Recently, the Japanese government announced the early termination of the three-month power-saving measures. In response to the weakening of power supply caused by the earthquake, tsunami and nuclear power plant crisis, Japan began to restrict electricity use in some areas since July 1. Nowadays, the power-saving order can be cancelled in advance, and Japanese companies and residents can be said to have contributed. According to the Japanese government's investigation, after the Great East Japan Earthquake, Tokyo and surrounding areas were short of electricity by more than 10%, and the northeastern region lacked electricity by nearly 8%. Even the unaffected Osaka and the central and southern regions suffered from electricity shortages of around 4%. To this end, the Japanese government has set clear energy-saving targets: 15% of electricity needs to be saved in Tokyo and the Tohoku region, 10% in Osaka and Kansai, and mandatory power-saving requirements for companies with large electricity consumption. . For companies and businesses that use a lot of electricity, 15% of the goal of saving electricity is not a small problem. Some large shopping malls have carried out a series of energy-saving measures after careful analysis of daily electricity consumption: installing inductive lighting in corridors and passages with fewer customers; reducing the brightness of the bathroom lighting; adjusting elevator operation according to passenger flow. In order to reduce air conditioning, Mitsubishi Electric has put a light-proof film on the glass. Toshiba and other companies have changed all the lights into LED energy-saving lamps, which can save more than 10% of electricity. Although residential electricity is not subject to mandatory power cuts, the Government still appeals to the public to actively cooperate. As a result, spontaneous civil energy-saving activities have quietly emerged. Fukui Shinshiro, who lives in the suburbs of Tokyo, planted bitter gourd outside his home window. The bitter melon vines quickly climbed over the western walls and windows and became a "green curtain." She found that “green curtains†brought coolness to the interior and the interior felt cool. So, she sent this idea to the Internet. In just a few days, the hit rate exceeded 100,000. The activity of planting “green curtains†was unacceptable, so that the bitter melon seeds in Tokyo were out of stock. Now walking on the streets of Tokyo, many buildings are covered with vines of bitter gourd, loofah or other plants. Research by the Tokyo Institute of Technology professor Nishinomiya shows that "green curtains" can reduce wall temperatures by 9% to 12%, and indoor temperatures by 1.3% to 1.7%. The “Power Saving Wisdom Group†consisting of several housewives is very active in Yokohama City and has now expanded to hundreds of people. They ponder every day to save electricity and communicate with each other online, such as air conditioning new tricks, buy blackout curtains to lower the room temperature, put the wet towel into the refrigerator and wipe the face. They also put together various ideas and distributed them to the public free of charge. In the Shinagawa area of ​​Tokyo, Hiroshi Shizuoka launched the “Reduction of Meter Amperesâ€, and first reduced the amperage of the appliance from 80 to 60 and then to 30. He found that as long as different types of appliances are used at different times, the ampere can be greatly reduced. The event quickly responded, and users who asked power companies to reduce their amps in the past few months have increased fivefold. The situation of power shortages has also made power-saving products come into being. This summer, a new "energy-saving suit" is selling well because it can make the temperature of the body drop drastically, even if it is sitting in a high temperature room. A company invented a cool towel with special materials, and it would feel very cool to sweat with this towel under the scorching sun. Nippon Electric Co., Ltd. has developed a computer power management system that helps the computer automatically save power and display power saving effects on the screen. According to the company, companies with more than 1,000 computers can save more than 30% of their electricity every year. The Japanese government recently announced that 15% of its energy-saving goals have been met. The electricity saving of 31,000 residents in Tokyo even reached 28%, far exceeding the government's 15% requirement. Although the current official power saving requirements have been abolished, folk energy-saving activities are still continuing, and energy-saving is becoming a way of life for Japanese residents.
