Floating solar's potential to support sustainable development

A study, published in Nature Energy, is among the first to explore the floating photovoltaics (FPV) at the continental scale, finding that FPV installed at existing major reservoirs could produce 20–100% of the electricity ...

Strengthening the grid's 'backbone' with hydropower

Argonne-led studies investigate how hydropower could help Alaska add more clean energy to its grid, how it generates value as grids add more renewable energy, and how liner technology can improve hydropower efficiency.

Hydropower is global. Should hydropower research be, too?

When Dany Tome first arrived at the National Renewable Energy Laboratory's (NREL's) campus in Golden, Colorado, he did not notice the golden grasses waving from the hillsides or the solar panels set in neat, geometric rows ...

Hydropower

Hydropower, hydraulic power, hydrokinetic power or water power is power that is derived from the force or energy of falling water, which may be harnessed for useful purposes. Since ancient times, hydropower has been used for irrigation and the operation of various mechanical devices, such as watermills, sawmills, textile mills, dock cranes, and domestic lifts. Since the early 20th century, the term is used almost exclusively in conjunction with the modern development of hydro-electric power, the energy of which could be transmitted considerable distance between where it was created to where it was consumed.

Another previous method used to transmit energy had employed a trompe, which produces compressed air from falling water, that could then be piped to power other machinery at a distance from the energy source.

Water's power is manifested in hydrology, by the forces of water on the riverbed and banks of a river. When a river is in flood, it is at its most powerful, and moves the greatest amount of sediment. This higher force results in the removal of sediment and other material from the riverbed and banks of the river, locally causing erosion, transport and, with lower flow, sedimentation downstream.
