In an interview with reporters, Mr. Lv Qingjie, a senior engineer of Henan Electric Power Design Institute, said that in energy conservation and emission reduction, energy conservation and emission reduction of hydropower resources is the most important. As a region lacking water and electricity, Zhengzhou should start from itself and strive to achieve the festival. Water saving, energy saving and emission reduction.
Lv Qingjie has long been engaged in the supervision of hydropower energy conservation and emission reduction. She said that we cannot do without electricity in our lives. However, power plants need coal, oil, etc., and these resources are non-renewable and must save energy. After a long-term investigation, she found that the fundamental of energy conservation and emission reduction is to eliminate waste as much as possible. In this year's political association, she strongly advocated the use of energy-saving lamps. She said that instead of incandescent lamps with LED lights, the power consumption is only 1/10 of that of ordinary incandescent lamps, and the life can be extended by 100 times, and it is green. The relevant departments of the municipal government should formulate measures to require all enterprises and enterprises to use energy-saving lamps, but the price of energy-saving lamps is relatively expensive, and the government should provide certain subsidies. She specifically mentioned that street lights and shopping malls use lights, using high-power LED lights, which save 1/5 more than 250-watt high-pressure sodium lamps, if the existing lights are replaced by high-power LED lights The electricity saved is very impressive.
USB Cable :1.Type A: almost every USB cable has a standard flat rectangular interface at one end. Most computers have a usb-a port to connect to only one USB port.
2.Type-B: almost square connector for printers and other active devices connected to computers. They are not common now because most devices have been moved to smaller connections.
3.Mini USB: a smaller connector type that was standard for mobile devices before micro USB. It's not common today, but you'll see it on some cameras, PlayStation 3 controllers, MP3 players, etc.
4.Micro USB: the current standard for mobile and portable devices, even smaller than Mini USB. Although you can still find micro USB on smartphones, tablets, USB battery packs and game controllers, some have turned to usb-c
5.Type-C: the latest USB standard, which is a reversible cable, promises higher transmission speed and higher power than previous USB types. It can also take into account a variety of functions.
