Laney Seagle 2nd Period
What is it?
Renewable energy that is contained in flowing water
How's it done?
Step 1.A hydroelectric power plant uses the force of falling water from a reservoir to turn a turbine that drives a generator.
Step 2. An exciter powers the rotator.
Step 3. As the rotator and its magnetic field turn, an electric charge is created in the stator.
Step 4. A transformer increases the voltage of the current coming from the starter.
Pros of Hydroelectric power
1. Hydroelectric power is clean
2. Hydropower plants have a long life and low operating cost.
3. It's a domestic and renewable source of energy
4. In hydropower plants the source of energy is not destroyed unlike fossil fuel electricity
Cons of Hydroelectric Power
1. Hydropower plants have high set up cost
2. Long construction period and flooding
3. They can also affect fish and wildlife habitats
Where's it used?
1. Turukhansk-USSR 2. Itaipu-Brazil/Paraguay 3. Grand Coulee-USA 4. Grui (Raul Leoni)-Venezuela 5. Tucurui (Raul G. Lhano)-Brazil 6. Sayano-Shushensk-USSR 7. Corpus Posadas-Argentina/Paraguay 8. Krasnoyarsk-USSR 9. La Grand 2-Canada 10. Churchill Falls-Canada
Compared to Fossil Fuels
Fossil Fuel stations are causing global warming
Dams are cheap to operate
Could kill fish and other aquatic life
Can damage coral and other sea life
Humans have been harnessing water to perform work for thousands of years.
The Greeks used water wheels for grinding wheat into flour more than 2,000 years ago
For more than a century, the technology for using falling water to create hydroelectricity has existed
The evolution of the modern hydropower turbine began in the mid-1700s
In 1880, a brush arc light dynamo driven by a water turbine was used to provide theatre and storefront lighting in Grand Rapids, Michigan
Yes or No?
Yes, it is a renewable energy source that isn't as harmful as fossil fuels are. We can get clean energy from hydroelectric power. We need to be using more renewable energy sources.
