Hydropower: An Essential Partner of Renewable Energy Source

In 2006, the 17 percent of the world’s electricity that was generated from hydropower represented nearly 90 percent of renewable electricity generation worldwide; Hydropower is an important source of renewable energy and produces extremely small quantities of carbon dioxide. Between 1998 and 2008, renewable electricity production in the world rose from 2,794.9 to 3,762.6 TWh, i.e. an additional 967.6 TWh. As a final conclusion, despite hydropower’s high initial costs, its long-term overall costs tend to be low. The average cost of electricity production by hydropower is still very attractive for the moment. In the next future, hydropower will keep his position, in front of the other renewable sources of electricity, on the same level with biomass, better that wind power and much cheaper than solar energy.
