1, the choice of monitor to appropriate, because the larger the display, the more energy consumed; 2, a short break, try to enable the computer’s “sleep” mode, more sleep, less standby; 3, shut down the power to unplug. Because as long as the plug is not unplugged, the computer hardware power on the case as usual, there is about 5 watts of power consumption; 4, reject the screensaver. Complex screensaver than normal operation also consumes power, it is better to hibernate and turn off the monitor. TV: set-top box must be unplugged 1, the brightest state of the TV set than the darkest state to consume 50%-60% more power, if the brightness will be lower, generally can save power about 10%; 2, the volume settings to moderate, the volume of the size and power consumption is proportional; 3, the majority of set-top boxes do not have the so-called standby power-saving function, in the standby state of the TV set is still in a high energy consumption state. Don’t forget to turn off the set-top box after shutting down the TV and set-top box power supply are cut off the most power saving. Water heater: summer open to about 45 degrees on it 1, in general, the thermostat to about 65 degrees Celsius most power saving. High summer temperatures, heating speed, can be moderately adjusted down to about 45 degrees, washing is also enough; 2, the shower than the tub to save more water and electricity, can reduce the cost of two-thirds; 3, generally recommended in the bath 1 hour before the start of the electricity heating, after the shower off. Lighting: energy-saving lamps than traditional incandescent lamps to save electricity about 60% 1, energy-saving lamps brightness, low power, such as 11-watt energy-saving lamps brightness can be equivalent to 60-watt incandescent lamps; 2, electronic ballasts, saving 30% of electricity than traditional ballasts; 3, LED and other power-saving lamps than traditional incandescent lamps to save electricity about 60% or more. Microwave oven: heating before using cling film set good food can save electricity 20%-40% 1, heating before using cling film set good, not only to better ensure the original taste of food, but also to shorten the heating time, thus saving electricity; 2, the more regular the shape of food, cut small pieces (5 cm or less is appropriate), the more even heating more energy efficient; 3, the food from the refrigerator is best first put in the room temperature A period of time before heating, more energy efficient. Refrigerator: food do not discharge too tight 1, refrigerator food discharge too tight will affect the air convection in the refrigerator, food cooling difficulties, increase power consumption; 2, hot food is best natural cooling and then into the refrigerator; 3, the refrigerator should often defrost, clean, if the evaporator skin frost thickness up to 10 mm, the heat transfer efficiency will drop more than 30%, the refrigeration effect is a big hit, resulting in the compressor keep running, increase power consumption. Washing machine: control the amount of water temperature can save energy 1, according to the amount of clothes to choose the amount of water. The water volume is too much, which will increase the water pressure of the wave plate, increasing the burden on the motor and increasing electricity consumption; the water volume is too little, which will affect the up and down of the clothes when washing, increasing the washing time and increasing electricity consumption; 2, choose the water temperature according to the temperature. 30 degrees water is better for clothes. High summer temperatures, the tap water itself has a certain temperature, for the settable water temperature washing machine, you can cancel 30 degrees water settings.
