Green Computing

Case study: Green Computing

Green computing is responsible and eco-friendly use of computers and their resources. Its also defined as the study of designing, manufacturing/engineering. It uses and disposes of computing devices in a way that reduces their environmental impact.

Steps you can take to contribute to green computing
1) Power down when not in use

Computer displays use a large amount of energy. So we need to shut down the computer when not in use. Also, remember that a screensaver doesn’t save power. We can also use sleep mode if we don’t want to shut down. That will save energy and also restore the system to its current state when you need it again.

2) Make use of power-saving features

The computers include power saving options. Using various features we can perform power saving tasks. The tasks are like:

  • shutting off unused hard disks
  • powering off a monitor after a certain time placing the computer into sleep mode after a set period inactivity.
  • These techniques are especially useful on laptops to help retain the battery life.
3) Buy energy-efficient hardware

We need to look out for energy-efficient components when buying a new computer. The items such as green hard drives and low-energy processors. While performance is slower they can use significantly less power. Buying an energy-efficient power supply unit for a PC can help the environment and save money. This factor contributes to green computing.

4) Use a laptop

Laptops are better for the environment than desktop computers. This is because as they have components that need less power.

5) Recycle responsibly

Computer hardware is packed with all kinds of material which can be hazardous to the environment. So we need to make sure you dispose of old components in a proper manner. Don’t throw broken technology in the bin, take the time to track down local recycling schemes. One can also be able to sell some things to make a little extra cash. We can check with the authorities for the safe disposal of the hardware. This factor contributes to green computing.

6) Go digital

Advances in technology mean our reliance on physical items has been reduced by a lot. You don’t need to buy a CD when music can be purchased from Amazon, iTunes, or many other sources. Now rather than printing documents and photos make use of email and instant messaging to send the documents.

7) Don’t buy new, upgrade and maintain

Most laptops can be upgraded. So instead of buying a new laptop once the previous one lows down. We should upgrade our laptops. It can be upgraded by :

  • clearing out old files
  • reinstalling the operating system.
  • It can improve performance without costing any money with these methods.
Advantages :
  • Less energy usage and costs
  • Less cooling requirements and costs
  • Slightly cooler computers which improve the lifespan
Disadvantages :
  • Rapid technology change
  • Some computers that are green may be considerably under-powered
  • It is actually quite costly
