Hydroelectric energy is the cleanest form of renewable generation as it does not release any harmful gases, carbon dioxide, and other pollutants which directly or indirectly affect the environment.
1 Hydropower is the most important and widely-used renewable source of energy. 2  Hydropower represents 19% of total electricity production. 3  China is the largest producer of hydroelectricity, followed by Canada, Brazil, and the United States (Source: Energy Information Administration).ypical hydroelectric powerplant. Hydroelectric energy is produced by the force of falling water. The capacity to produce this energy is dependent on both the available flow and the height from which it falls. Building up behind a high dam, water accumulates potential energy.
