According to a recent IEA publication , global data center electricity use in 2020 was 200 – 250 TWh1 , or around 1 % of global final electricity demand . Major builders of data centers are committing to building renewable power generation facilities along with their data centers , lessening the strain on the local utilities while also helping them to meet local , state , and federal requirements for renewable energy production .

This paper explores the short- and long-term ramifications the renewable power source has on the architecture of the power train in the data center .

Historical trends of energy consumption in the US According to the US Energy Information Administration provided graph , the United States has relied on coal , oil , and natural gas to provide most of the energy consumed since the early 1900s . The oil embargo of the 1970s , the formation of the Environmental Protection Agency ( EPA ) during the Nixon administration , and the rampant smog pollution from vehicles and coal-fired power plants spurred America to begin weaning itself off oil and coal as the primary fuels for power generation . Coupled with the needs of a growing population , it was essential to start investing in new sources of energy capable of scaling their outputs to match the ever-increasing lifestyle and GDP of the country and the rest of the world . �
