1) What is the major disadvantage of wind power generation?

Pollution effect is more Requires high technology Plant installation more complicated Wind power is not constant and steady

Correct Answer: Wind power is not constant and steady

2) What is the function of turbine used in tidal power generation?

Prevents water flow to other parts of dam Converts potential energy into kinetic energy Keeps the water flow from low to higher level Converts kinetic energy into potential energy

Correct Answer: Converts potential energy into kinetic energy

3) What is the advantage of non-conventional energy source?

More reliable Low initial cost Efficiency is high Greenhouse effect is avoided

Correct Answer: Greenhouse effect is avoided

4) How the potential energy from water flowing is converted as kinetic energy to generate power?

By storing water in high quantity By using surge tanks at the water canal By using water turbine to drive alternator By creating high head through penstocks

Correct Answer: By creating high head through penstocks
