Hydropower is a form of renewable energy that harnesses the kinetic and potential energy of water to produce electricity. This energy is generated by the fall of water from a height or its circulation in a hydropower plant.
Hydropower is usually a clean and low-impact energy source, but some interventions can be extremely invasive, especially when large artificial dams are created. The problem with artificial dams is that these structures can interfere with the river ecosystem and have a negative impact on the life of animals and plants, including the migration of fish and the destruction of habitats. In addition, the construction of dams can also cause the flooding of inhabited areas and the relocation of local communities. In some cases, the presence of a dam can also compromise the quality of water and the availability of water resources for the population and agriculture.
