    en.wikipedia.org/wiki/Water_power_engine

    The advantages of using hydro power and controlling water flow also has irrigation benefits. In areas that have less rainfall, such as Arizona and Nevada, the ability to control the waterpower engine's water consumption saves water during dry seasons making the region less reliant on natural rainfall.

  3. Hydropower - Wikipedia

    en.wikipedia.org/wiki/Hydropower

    Hydropower (from Ancient Greek ὑδρο-, "water"), also known as water power or water energy, is the use of falling or fast-running water to produce electricity or to power machines. This is achieved by converting the gravitational potential or kinetic energy of a water source to produce power. [1] Hydropower is a method of sustainable energy ...

    The amount of hydroelectric power generated is strongly affected by changes in precipitation and surface runoff. [4] Hydroelectric stations exist in at least 34 US states. The largest concentration of hydroelectric generation in the US is in the Columbia River basin, which in 2012 was the source of 44% of the nation's hydroelectricity. [5]

    Water is required for all life, but since ancient times, mankind has also employed this natural resource for other specifically human productive uses. Millennia ago man learned to navigate on water, learned to dam and divert it for irrigation and build aqueducts and canals to carry it where possible, and learned to convert the power of moving water to mechanical energy to perform work.
