The aim of this review paper is to study the energy efficient techniques in cloud computing to achieve green cloud computing. As we know Energy is crucial research in today's world. Due to emerging trends in technology, consumption of energy is growing independently but energy production capabilities are not growing as fast so, efforts to produce more energy is proving hazards for our environment that is usually becoming very important to adapt energy saving. Cloud computing is an evolving technology as compared to other technology.it has changed the ways of computation and storage.but cloud is a energy hungry technology with data centre running hundreds of hosts. 24*7 energy consumption is very high. So, there is the need to study various techniques to reduce this energy consumption of the clouds.
