  Nowadays cloud computing adoption as a form of hosted application and
services is widespread due to decreasing costs of hardware, software, and
maintenance. Cloud enables access to a shared pool of virtual resources hosted
in large energy-hungry data centers for diverse information and communication
services with dynamic workloads. The huge energy consumption of cloud data
centers results in high electricity bills as well as emission of a large amount
of carbon dioxide gas. Needless to say, efficient resource management in cloud
environments has become one of the most important priorities of cloud providers
and consequently has increased the interest of researchers to propose novel
energy saving solutions. This chapter presents a scientific and taxonomic
survey of recent energy efficient cloud resource management' solutions in cloud
environments. The main objective of this study is to propose a novel complete
taxonomy for energy-efficient cloud resource management solutions, review
recent research advancements in this area, classify the existing techniques
based on our proposed taxonomy, and open up new research directions. Besides,
it reviews and surveys the literature in the range of 2015 through 2021 in the
subject of energy-efficient cloud resource management techniques and maps them
to its proposed taxonomy, which unveils novel research directions and
facilitates the conduction of future researches.
