  1. Hydroelectricity A learning experience by B-P Frank Bilotto and Damon Lee

  2. How does it work?

  3. How does it work? Cont… • Water is stored in the reservoir on the other side of the dam. • Water comes through a penstock and spins a turbine • The turbine turns the generator rotor, which creates energy in the same matter of other electrical generators.

  4. Where are these plants found? • Hydroelectric dams are primarily found in areas with significant elevation difference and good water flow.

  5. Pros Cons Produce inexpensive and clean energy Dams can break down in flash flood Dam stores water in case of drought Requires the flooding of entire area Plants can shut down instantly Dams are a simple design (inexpensive repairs and maintenance) Dams and flooding disrupts seasonal changes

  6. Dams effect on environment • Decaying of the surrounding areas vegetation • Disrupts the rivers natural flow

  7. How much of this energy do we have? • Since the dams only require flowing water currents the abundance of materials for this energy is unlimited.

  8. What pollutants are created? • In construction of the dam, only some minor pollution is cause by machinery and disposal of materials. • Other than that the pollution of hydroelectricity dams are slim to none.

  9. What is the cost to maintain these dams? • The cost of constructing one of these dams is anywhere from $850,000 to $1,200,000 • The cost to maintain one of these dams is only about 3 to 5 cents an hour. Depending on how much energy it creates.

  10. Research Point: 1 • The effects of near by towns by tax money that help schools and the overall communties.

  11. Research Point: 2 • These dams supply 9% of the U.S electricity source. • It accounts for 49% of renewable energy in the U.S
