Power on for 3 minutes before use, so that the temperature of the electric iron is just right.

Second, heating water with steam electric iron can save electricity and time.

Thirdly, the nylon and polyester fabrics with lower temperature should be ironed first, and then the cotton, linen and wool fabrics with higher temperature should be ironed.

Four, every time ironing clothes, to remove fabric wrinkles shall prevail, not ironing for too long. Once silk or chemical fiber clothes are heated, the wrinkles disappear, so the best way is to unplug them, cut off the power supply and iron them with waste heat.

5. When buying an electric iron, choose one that can adjust the temperature. High power is better than low power. It is recommended to buy a 500-watt or 700-watt temperature-regulating electric iron. This kind of electric iron heats up quickly, and automatically turns off the power when it meets the use requirements, which not only saves electricity, but also ensures the ironing quality and saves time.

Electric fan:

First of all, the power consumption of the electric fan is directly proportional to the rotating speed of the fan blades. If the air volume meets the use requirements, try to use mid-range or low-range. For example, a 400 mm electric fan consumes 60 watts when using fast gear and only 40 watts when using slow gear, which can save one third of electricity.

Second, the floor fan and desk fan should be placed in a relatively cool place indoors to blow the cool wind to high temperature. It should be placed in the corner of the house during the day to make the indoor air flow outward; Move to the door of the window at night and blow the outdoor air into the room. If the indoor natural air flows smoothly, it is best to adjust the fan angle according to the wind direction. In addition, well-maintained electric fans can save electricity; Electric fans with oil shortage, deformed blades and easy vibration consume electricity.

Lighting:

First of all, fluorescent lamps save more electricity than incandescent lamps. The brightness of 20-watt fluorescent lamp is even better than that of 40-watt incandescent lamp. LED fluorescent lamp is a good environmental protection and energy-saving product at present. It can replace 40-watt incandescent lamp with 2 watts, and replace 20-watt ordinary fluorescent lamp and 20-watt ordinary energy-saving lamp with 4 watts.

80% energy-saving LED energy-saving lamp. Second, the installation height should be appropriate. For example, a 20-watt fluorescent lamp with a height of 1 meter has an illumination of 60 lux; 0.8 meters high is 93.75 lux. Lowering the height properly can reduce the wattage and save electricity. (At present, some businesses of LED can do it. If it is installed 2 meters high, the illumination will be around 200 lux; 3 meters high, about 96200 lux). Using LED lighting products is very useful for saving energy.

Third, make full use of reflection and introspection. Lighting can be improved if the lamp is equipped with a suitable reflector. Using the reflection of indoor wall and white wall, the illuminance can also be improved by about 20%.

Four, stairs, corridors, toilets and other places can be installed with automatic control switches, you can turn off the lights at any time, and try to choose small-capacity light bulbs.

Audio-visual household appliances:

First, the power transformer in the tape recorder is generally installed in front of the switch, and the power plug should be unplugged in time after each use; Otherwise, even if the switch on the tape recorder is turned off, the power transformer is still on, and the no-load current on the line not only wastes electric energy, but also sometimes causes disaster.

Second, don't turn on the brightness of the TV set too much when using it, which not only saves energy, but also prolongs the service life.

Microwave oven:

First, when using the microwave oven, add a layer of plastic film to the food, so that the moisture in the processed food is not easy to evaporate, which is delicious and saves electricity.

Second, frozen food should not be thawed in the microwave oven as far as possible, and it can be thawed slowly in the freezer in advance.

Others:

1. Soak the washed rice in a pot for 30 minutes and then cook it with warm or hot water, which can save electricity by 30%.

Second, the energy consumption of household appliances during standby accounts for about 10% of the total household electricity consumption, so the power supply should be cut off when the appliances are not in use.

Refrigerator:

First of all, always clear the frost in the storage room and freezer. Too thick frost will produce great thermal resistance and increase power consumption. Don't store food too full, let cold air convection, and keep the temperature balance in the box; Hot food should be cooled to room temperature before being put into the refrigerator; The temperature adjustment gear in the refrigerator should be moderate and cannot be set to strong cooling, so as to avoid increasing the power consumption of the refrigeration cycle system in the refrigerator due to the increase of workload.

Second, the dropper above the water tray of the refrigerator is the only channel for direct exchange between the refrigerator and the outside air, so the phenomenon of cold leakage cannot be ignored. If you wrap a ball of cotton on the drip bucket and then wrap it with string or adhesive tape, you can even save electricity 10% or more when the outdoor temperature is 35 degrees!

