What is Tidal Energy?
The water level nearby the seacoast alters two times a day. This water movement together with the seashore is actually known as tides. A high tide takes place on every new moon and full moon day. Throughout the tide, the level of the water will rise for few meters. The energy being possessed by falling and rising water is actually known as the tidal energy.
With a dam, you could construct them across the narrow opening of the sea. Because of the tide, the water would move in and out all through the openings and flow over the turbines being fixed within the walls of the dam. The movement of the turbines actually generates the electricity.
Tides aren’t really uniform and the rise and fall of the water isn’t large enough for producing electricity into a big scale. Moreover, there could also be few places wherein people find a narrow opening for the dam. Wind energy is actually an indirect form of the solar energy. The wind possesses incredible kinetic energy causing waves into the ocean. The height of these waves is really cool whenever the velocity of the wind is high. It could be used for producing electricity by simply rotating the turbines using their energy.
The biggest limitation of such method is that the location of the turbine and other equipment is by the sea. It needs much of maintenance as well as replacement, making it more expensive.
