By damonlappingHydropower is power derived from falling water or fast flowing water, and it's the greatest source of renewable energy in the US. Hydropower accounted for 6.5% of all electricity generation in the US in 2016 and 44% of total utility renewable energy generation in the same year. Hydropower is very much dependent on the water cycle, and the more water available, the more energy that can be produced.
However, in periods of drought, hydroelectric output is negatively affected. But hydropower also has the highest efficiency out of all the energy sources, sitting at 90% efficiency from water flow to the wire. Hydropower is not a new technology, but in recent years with the push towards renewables, the demand for this technology is increasing. This is especially true for India, China and Brazil, whic are all investing heavily in renewable energy. China itself has eight utility-sized hydropower projects in the planning phase.
Here, we look at the Top 10 large scale Hydropower companies from around the world.
