With drastically increasing demands for cloud computing and big data processing, the electric energy consumption of data centers in the U.S. is expected to reach 73 billion kWh by 2020 [1], which will account for approximately 10% of the U.S total electric energy consumption. A large portion of this consumption is caused by losses from inefficient power delivery architectures that require a lot of attention for improvements [2], [3].
