Quick Facts. 1  Hydropower is a renewable, efficient, and reliable source of energy that does not directly emit greenhouse gases or other air pollutants, and that can be scheduled to produce power as needed, depending on water availability.ydropower, or hydroelectricity, is electricity generated by the force of moving water in the penstock [8] of a hydropower unit. Turbines are used to capture the kinetic energy of water by converting it to electricity as the falling water spins the turbine.
In this article, we will look at how hydroelectric dams work, and what are their advantages and disadvantages. slide 1 of 5. Hydroelectric power produced by hydroelectric dams accounts for 20% of the worldâs total production of electrical energy. typical hydroelectric dam has the following main parts: 1  Water Reservoir: A large quantity of water is stored in a reservoir (or dam). 2  The height or depth of the stored water determines how much electricity can be generated. 3  As the depth increases, the generation of electricity also increases.
