1.	Question : What is Tidal energy? What are it's advantages?
Answer» Solution :The energy obtained from the movement of WATER, due to ocean tides is called tidal energy. Tides are the rise and fall of sea LEVEL, caused by the COMBINED effects of the gravitational force. A tidal stream is a fast flowing body of water created by tides. Turbines are placed in tidal STREAMS. When the tides hit the turbine, the turbine rotates and converts the tidal energy into electric energy. Advantages: • It does not produce any pollution. • It does not use any fuel and does not produce any waste. •Tidesarepredictable, so tidal energy can be produced at anytime. • Water is denser than air, and therefore can generate electricity at lower speeds than windturbines.
