A Review: Evolution of Technology towards Green IT

Today, technology is taking its place in every single field; whether it is to ease the life of humans or to save the human life, technology is all around. Due to this tremendous growth, the users of computers and other related resources (like data centers, hardware resources like sensors, printers, storage devices etc.) have increased exponentially. This has resulted in huge manufacturing, usage and wastage which is eventually contributing to low energy-efficiency, more power consumption, excess carbon footprints thus leading to global warming, pollution, and other environmental issues. Keeping in mind the environmental concerns, it has become a need to impose some strict measures to minimize the cause. Optimal utilization of these resources is the only root step towards IT sustainability. This eventually led to the concept of green computing. This paper shows the journey of eco-friendly technology from its origin to its future.
