In China, the primary electricity price is not uniform. The electricity price of urban residents in China is generally around 0.56~0.62 yuan per kWh; The price of industrial electricity is about 0.86~ 1.80 yuan per kwh. Different gradient electricity charges In addition, many places use different gradient electricity charges, and the electricity charges in these areas are paid according to the grade of electricity consumption.
At one time, the electricity price was not fixed. At present, many places have begun to try out the ladder electricity price, which is to determine the electricity price according to the level of electricity consumption. Let's take Beijing as an example to learn about power classification and electricity price standards:
Power classification and electricity price standard
The first gear: no more than 2 kWh, and the electricity price standard remains unchanged; For urban and rural "low-income households" and rural "five-income households", each household is set to use electricity free of charge 15 kwh per month.
The second grade electricity: the electricity between 24 1 and 400 kwh, and the electricity price standard is 0.05 yuan/kwh higher than the first grade electricity price.
Third-grade electricity: for electricity exceeding 400 kWh, the electricity price standard is higher than the first-grade electricity price by 0.3 yuan/kWh.
Power saving method
1, turn off the lights when you go out, so as to "turn off the lights when people walk".
2. The air conditioner is not lower than 26 degrees in summer and not higher than 22 degrees in winter, saving electricity and being comfortable.
3. Using more energy-saving lamps can save electricity by 70%-80%. Where 60-watt incandescent lamps are used, only about 10 watt energy-saving lamps are enough.
4. Control the number of times you open the refrigerator. Don't open the refrigerator frequently in a short time, and don't open it for a long time. Every time you turn off the refrigerator, be sure to check whether the refrigerator door is closed properly, so as to avoid wasting electricity. Let me give you a little advice: write all the items in the refrigerator on a piece of paper and cross them out every time you use them, so that you can know if there is anything you want in the refrigerator and avoid unnecessary losses.
The volume of TV and computer also determines the power consumption. Might as well turn down the sound, which not only protects the ears, but also saves electricity.
Methods of saving electricity in office
1, the office computer is set with appropriate brightness to save electricity and protect eyes.
Adjust the brightness of the computer monitor to an appropriate value. Excessive brightness of the display will not only increase power consumption, but also be detrimental to the protection of eyesight. At present, there are 300 million TV sets and tens of millions of computer monitors in China. This alone can save 5 billion kWh of electricity every year.
2. The office computer screen saver should be simple, and the monitor should be turned off in time.
The simpler the screen saver, the better. It is best not to set a screen saver. Running a huge and complicated screensaver will consume more power than when you are running normally. You can set the screen saver to None, and then set the time to turn off the monitor in the power plan. Turning off the monitor directly saves electricity than any screen saver.
3. Pay attention to the power plug of the printer.
If you don't use it after work or for a long time, you should turn off the power of the printer and its server to reduce energy consumption, and unplug it at the same time. It is estimated that this alone can reduce carbon dioxide emissions by 6.5438+0.474 million tons per year.
