READ MOREHydro energy. As a renewable energy resource, hydro power is one of the most commercially developed. By building a dam or barrier, a large reservoir can be used to create a controlled flow of water that will drive a turbine, generating electricity. This energy is: Reliable. Easy to store. Cheaper to setup than other renewable sources.
READ MOREIt produces the highest share of all types of renewable energy; approximately 71% of the total green energy. Hydroelectric energy may not be as handy as solar energy, but construction crews can get necessary power from nearby hydropower plants rather than relying on generators.

READ MOREThis comparison is misguided: the uncertainties around these values mean they are likely to overlap. The key insight is that they are all much, much safer than fossil fuels. Nuclear energy, for example, results in 99.9% fewer deaths than brown coal; 99.8% fewer than coal; 99.7% fewer than oil; and 97.6% fewer than gas.

READ MOREHydropower refers to the use of water''s movement as a medium for energy generation. Including dams, tidal and wave-power, hydroelectricity''s wide range of sources reflect its versatility and ability to be used almost everywhere. A dominant form of sustainable power, hydropower was responsible for 4,200 TWh of energy production in 2018.
