Ways to save energy

Starting from the small things in life, we can save energy from four aspects.

First, save electricity. Pay attention to turn off the lights when you leave, and you can 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. Turn off or turn off the power supply when the appliances are not in use, while the refrigerator remains frost-free. When the weather is not very hot in summer, it is best to use fans or electric fans instead of air conditioners.

Second, 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 saves water and is convenient to clean. You can also use less detergent to reduce water pollution.

Third, save paper. The recycling of paper can avoid methane released by landfill 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 is to protect forest resources and the environment.

Fourth, reduce tail gas 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. The city is filled with smoke from burning garbage and goods produced by factories. They should treat and filter the waste gas and then discharge it to reduce pollution.

Measures to save energy-Earth Hour.

The "Earth Hour" event was first held in Sydney, Australia at 8: 30 pm on March 3, 2007. That night, more than 2.2 million families and businesses in Sydney turned off their lights and appliances for an hour. According to statistics afterwards, the electricity saved by turning off the lights for one hour is enough for 200,000 TVs to run 1 hour and 50,000 cars to run 1 hour. Many participating citizens reported that the stars they could see that night were several times more than usual.

Subsequently, from this limited scale, "Earth Hour" swept the world at an alarming rate. Only one year later, the "Earth Hour" has been recognized as one of the biggest global actions to deal with climate change, and has become a global and sustainable activity.
