Hydro energy production constitutes the most extensively exploited renewable energy type all over the world. It is renewable depending on the hydrological cycle with the least greenhouse gas emission into the atmosphere. This chapter presents facades of hydroelectric energy generation and exposes all the alternatives for its production. Basic definitions, production methodologies, calculation methods, case studies, present and future prospects are presented for further possible researches. Pros and cons of the hydro energy production facilities are explained with emphasis that the hydropower generation is the least harmful to the environment provided that basic principles are considered in plant design.
