacement cars, large SUVs and luxury cars emit at least twice as much carbon dioxide as the latter. Off-road vehicles have a high safety factor, but they consume a lot of fuel. The power transmission of automatic transmission car is accomplished by hydraulic pressure, which will cause power loss in work, especially when driving at low speed or parking in traffic jam.
8. Bring your own shopping bag or reuse plastic bags for shopping.
The raw materials of plastics mainly come from non-renewable mineral energy such as coal, oil and natural gas. Saving plastic bags means saving the earth's energy.
9. Buy local products
Buying local products can reduce the carbon dioxide produced during product transportation. For example, according to a report released by the Ministry of Environment, Food and Rural Affairs, in Britain, 8% of the carbon dioxide emitted by cars comes from vehicles transporting non-local products.
10. Reduce the purchase of animal foods such as meat, eggs and milk.
Raising livestock consumes more than 2/3 of cultivated land; Animal husbandry accounts for 65,438+06% of artificial methane on the earth. Meat consumes much more energy in the process of production, packaging, transportation and cooking than plant food, and plant food accounts for 25% of human behavior that causes global greenhouse effect.
1 1. Overpackaging
Pay attention to buying products with simple packaging. This means that less energy is consumed in the production process of packaging, less garbage is sent to landfills, and the economic burden of consumers is reduced.
12. Buy less unnecessary clothes
Clothing consumes a lot of energy in the process of production, processing and transportation, and at the same time produces pollutants such as waste gas and wastewater. On the premise of ensuring the needs of life, each person can save about 2.5 kilograms of standard coal and reduce carbon dioxide emissions by 6.4 kilograms. If 25 million people in China do this every year, it can save about 62,500 tons of standard coal and reduce carbon dioxide emissions by 6,543,800 tons.

"Who knows, every grain is hard", but now the phenomenon of wasting grain is still serious, wasting 0.5 Jin of grain (taking rice as an example)
For example, it can save energy by about 0. 18kg standard coal, and reduce carbon dioxide by 0.47kg correspondingly. If China reduces food waste by 0.5kg per capita every year, it can save energy by about 241000t standard coal and reduce carbon dioxide by 612000t every year.
14. Reduce the waste of livestock products
If each person wastes less than 0.5 kg of pork every year, it can save energy by about 0.28 kg of standard coal and reduce carbon dioxide by 0.7 kg. If the average person wastes less than 0.5 kg of pork every year, it can save about 353,000 tons of standard coal and reduce carbon dioxide emissions by 9 1. 1.000 tons.
15. Reduce smoking
Smoking is harmful to health, and cigarette production consumes energy. If 1 day smokes less 1 cigarette, each person can save about 0. 14 kg of standard coal, and correspondingly reduce 0.37 kg of carbon dioxide. If all the 350 million smokers in China do this, they can save about 50,000 tons of standard coal and reduce CO2 1.3 million tons every year.
That's about it.
