REFERENCES & NOTES
This report provides an independent assessment of the technical literature and the nature of existing estimates and surveys of
electric demand in the global and U.S. ICT ecosystems. This analysis was supported in part by the National Mining Association
and American Coalition for Clean Coal Electricity. DPG is responsible for the contents of this report and the analyses contained
herein. The analysis and the graphics developed during the course of this research represent the independent work and views of
DPG and are intended to contribute to the dialogue on the present and future energy requirements of the ICT ecosystem.
