Net electricity generation from conventional hydro-power peaked in 1997 at 356 billion kWh, then steadily declined through 2001, and has since remained relatively stable. In 2009, hydro-power generation was 272 billion kWh - 24% lower than in 1997.

The Center for Sustainable Systems, within the School of Natural Resources and Environment at the University of Michigan, leads interdisciplinary research to support the design, assessment, and management of systems that meet societal needs in a more sustainable manner.
