Hydroelectricity is electricity generated by harnessing the power of moving water. The energy is made from gravitational force of falling or flowing water. ... Hydropower is generated in large plants that uses the same idea as mills, only on a much larger scale. The generators that make the energy, are attached to large turbine devices that spin at a very fast speed because the water rushes through the turbines.

Method and apparatus for reducing bird and fish injuries and deaths at wind and water-turbine power-generation sites
A simple system is provided to dramatically reduce the number of bird fatalities and injuries, as these are bird-kills that man should be able to do something about. Essentially, the inventive apparatus comprises one or more instantaneously inflatable mini-airbags on turbine blade leading edges which, in the “stowed position” are tightly conformally elastically wrapped around or juxtaposed to the turbine blade surface(s) and / or edges(s) thereby not affecting the blade's aerodynamic efficiency. The airbag(s) can be activated and restowed or recollapsed very rapidly, thereby not significantly negatively impacting the operational efficiency of the wind machine. In a similar manner, fish-kills or injuries taking place in the turbine impellers of hydroelectric power-generator facilities may be avoided (as opposed to ameliorated) using another inventive system and method taught herein, this one being primarily a collision avoidance system which does not require the problematic alteration of the turbine blades themselves.

A wind-hydro power generation system and its power generation method which use both wind power and hydraulic power. Increasing the size of a hydraulic turbine for the hydraulic power generation may result in the decreased rotation power of the hydraulic turbine caused by the resistance of the wind when blades on the hydraulic turbine come out of the water. The present invention has a blade rotation system on the blades of the hydraulic turbine so that the blades may rotate according to the direction of the wind. As a result, wind resistance is not effected to the rotation of the hydraulic turbine even when the blades on the hydraulic turbine are out of water, but enhances the rotation power of the hydraulic turbine, which enables the use of wind power and hydraulic power at the same time.
