Everyone has a responsibility. The famous saying is to save energy.

Starting from small things in life, you can save energy in four aspects:

1. Save electricity. Be careful to turn off the lights easily and use high-efficiency energy-saving light bulbs. The U.S. Department of Energy estimates that replacing traditional light bulbs with high-efficiency energy-saving light bulbs can avoid the release of 400 million tons of carbon dioxide. Cut off or turn off the power to electrical appliances when not in use, and keep the refrigerator in a frost-free state. When the weather is not very hot in summer, it is best to use a fan or electric fan instead of an air conditioner.

2. Save water resources. Much wastewater can be recycled. The water used for washing your face, washing your hands, washing vegetables, bathing, and washing clothes can be collected to wipe the floor, flush the toilet, water the flowers, etc. Rice water is a good detergent and can be left in to wash dishes and chopsticks. Wipe oily pots and plates with used napkins first. This saves water and is convenient. You can also use less dish soap to reduce water pollution.

3. Save paper. Recycling paper avoids the release of methane from landfills and reduces the felling of trees. According to statistics, recycling one ton of waste paper can produce 800 kilograms of recycled paper, which can save 17 trees from being cut down. Saving paper means protecting forest resources and the environment.

4. Reduce exhaust emissions. Traffic exhaust gas and industrial exhaust gas are the main sources of domestic exhaust gas. When we go out, we try to take buses or taxis, or ride bicycles, and try to avoid taking private cars as much as possible. Large amounts of billowing smoke from burning garbage and producing goods in factories filled the city. They should process and filter the waste gas before discharging it to reduce pollution.
