Green computing involves the responsible use of computers and related resources to reduce energy consumption and be environmentally aware. Today, computers help make the world a better place by providing information at our finger-tips and allowing instant communication. There are a number of designs and models available in the market but today computers are one of the most resource-heavy and disposed items available. This has a negative impact on the environment as outdated computers that are disposed off end up either in landfills or are pulled apart for their metal content, in the bargain polluting the environment. Green computing ensures that computer resources are efficiently used by controlling power consumption as well as manufacturing computers that are recyclable and use fewer hazardous materials.
