Green Computing

Definition - What does Green Computing mean?

Green computing is the environmentally responsible and eco-friendly use of computers and their resources. In a broader way, it is also defined as the study of designing, manufacturing/engineering, using and disposing of computing devices in a way that reduces their environmental impact.

Many IT manufacturers and vendors are continuously investing in designing energy efficient computing devices, reducing the use of dangerous materials, and encouraging the recyclability of digital devices and printing paper. Green computing practices were primarily introduced by the Environmental Protection Agency in 1992 with the launch of the Energy Star program.

Also known as green IT.

Techopedia explains Green Computing

Green computing or green IT aims to attain economic viability and improve the way computing devices are used. Green IT practices include working towards environmentally sustainable production practices, energy efficient computers and improved disposal and recycling procedures.

To promote green computing concepts at all possible levels, the following four complementary approaches are employed:

  • Green Use: Minimizing the electricity consumption of computers and their peripheral devices and using them in an eco-friendly manner.
  • Green Disposal: Making over an existing computer or appropriately disposing of or recycling unwanted electronic equipment.
  • Green Design: Designing energy-efficient computers, servers, printers, projectors and other digital devices.
  • Green Manufacturing: Minimizing waste during the manufacturing of computers and other subsystems to reduce the environmental impact of these activities.

Government regulatory authorities are also actively working to promote green computing concepts by introducing several voluntary programs and regulations for their enforcement.

There are some general tactics computer users can employ to make their use greener:

  • Use the hibernate mode or sleep mode when away from the computer for an extended period
  • Use flat-screen or LCD monitors instead of conventional cathode ray tube monitors
  • Buy energy efficient notebook computers instead of desktop computers
  • Activate the power management features for controlling energy consumption
  • Make proper arrangements for disposing of electronic waste in a safe manner
  • Turn off computers at the end of each day
  • Refill printer cartridges rather than buying new ones
  • Instead of purchasing a new computer, try to refurbish an existing device
