Green computing refers to environmentally sustainable practices in the design, manufacturing, use, and disposal of computers and related technology. It aims to reduce energy consumption, minimize waste, and lower the carbon footprint associated with computing activities. This includes using energy-efficient hardware, optimizing software for lower power usage, and promoting recycling of electronic devices. Another aspect of green computing is the development of cloud computing and virtualization, which allow multiple users to share resources, reducing the need for individual physical machines. Additionally, organizations are encouraged to implement policies that support remote work, further decreasing energy use and emissions from commuting.
