Cloud computing (CC) is a promising area in distributed computing. This technology can achieve communication, storage, processing, high performance, hosting and services on demand to cloud costumer. Energy consumption cost and environmental effect are dynamic challenge to cloud computing. Data centers are the backbone of cloud computing. They continue to be challenging problems to energy efficiency. The authors investigated previous research based on energy efficiency approach and obtained the conditions to facilitate green cloud computing.
