Green computing, also called green technology, is the environmentally responsible use of computers and related resources. Such practices include the implementation of energy-efficient central processing units (CPUs), servers and peripherals as well as reduced resource consumption and proper disposal of electronic waste (e-waste).

Green computing aims to attain economic viability and improve the way computing devices are used. Green IT practices include the development of 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 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: Repurposing existing equipment 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


Ways to go Green Computing!

  • Use the hibernate or sleep mode when away from a computer for extended periods
  • Buy energy-efficient notebook computers, instead of desktop computers
  • Activate the power management features for controlling energy consumption
  • Make proper arrangements for safe electronic waste disposal
  • Turn off computers at the end of each day
  • Refill printer cartridges, rather than buying new ones
  • Instead of purchasing a new computer, try refurbishing an existing device
