Energy Saving in Computers

Save Energy! This is now the motto of most of us as the charge of electricity increased by many energy suppliers and hence the electricity bills are rising. In my previous resource I have shared with you about the saving energy by using “Standby Mode" for our household electronics and appliances. Today I will share with you about saving energy from use of Computers and Printers. Many of us use Computers and Printers at home or at our offices or even in or schools or colleges.

Computers and Printers are the prime assets at all commercial establishments, offices as well as homes. The total energy requirement of computers, servers and printers in our country is more than in Mega Watts. It is also noticed that most of the computer users are unaware of the energy consumption of computers and also how to effectively reduce the same. Get wise about the electricity consumption of computers and tips to reduce the same.

Simple energy Conservation Tips for Computers:

1. Turn off the office computers as well as any photocopiers and printers at night and over weekends.
2. Turn on the computer, monitor, and printer only when you need.
3. Turning a computer on and off doesn't use any extra electricity and won't damage your computer.
4. Shutting it down when not required for some time (recommended 30 mins or more) reduces the wear on your computer increasing its life and cuts down on your power use.
5. Save power by turning off the computer monitor when you'll be away from it for more than 15 minutes.
6. Screen savers are NOT energy savers. Automatic switching to sleep mode or manually turning monitors off is always a better energy-saving strategy.
7. While purchasing, select a printer with power management capabilities. Printers with automatic "power down" features can reduce electricity use by over 65% whilst idle.

Please follow the steps below (for a Windows® based PC) to turn on ‘Power Management Feature' which can save upto 70% of energy.

1. Press ‘Start'
2. Go to ‘Control Panel'
3. Select ‘Power Options' or ‘Power Management Options'
4. Set Monitor turn off time (15 mins recommended) System stand-by time (20/30 mins recommended) and other setting depending on your system.

If you are buying a Computer then go for Laptop because laptops use upto 90% less energy than desktop computers. If you are buying a Desktop then go for flat panel liquid crystal display (LCD) monitors versus conventional CRT monitors. LCD monitors provide up to 70% power savings and provide up to twice the lifespan of CRT monitors. Select the right size of the monitor as larger the size of monitor more the electricity it consumes. A typical desktop computer with a 17-inch LCD monitor requires about 100 watts—65 watts for the computer and 35 watts for the monitor.

So friends if you are unaware of the Power Management feature then immediately set it as per above instruction and remove any screen saver if any you are using. Any suggestions please feel free to post as a response to this below.
