Computer hardware consumes a lot of energy, and considering the technological boom of the last twenty years, represents a relatively new strain on the environment. Also, the waste element of computer hardware is a serious environmental problem. Organisations such as Computer Aid International deal with unwanted computer hardware, and legislation such as The WEEE Directive covers computer waste. In terms of energy consumption, most new hardware comes equipped with power-saving devices, in an attempt to cut down on both electricity costs and effects.
Ecological screen-savers, which activate when the PC is left idle, are an example of certain features that can reduce energy consumption, switching off the monitor. Other monitor innovations include the ‘Energy Star’ and similar models. These monitors are specially designed to conserve energy and comply to stringent US Environmental Protection Agency standards.
