Green computing, also known as sustainable computing, is the practice of designing, manufacturing, using, and disposing of computers and other electronic devices in an environmentally friendly way. This includes reducing energy consumption, minimizing electronic waste, using renewable resources, and promoting recyclability. Green computing aims to reduce the environmental impact of technology and contribute to a more sustainable future. Researchers in this field study ways to improve the efficiency of computer systems, develop environmentally friendly materials for electronics, and promote responsible practices in the IT industry.
