Tips To Use Environmentally Friendly PC

Computers can't escape from everyday life today. Work, seek entertainment, or social activites is dependent with the use of computers. This trend is resulting  in rising energy use and costs for each year.


Welcomes Earth Day will be held on 22 April 2011, the APC by Schneider Electric provides tips on using computers efficiently to save costs, extend life of computer equipment and also helps save the earrh.

• Turn the computer off at night so that the computer is only used for 8 hours- to save energy use up to 810kWh per year and 67 percent usage.
• Connect the computer to a surge protector with a master control outlet, so the system can automatically find out when the computer is not used to and then disconnect power to the computers and equipment.
• Use the LCD monitor because it uses less energy and not make the eyes work harder as in the CRT.
• Buy a computer equepped with Energy Star features. For the record, the laptop also uses less energy than desktops.
• Plan the use of computers so  that all activites can be completed in one time, and switch off when no longer used.
• Consider using a smaller monitor. Size of 14-inch monitor uses 40 percent less energy compared with 17-inch monitor.
• Turn on standby mode / sleep and energy usage settings.
• Forget the screen saver because it does not svae energy unless you are still using older versions of the monochrome monitor.
• See re-draft the documents and emails on screen rather than print it.
• Turn off the monitor when not in use rather than using a screen saver.
• Consinder using ink-jet printer-although more slowly than using laser printers, but inkjet use 80-90 percent less energy.
• Buy products based ink from non-plant or oil - because the product is made from recycled sources, require less use of hazardous materials and reproduce colors more bright and clear.
• Turn off the printer and all other auxiliary devices when not in use.
• Do not let the computers stays on at nigth or on weekends
• Choose a dark color as the background screen, because the bright color display uses more energy.
• Reduce the level of room lighting using a computer at work
• Use a network and share printers whenever possible.
• Print using recycled paper. Use a paper that does not use chlorine with 50 to 100 percent post-consmer waste.
• Print on both sides of the paper
• Communication via email as an alternative to memos and faxes.

Currently, there is a mistake of perception or myth of computer usage is common in everyday use, including one of them is the advice to not turn off the computer.

Actually, the computer designed to withstand 40,000 times the cycle on / off, and when useg in a normal computer then the computer can be aged from five to seven years. So by turning off the computer, we not only reduce energy use, but also to reduce heat stress on the computer.

The second assumption of many circulating saying that by turning off and re-turn on the computer will use more energy than leaving in state of light. In fact, the use of energy used by the CPU to boot up much less than by leaving the computer turns on more than three minutes.

Moreover, assuming that the network connection will be disconnected when the computer is also not true low-power/sleep mode. Latest Computer designed so as not to lose the connection or data even in sleep mode state. The CPU is equipped with technology Wake on LAN (WOL) can be left in sleep mode all night and next day the user has received the data sent
