What is tidal energy and where can it be found?
The friction of the bulging oceans acting on the spinning earth results in a very gradual slowing down of the earth’s rotation but this is not expected to impact us for billions of years. Therefore, for practical purposes, tidal energy can be considered a sustainable and renewable source of energy. It can prove to be a valuable source of renewable energy to an electrical system. The demand of electricity from a grid varies with the time of the day. Tidal power, although variable, is reliable and predictable and can make a valuable contribution to an electrical system, which has a variety of sources. Tidal electricity provides a good alternative to conventional methods of generating electricity, which would otherwise be generated by fossil fuel (coal, oil, natural gas) etc, thus reducing emissions of greenhouse and acid gases.
