Hydroelectric renewable energy extracts the force from moving water to generate electricity. The concept of hydroelectricity is to make a huge mass of water fall at a very high speed and use rotating turbines to create electricity.

Hydroelectric renewable energy is quite safe and environmental friendly as it does not result in any harmful emissions and gasses that damage the environment. Further, it is a method of power generation that has been long established since ancient times.

Hydroelectric power can be generated on a large scale as well as on a smaller scale. Both establishments use the same underlying principle, with only the turbine sizes varying. Hydroelectric power is most commonly used on a larger scale though. This involves damming a river or any other huge body of water that is flowing at a great speed, and allowing the water to go across the dam in a controlled environment.

Small scale hydroelectric power is not that popular in the context of electricity generation because the effort involved is greater to generate a relatively smaller volume of electricity. This is because unlike in the case of other alternative sources of power, the general public may not have easy access to such large volume of water with free access. Therefore in most scenarios, you will see hydroelectricity being generated at national level with large scale projects.

Another reason why hydroelectricity has to be a large scale national project is because it involves a heavy social impact on the community around the project. There is suddenly a huge mass of water running in the vicinity and most of the time, if the body if water is artificially created, there will be huge displacement for families. When government undertakes such projects they ensure that the affected families and individuals are satisfactorily compensated and well looked after.

Hydroelectricity is wonderful in terms of generating large volumes of power unlike in the case of solar and wind power. There are some countries that produce majority of their electricity supply through hydroelectric renewable energy.
