Energy Development There are a large number of energy resources, many of which have important implications for water resources. There is a recent report on USGS activities that may be of interest. It can be found here: https://www.nap.edu/download/25141 ; National Academies of Sciences, Engineering, and Medicine 2018. Future Directions for the U.S. Geological Survey's Energy Resources Program .Washington, DC: The National Academies Press. https://doi.org/10.17226/25141. ; As a starting point for discussion, there is a lengthy article on energy development in Wikipedia, which covers most (but not all) technologies that are now being used or under consideration.
