Green computing

Green computing, also known as green IT, refers to the study and practice of designing, manufacturing, using, and disposing of computers, servers, and associated subsystems—such as monitors, printers, storage devices, and networking and communications systems—efficiently and effectively with minimal impact on the environment.

History

The concept of green computing originated in the early 1990s when the Environmental Protection Agency (EPA) launched the Energy Star program. The Energy Star label became a common sight, especially in notebook computers and displays.

Importance

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.

Practices

Virtualization

Virtualization involves running multiple operating systems on a single physical system and sharing the underlying hardware resources. It can potentially save a significant amount of energy by reducing the need for physical systems.

Power Management

Power management techniques are used to reduce a system's electricity consumption. This can be achieved by implementing power-saving features in the system's hardware and software.

Resource Allocation

Efficient resource allocation can help reduce the number of servers in use, thereby saving energy.

Challenges

Despite its benefits, green computing is not without its challenges. These include the high initial cost of implementing green computing practices and the lack of awareness about the importance of environmentally friendly computing.
