Hydraulic Energy in The World
Hydraulic energy is considered one of the most important renewable energy sources worldwide. Annual precipitation is approximately 119 thousand km³, 60% of which evaporates and 40% reaches lakes and seas through streams. In total, approximately 19% (9 thousand km³) of 47 thousand km³ of water is economically and technically usable.

However, only a small portion of hydropower is used effectively worldwide. Most of the unused potential is in Latin America, Asia and Africa. Especially in developing countries, it is aimed to evaluate this potential more efficiently by installing new hydroelectric power plants.
