Question

two similarities and two differences between Hydroelectric power station and gas turbine power station

Answer 1

Answer:

Hydroelectric Reservoirs

A hydroelectric power station consists of turbines that rely on a gravity flow of water from the dam to turn a turbine to generate electricity. The water can be either released to the river downstream of the dam or pumped back into the reservoir and reused. Generally, hydroelectric dams are built specifically for electricity generation and are not used for drinking or irrigation water. Hydropower provides 19% of the world's total electricity supply, and is used in over 150 countries, with 24 of these countries depending on it for 90% of their supply. The countries producing most hydroelectric energy are China, Canada, Brazil, USA, and Russia.

Explanation:

With Hydroelectric power water is artificially stored in a high place, so it can be released and flow to a low place and through a generator. With Tidal energy the movement of water is also used to power a generator, but the flow of water is caused by the changing tides.
