I. Small, office-efficient techniques
1. Scientificly rational use of computers: displays should be selected appropriately because the larger the monitors, the more energy they consume. Computers replace screen protection with stand-by: running large and complex screens may be more power-consuming than you are running properly. Lcd screens replace c°ft screens: lcd screens are about 50% energy-efficient compared to the traditional crt screens and can save about 20 degrees per year each, correspondingly reducing co2 by 19. 2 kg. Lowering the brightness of the computer screen: lowering the brightness of the computer screen by saving about 30 degrees per desktop per year and correspondingly reducing co2 by 29 kg: about 15 degrees per laptop per year and correspondingly 14. 6 kg。
2. Scientificly rational use of printers, photocopiers: timely power outages: printers and their servers should be shut down at work hours or long hours to reduce energy consumption, while plugs will be removed. This alone is estimated to reduce co2 emissions by 1. 474 million tons per year. Printer sharing can reduce equipment idle, increase efficiency and save energy. Use draft mode, printer saves ink: when printing an unofficial script, the standard printing mode can be changed to a draft printer mode。
3. When personnel leave the office, turn off lighting, air conditioning, office equipment:
4. Close the doors and windows when turning on the air conditioner. The temperature of the air conditioner in the summer is 26 degrees and the temperature of the air conditioner in the winter is 18 degrees:
5. For temporarily unused interfaces and equipment, such as serials, simultaneous and infrared interfaces, wireless network cards, etc., office computers may be disabled in bos or the equipment manager, thus reducing loads and power usage, after which plugs shall be removed:
The temperature in the air conditioning office will last for some time after the air conditioner has been closed 20 minutes before work。
7. The promotion of e-offices will not only reduce paper consumption, but also reduce transaction time and increase office efficiency。
Ii. The energy-saving approach to family life
8. Bring their own lunches with portable, environmentally friendly meals, without one-off dishes. Homemade juice not only reduces industrial water and electricity use in health。
9. Carrying their own water cups, whether out or at work, is convenient and hygienic。
10. Appropriately adjust television brightness to increase the life of the television while saving energy
11. Reduction in the time available for home appliances has had a significant effect。
12. The best way to reduce energy consumption of computers and monitors is to turn off the devices and reduce the energy consumption of the stand-by machines
13. The more refrigerators open, the more electricity is consumed. When refrigerators are used, if some ice is produced in parallel with frozen food in the freezer room, the ice is packed in containers and placed in the freezer room, which reduces the start-up time of the refrigerator compressor and achieves electricity efficiency. When refrigerators are used, the food that needs to be unfrozen in the freezer room can be removed one day in advance and released into the freezer room, which can also reduce the temperature in the freezer room and achieve electricity conservation。
14. Choose a double-key toilet. Water-efficient view
15. Small voltage car fuel savings have a high effect. Each car has its own economic speed, with the lowest fuel consumption at that speed。
The fuel consumed by vehicles in general is more fuel consumed than fuel consumed by re-starting. Therefore, if parking is longer, the engine should be shut down. A three-to-five-minute empty engine fuel consumption allows vehicles to travel about 1 km. When driving, every effort should be made to avoid sudden acceleration and deceleration, since a sudden acceleration in fuel consumption is 20 more and low speed is the most expensive, so that the car slot is as high as possible. In fact, when the speed of the car is above 85 km/hour, more fuel is consumed by air resistance (wind resistance) than by air conditioning systems when windows are opened. Promote cycling and low-carbon fitness。
When the amount of light is equal, energy-efficient fluorescent lamps not only save 75 to 80 per cent of electricity compared to incandescent lamps。
Water will be less expensive than direct flushing。
18. After filling the water with a cup, it is only 0. 5 litres of water needed to turn off the tap and brush its teeth, and 45 litres of water is wasted if the tap is opened for five minutes. Rice-water can be used to wash dishes or dishes, and rice-water after washing can be used to water flowers, and recycling can save water. Residual tea can be used to wipe furniture。
When bathing for showers and shampoo, the taps are turned off and a bath saves 60 litres of water. Reduce pollution of rivers and oceans using degradable, low-use washing products。
Households use electro-thermal drinking water machines, which keep electricity high for long periods of time, and traditional vacuum bottles with a good temperature-preservation effect and save electricity。
A single-sum plastic bag takes 600 years to decompose。
22. The timely removal of chargers after charging reduces waste of electricity。
