Hydropower is currently the most common source of renewable energy, accounting for more than 3,400 terawatts, or about 16 percent of global electricity production, in 2010. As hydropower uses a fuel—water from the hydrologic cycle—that is not consumed in the process, it is, in principle, a renewable form of energy. The use of hydropower can make a contribution to saving exhaustible energy sources such as fossil fuels.
