How does hydropower affect society?

Because hydropower plants can generate power to the grid immediately, they provide essential back-up power during major electricity outages or disruptions. In addition to a sustainable fuel source, hydropower efforts produce a number of benefits, such as flood control, irrigation, and water supply.

What countries currently use hydropower?

Hydropower is the most important and widely-used renewable source of energy. Hydropower represents about 17% (International Energy Agency) of total electricity production. China is the largest producer of hydroelectricity, followed by Canada, Brazil, and the United States (Source: Energy Information Administration).

Why hydropower is not clean energy?

Some hydropower reservoirs are actually carbon sinks, taking in more carbon through photosynthesis by organisms living in the water than they emit through decomposition, while others have carbon footprints equal to or greater than, fossil fuels.
