Water energy can be obtained in one of these ways:
- With the help of sea waves energy (or the energy of tides).
- At hydro-electric power plants ( HPPs) and hydro-electric power stations (HPP);
- With the help of river energy ( River bed HPP);
Sometimes several methods can be used at power plants at the same time, and this is normal - dams and stations are usually built in places where water has a naturally strong force.
The energy of sea waves is still being explored. Since the waves can be quite powerful, it is not so easy to construct a relevant plant to harness them.
The working principle is quite similar to one used for generating energy from tides; so let's briefly examine some features of this type. So how does the energy of tides work?
During the tide, water fills special tanks near the shore. These tanks are also called dams. At low tide, the water moves backwards. It is this reverse flow of water that moves the turbine and generates energy.
For this process, it is important that the height difference between tides be as high as possible, at least 10 meters.
