Different Types of Alternate Energy Sources

Tidal Energy

• Tidal energy is a form of hydropower that converts energy obtained from tides into useful forms of power, such as electricity.
• Tides are created by the gravitational effect of the moon and the sun on the earth causing cyclical movement of the seas.
• Tides can be harnessed in three different ways; tidal streams, barrages, and lagoons.

Advantages

• Tides are predictable and constant, thanks to gravitational forces. Only needing to assess the low or high tide, makes it easier for engineers to design efficient systems.
• Protects coastal flooding due to the stability of the rock armour under different design conditions. Tidal ....
