Abstract: Currently, computers are not only used in offices but utilized at home as well. The amount of energy consumed by the growing daily use of computers contributes to a rise in the atmosphere's carbon content. The IT sector is mostly to blame for 3% of the world's energy usage, which is rising by 20% annually. These days, green computing is a very emerging topic today. He is responsible for the use of computers and associated resources. It encompasses the application of energy efficient processors, servers and peripherals, along with less resource usage and appropriate electronic waste disposal waste. Enhancing the life cycle efficiency of IT devices and approving the recycling of wasteful items and manufacturing waste are the main objectives of green computing. The methods for conserving green energy and their potential applications are discussed in this article. By "aligning all IT processes and practices with the core principles of sustainability, which are to reduce, reuse, and recycle; and finding innovative ways to use IT in business processes to deliver sustainability benefits across the enterprise and beyond," green computing can also create beneficial solutions. Green computing and green chemistry share many of the same objectives, including minimizing the use of hazardous materials, optimizing energy efficiency over the course of a product's lifetime, and fostering the recyclable or biodegradable nature of factory waste and non-operational products .
