Advanteges of Hydro Power Stations
- No fuel charges
- Less supervising staff is required
- It is very cheap and easily used
- The station is lasting and strong and doesn't collapse easily
-it takes few minutes to run & synchronize
- No fuel transportation is needed
-No ash, flue gas problem and does not pollute the atmosphere.
This is how Hydro Power
Disadvantages of Hydro Power Stations
- Stations sink many territories
- After building Stations many people have to move to different places
- The harvest of population is decreasing
- Building stations cause climite changes.
- Stations cause catastrophes by bursting out and overwhelming territories.

History of Hydroelectric Power
- Nearly 2000 years ago the Greeks used water wheels to grind wheat into flour
- In the 1700's, hydropower was broadly used for milling of lumber and grain and for pumping irrigation water
- Appleton, Wisconsin became the first operational hydroelectric generating station in the United States, in 1882, producing 12.5 kilowatts (kW) of power
- The total electrical capacity generated was equivalent to 250 lights
- Within the next 20 years roughly 300 hydroelectric plants were operational around the world
- 40% of the United States' electricity was provided by hydroelectric power in the early 1900's
How do hydro power stations work?
Modern approaches to hydropower usually involve the damming of a river to increase water pressure. The water is then let out through a small tube that leads to the water wheel, generally a fairly small, compact device that forces the water to push it out of the way if it wants to continue its downward motion. Because of the high pressure and steep angle, hydropower plants can spin their water wheel, which in turn spins the generator at incredible speeds.
