PRESENTATION OUTLINE
HYDROELECTRIC
- I am doing hydroelectric for this project. Here are some facts.
- It prevents the burning of 22 billion gallons of oil or 120 million tons of coal each year.
- Hydropower does not produce greenhouse gasses or other air pollution.
- World-wide, about 20% of all electricity is generated by hydropower.
- Hydropower provides about 10% of the electricity in the United States. (1)
HOW DOES THIS TECHNOLOGY WORK?
- Water is needed to run a hydroelectric power-generating unit.
- The water is held behind a dam, forming an artificial lake, or reservoir.
- The force of the water being released from the reservoir through the dam spins the blades of a giant turbine.
- The turbine is connected to the generator that makes electricity as it spins.
- After passing through the turbine, the water flows back into the river on the other side of the dam.
