Hydropower involves a valuable transformation for society: moving water is used to generate electricity. The power of water has been used since ancient times: the first mention of a water mill was in Greece, 3rd century BC, in the writings of Philo of Byzantium<\/a>.<\/p>\n

At that time, running water was used to turn wheat into flour. Over time, mankind learned to use it to produce electricity. Using the power of water means no carbon dioxide is emitted into the atmosphere, and the energy source is regenerated by the natural water cycle.<\/p>\n

Thanks to its rich hydrological resources, Romania has already developed a strong network of hydropower systems<\/a>, a good part of national consumption being covered by this clean energy with almost zero emissions. A source of pride for our parents' and grandparents' generation, the \"hydropower stockpile\" can become even richer today, with new investment, benefiting the economy and the environment.<\/p>\n

How it works hydropower<\/a>?<\/h3>\n

Basically, hydropower plants have a reservoir of water, a valve to control the amount of water flowing from the reservoir and a space where the water ends up after the fall. The water gains potential energy before spilling out of the dam. This energy is converted into kinetic energy, which is converted into mechanical energy in the fall by turbines, and then converted into electrical energy by a generator.<\/p>\n

Hydro statistics worldwide<\/h3>\n

The biggest dam: China<\/h4>\n

The Three Gorges Dam in China, with an installed capacity of 22.5 GW, is located on the Yangtze River and cost the equivalent of 32 billion dollars to build.<\/p>\n
