GREEN COMPUTING

Green computing has emerged as a critical discipline in response to the growing environmental impact of modern digital technologies. The rapid expansion of data centres, cloud computing, artificial intelligence, high-speed communication networks, and electronic devices has significantly increased energy consumption, carbon emissions, electronic waste, and resource utilization. This book provides a comprehensive exploration of sustainable computing principles, technologies, and practices aimed at minimizing the ecological footprint of information and communication technologies. It examines the fundamental concepts of energy-efficient computing, thermodynamic limits of computation, green hardware design, sustainable data centre management, energy-aware networking, and environmentally responsible software engineering. Special emphasis is placed on the energy challenges associated with artificial intelligence, cloud computing, and emerging digital infrastructures. The book further discusses measurement frameworks, sustainability metrics, policy initiatives, circular economy practices, and future technologies that support the transition toward net-zero computing. With a particular focus on the Indian context, this work serves as a valuable resource for students, researchers, engineers, policymakers, and industry professionals seeking to understand and implement sustainable computing solutions for a greener digital future.
