1. Hydroelectric power
Student Work

2. How is it produced?
Dams- water is released through the reservoir which flows through a turbine, spinning it, which activates a generator to produce electricity. The electricity travels up to towers on top of the dam which is then sent to power stations

3. Where is it produced?
Major U.S. Hydroelectric Dams: Hoover Dam, Niagra Falls, Appleton, Wisconsin
Major producers in the World: China, Canada, Brazil, US, Russia

4. What is it used for? Hydroelectricity provides power for cities.
-Ex: The Three Gorges Dam is the largest electric power plant in the world. It sits on the Yangtze River in Hubei, China. This dam has a total generating capacity of more than 18,000 megawatts, supplying power to millions of houses, schools, and hospitals.

5. What are the pros and cons?
1)Renewable:
While water is a renewable resource,
there are limits to availability of
reservoirs where hydroelectric plants can be built.
2)Non-Pollutant:
Hydroelectric power creates no pollution, but pollutants are an issue during the plant construction process.
3)Reliable:
Hydroelectric power is always reliable with rare occasions of flaws in the process.
4)Flexible:
Water flow can easily be adjusted which adjusts the output of energy.
5)Safe:
Unlike other sources of power, hydroelectricity is not harmful to our health.
CONS:
1)Environmental consequences:
Hydroelectricity causes damming which can harm the environment. It also can harm the fish population in the water.
2) Expense:
Although construction is costly,
hydroelectricity does not require a
lot of labor to run it.
3)Droughts:
Since power relies on our water
source, a drought means no water and also no power.
4)Limited reservoirs:
Only certain waterways are capable of becoming efficient reservoirs for hydroelectricity. Already most of the available waterways are being used as hydroelectric
plants.
