Hydro Energy



Hydroelectricity is the term referring to electricity generated by hydropower; the generation of electrical power through the utilization of the gravitational force of falling or flowing water.

In 2015 hydropower created 16.6% of the worlds entire electricity and 70% of all renewable electricity, and is expected to increase about 3.1% each year for the next 25 years.

Hydropower is created in 150 nations, with the Asia-Pacific region creating 33 percent of worldwide hydropower. China is the largest hydroelectricity producer, with 920 TWh of generation in 2013, representing 16.9 percent of domestic electricity use.

The price of hydroelectricity is comparatively low, making it a competitive source of electricity that is renewable. The hydro station uses up no water, unlike gas or coal plants. The average cost of electricity from a hydro station bigger than 10 megawatts is 3 to 5 U.S. cents per kilowatt-hour.

With a dam and reservoir it’s also a flexible source of electricity since the number produced by the station can be changed up or down very quickly to adapt to changing energy demands. Once a hydroelectric complex is built, no waste that is direct is produced by the project, and has a substantially lower output level of greenhouse gases than fossil fuel powered energy plants.
