How does hydroelectricity work?
Hydroelectric energy is power generated through the power of flowing water, which spins a turbine connected to an electric generator. Due to water’s predictable nature, hydropower is actually one of the most dependable and reliable sources of renewable energy.
Hydro generators can vary tremendously in size, ranging from as small as 50kw up to a whopping 2,000kw, like the Hoover Dam.
Usually, a hydropower system is constructed via three elements: a power plant from which the electricity is produced, a river or dam that can be opened and closed to control the flow of water, and finally some form of the reservoir in which the water can be stored.
With such a simple yet innovative system in place, you have a great level of control on the flow of energy, which is of course a huge advantage, particularly if you are using it with other renewable energy sources such as wind power or solar panels.
