Hydro electric energy uses falling water to produce energy.
Currently, Hydropower accounts for around 19% of the worlds energy production.
Hydroelectric stations require constant water supply and are often in high-altitude areas.
A lot Dams are hydroelectric dams. So when they release water it drops and turns the turbines efficiently.
Hydroelectric power in Australia, meets roughly 4.5 % of our needs.
The two many hydroelectric power plants are in Tasmania and the snow mountains (NSW).
