N5 – CS – Environmental Impact

Describe the energy use of computer systems, the implications on the environment

  • It is estimated that two billion computer systems are in use in the world – these all use energy. As user we need to consider how to reduce unnecessary energy use.

 

and how these could be reduced through:

  • Settings on monitors – reduce brightness, activate efficiency mode, use energy efficient monitors.
  • Power down settings – power-down after a period of inactivity, control setting for single components.
  • Leaving computers on standby – power consumption is reduced but it still uses some power, machines should be shut down when not in use.
