How much electricity does the computer consume every day?

The application of computer in China is more and more common, after the reform and opening-up, the number of Chinese computer users has been rising, the application level has been improved, especially in the fields of Internet, communication, multimedia and so on, has achieved good results.

Ordinary use of computers are more casual, many details of the place did not pay attention to. Now, let's look at the disadvantages of the continuous power supply when the computer shuts down.

How much electricity does your computer consume every day? Do you know that? Many people have thought about it, but have not counted it. Generally, the power consumption of the television is below 80W, the computer is approximately between 250--400w. The power consumption of a computer per month: If it is 300Wx per hour for 10 hours x One months 30 days =90kw, that is, 90 degrees of electricity, this is only a conservative estimate. (Monitor power consumption: 15 inches, 17 inches, 19-inch display power consumption in 60W, 80W, 100W or so).

Last year a report from a university in Canada pointed out that the latest computer, if it has power-saving function, consumes about 35W per hour, is about a little higher than a general brightness bulb, although this waste has little impact on individuals, but if all the computers in the world are on standby for a long time, the amount of electricity wasted per hour is staggering.

The computer also has energy consumption in the sleep state, about 7.5W, it's hard to understand that when you go to standby under Windows XP, power consumption is up to 51.48w!. The motherboard at this time to protect the data, but also in the consumption of electricity; even if the machine is turned off, as long as the plug has not been pulled, the computer still has energy, about 4.81w! such as remote control and intelligent switch to make the appliance more comfortable, but also to the electrical added an additional energy-standby energy consumption.

Often see a number of homes or units of the display with a visual protection screen, originally to reduce the display on the human body of electromagnetic radiation, in fact, this is a misunderstanding. The test proves that the Pao has little effect on the protection of electromagnetic radiation, on the contrary, the installation will result in lower brightness of the image, in order to get the ideal image, the user will be the brightness of the display, increased the load of the display, resulting in electromagnetic radiation does not reduce the rise, and virtually increased the power consumption, it is not worth the candle. Therefore, for the monitor has been certified through the TCO series can be safely used, there is no need to install visual Pao.

Here are some energy-saving suggestions and measures

1, suspend the use of computers, if the expected pause time is less than 1 hours, it is recommended to put the computer on standby, if the pause time is greater than 1 hours, it is best to shut down completely.

2, usually after the computer to normal shutdown, should unplug the power plug or power off the switch on the wiring board, and gradually develop the habit of complete power off, and do not let it in the power state.

3, the use of peripherals such as printers, speakers and so on in time to turn off. (Speaker is a large power consumption)

4, such as optical drive, floppy disk, network card, sound card, such as temporary use of equipment can be in the BIOS screen out. (Power consumption will not fall too much, long time to extend the service life of the equipment)

5, the use of CPU cooling software.

6, reduce the brightness of the display. In doing text editing, the background darkened some, energy-saving while also protecting eyesight, reduce the fatigue strength of the eyes. When the computer plays music, storytelling, novels and other single audio files, you can completely turn off the monitor.

7, many DIY enthusiasts are keen on overclocking. As a technical test is not necessary, if not overclocking as can fully meet the performance needs, or as little overclocking, energy-saving and stable and safe.

In standby state, the device does not cut off the power, and does not run the main function, looks like a shutdown, in fact, there are a few parts of the electrical wiring and components in the live work, this state of electricity consumption is standby energy.

First, it is a question of ideas.

It can be said that all people see because the faucet is not shut off the tap water, 4399 small game is a waste of resources, waste money.

All the people who see no need for illumination are driving the lights during the day, thinking it is a waste of resources and money. And because the computer shut down when the power consumption is unknown, because this is not visible. Can only be measured with instruments. Often the vast majority of computer owners think: Since the computer shut down, how can it still power consumption? After the computer shutdown is not the power consumption? Others think that the computer in the state of power consumption is only a little bit, no fuss. This is precisely the misunderstanding of people's cognition.

Secondly, people's attention is not enough. The reason is caused by incorrect ideas.

As everyone knows, the computer in the state of shutdown, is an electric mouse, in the constant stealing electricity. Standby loss is usually referred to as our most common situation----shutdown after the power supply to connect the motherboard, monitors, printers, ADSL network terminals, routers, etc., at this time +5VSB also to continue for the motherboard, keyboard, mouse and other equipment continues to power, at this time its standby power consumption will also be around 5W. Click the system shutdown, computer host, monitor and its computer peripherals (printers, scanners, ADSL network terminals, routers, etc.) are still in power consumption.

Computer Standby Power Test: (with multimeter model for Mastech?) MS8215)

Condition: When the computer does not boot

Test equipment for computer mainframe, 17″ flat-screen display

Result: The power instantaneous consumes 176 watts

2 seconds to continue standby power consumption of 13.7 watts

Today, the computer has become an indispensable helper of modern office, but also a standing learning and entertainment tools, however, many people do not know that the misuse of computers will cause greater energy waste.

Assuming that institutions, units per computer work 6 hours a day, standby 2 hours, shutdown 16 hours, according to the current number of computers in China 52.99 million units to calculate, the annual shutdown state power consumption can save 620 million degrees of electricity.

Third, most operators pay attention to the Internet environment and service level, often ignoring the cost of electricity consumption. Electricity consumption can be said to be one of the main costs. How to reduce electricity consumption and improve the profit of operators? Of course, the less power consumption the better.

Four. The computer in the shutdown state, there is no real harm to disconnect the power:

1. According to the authoritative Department statistics:

Computer host home Electronics minimum energy consumption top

The use of computer energy-saving devices nationwide electricity saving 500 million degrees per year

China's current computer ownership of nearly 53 million units

Energy expenditure for government departments is \$80 billion a year

2. Computer standby State In addition to power consumption, resulting in unnecessary energy waste;

Long-time electricity will make the electrical appliances in a state of fever, thereby shortening the life of electrical appliances;

In the event of natural disasters, such as: Thunder Thunder will be along the wire (or cable) to hit the electrical appliances.

The computer that is being used by the guest, its power consumption is normal. So the idle computer is also the power consumption is normal, the answer is certainly negative.

The author investigates a lot of computer owners, and their point is that it's just a little bit of power consumption. The majority of these computer owners operate on more than 300 units. This is enough to show that they are a blind spot in this area. It can also be said that they do not have this energy-saving concept of operating costs.

The Internet café operators surveyed reached a maximum attendance of 80%, full time only 1~2 times. The author of My Computer (only host and monitor two) to test, the result is: the computer when the power consumption of the shutdown is 13.7 watts. This is just a computer in the home use, you can imagine if the 300 computers in the absence of customers in the case of the power consumption will be? 300*13=3900 Watts, which means 3.9 kwh of electricity in one hour. Electricity tariffs: 3.4125 yuan. For the attendance is not too high Internet cafes, I am afraid that the night after 10 o'clock to the next day 10 o'clock in the morning period of time the number of guests blank more opportunities. The shutdown power consumption is: 300*13*12=46800 Watts is: 46.8 kw, according to the conventional algorithm: 1-kilowatt one-hour electricity consumption. The power consumption of the day: 46.8 degrees, about the cost of electricity: 46.8*0.875 yuan/-=40.95 yuan per month to pay more electricity: 40.95*30=1228.5 yuan. Pay more electricity per year: 1228.5*12= 14742.00 yuan

No, I don't know. Attendance is dynamic and may actually be calculated at a higher or lower point than the above value. The algorithm above is conventional.