Air conditioning:

First, close the doors and windows when using the air conditioner, and don't turn the thermostat of the air conditioner to the coldest. Check the outdoor canopy. If it is redundant, please delete it. If the supply voltage is lower than 190 volts, then your air conditioner will only use electricity instead of cooling. When installing air conditioning, try to choose a shady room or a shady side of the room to avoid direct sunlight.

Second, experts remind you to turn off the air conditioner when you leave the room for a long time. When the air conditioner is on, it consumes a lot of power, so avoid frequent switching. The air filter should be cleaned at least once a year.

Water heater:

First, choose an electric water heater with good insulation effect and anti-scaling device. In the area where the time-of-use electricity price is implemented, it can be turned on at the low valley, stored heat and kept warm, and turned off at the peak, which can reduce the electricity bill. Shower temperature is generally set at 50~60℃, and it should be turned off in time when water is not used to avoid repeated boiling.

Second, hot water is needed every day at home, and the heat preservation effect of the water heater is better, so the water heater should always be electrified and set in the heat preservation state.

[Edit this paragraph] Seven energy-saving methods are the most effective.

1. Use thermal insulation materials. 36% of the world's energy consumption is on the heating and cooling of houses. The "zero-energy residential" model houses built in Switzerland and Germany show that it is difficult to estimate the energy-saving potential of heating and cooling with new materials and methods.

2. Replace the light bulb. 20% of the world's electricity is consumed in lighting, of which 40% is consumed by old incandescent bulbs. Under the same luminous quantity, the energy-saving fluorescent lamp not only saves electricity by 75% to 80% compared with incandescent lamp, but also has a service life of 10 times longer than incandescent lamp.

3. Improve the household heat exchanger. The energy efficiency of water heaters, heaters and air conditioners is actually very poor. Only a part of the energy consumed by these heat exchangers is really used to adjust the temperature. Heat pump will change this situation. Heat pump can use the heat energy or geothermal energy in the outdoor air to heat or cool buildings, with little consumption of traditional energy.

4. Transform energy-consuming equipment in the plant. About13 of the world's energy is consumed by industrial departments, which has great energy-saving potential. For example, Japan's Mitsubishi Heavy Industries began to use the waste heat of steelmaking furnaces to generate electricity in the 1980s, saving more than 70% energy.

5. Drive an environmentally friendly and energy-saving car. 65438+ 0.4 of the world's energy is used for transportation, including 2/3 of the oil produced every year. Some energy-saving measures in the transportation field cost nothing at all. For example, keeping tires properly inflated can improve energy efficiency by 6%. In addition, under the same gasoline consumption, the mileage of environmentally-friendly cars such as hybrid cars can be 20% more than that of traditional cars.

6. Improve the energy-saving effect of the refrigerator. More than half of residential electricity consumption is used for household appliances, and 1/5 of global carbon dioxide emissions is caused by residential electricity consumption. Since 1980s, manufacturers have improved the energy efficiency of white goods such as refrigerators by about 70%, but there is still room for improvement.

7. Strive to solve the investment cost of energy conservation. The energy service company can pay the equipment renovation cost needed for energy saving, and then deduct it from the cost saved by customers. For example, some energy companies in California, USA, have successfully reduced the peak demand for electricity by offering extra discounts to energy-saving consumers, which is expected to save a lot of costs for expanding power plants.

(1) Adjust the thermostat knob of the refrigerator. In summer, the indoor temperature changes greatly day and night, so it can be adjusted to "1" before going to bed, and then turned back to "4" during the day. At the same time, the refrigerator should be placed in a cool and ventilated place to ensure the heat dissipation of the radiator.

(2) Increase the air conditioning temperature by 65438 0℃. Generally, it is advisable to set the temperature at 28℃. For example, if the temperature of air conditioner is increased by 1℃, it can save about 0.5 degrees of electricity when running for 10 hour, and the sleep function of air conditioner can save 20% of electricity.

(3) Make full use of the waste heat of the rice cooker. When cooking, the pot is boiling, and the power supply will be cut off as soon as the key is lifted. Using the waste heat of the electric heating plate, press the button after a few minutes, and the rice cooker will automatically cut off power after cooking.

(4) The use of electric water heaters should try to avoid the peak hours of electricity consumption. In summer, you can turn down the thermostat and replace the bathtub with a shower, which can reduce the cost by two-thirds.

(5) Use more energy-saving lamps. If incandescent lamps are replaced by energy-saving lamps, the electricity consumption can be reduced to one-fifth of the original under the same brightness.

(6) Household appliances should not be in standby state. For example, household appliances are in standby state, and power consumption hurts the machine; The brightness of the TV can be lowered appropriately, which can save electricity and make the eyes less tired.

(7) The school classroom can use the human body induction switch to control the classroom lighting, which can control the waste caused by students leaving the classroom without turning off the lights.
