Hydropower

Melting glaciers are creating a green energy windfall in Iceland—but for how long?

Middle Eastern governments are ramping up their green ambitions ahead of the COP27 climate summit but show few signs of reining in fossil-fuel exports

Cuts to states’ use of Colorado River water are needed to prevent levels in Lake Mead and Lake Powell from dropping below a critical point

Earlier snowmelt can leave less water available to generate power during the height of summer

The Department of Energy wants devices that could be deployed to disaster areas that have lost electricity

The irony reveals the need for a greater mix of renewable energy sources

“Great dams trap and tame the water, hoarding its energy until needed. Grandes diques atrapan y amansan el agua, acaparando su energa hasta que el hombre la necesite.“ This photograph is a part of the online photography exhibit “Form and Landscape,” a collaborative project from William Deverell and Gren Hise.

The Itaipú Dam is a hydroelectric power generation facility on the border between Brazil and Paraguay, on the Parana River. The name means “the sounding stone” in Guarani, an indigenous language in South America and one of the official languages in Paraguay.

Summer is called dam removal season by those who cherish the notion of dams being demolished. The hotter, dryer weather limits a river’s flow and seasonal fish migrations  pause, providing the necessary conditions for demolishing the commonly aging infrastructure once erected to provide irrigation, water storage, hydropower and/or flood control.
