Water is one of the most ancient sources for the production of energy. Today, slightly over 2.2% of primary energy, and approximately 16% of energy consumption worldwide, is obtained from the operation of 800,000 dams of which 45000 are more than 15 meters high. On a global scale, catch basins occupy approximately 300,000 square kilometres, an area that is as large as Italy. For many countries, hydropower is an important source for producing electricity: in Norway covers 95.7% of electricity production, in Brazil, 83.8%, in Venezuela 72.8% and % in Canada 60.3%.
