What is Green Computing?

Green Computing

Green Computing, also known as green technology or sustainable computing, refers to environmentally sustainable computing or IT. The practice involves the design, manufacturing, use, and disposal of computers, servers, and associated subsystems—such as monitors, printers, storage devices, and networking and communications systems—efficiently and effectively with minimal or no impact on the environment.

The main objectives of Green Computing are to reduce the use of hazardous materials, maximize energy efficiency during the product's lifetime, and promote the recyclability or biodegradability of defunct products and factory waste. Modern Green Computing practices include the development of energy-efficient CPUs, servers, peripherals, and computing systems; the reduction of resource consumption by encouraging shared services (such as cloud computing and virtualization); and the design of algorithms and systems for efficient resource utilization.

Green Computing extends beyond the hardware to include efficient hardware solutions that require less energy to operate. It also encompasses a broader set of corporate policies for environmental sustainability, such as reducing paper usage and adopting environmentally-friendly disposal practices.
