Green computing aims to reduce the environmental impact of computers and associated systems through efficient and effective design, manufacturing, use and disposal with minimal harm to the environment. It began in the 1990s under programs like Energy Star that aimed to reduce e-waste and resource use. Approaches include virtualization, efficient displays and storage, and material recycling. Companies like VIA Technologies are developing carbon-free, solar-powered and energy efficient computing solutions. Adopting green computing brings advantages like reduced energy usage, conservation of resources, and environmental protection while helping save the planet for future generations.
