Hydroelectricity

Hailey Montville

Period 6

April 19, 2011

why i chose it
Why I chose it…
  • I chose to use hydroelectricity because it is the most common form of alternative energy, and also has almost no negative affect on the environment
  • It produces no direct waste and little greenhouse gas
  • The world's hydropower plants release a combined total of 675,000 megawatts, the energy equivalent of 3.6 billion barrels of oil
  • Because Tonopah is a little community, only a small plant would be built, contributing almost no waste to the environment
building materials
Building materials
  • A dam or hydropower plant would have to be built
  • Alternative ways to build these could be, underground plants or Run-of-the-river hydroelectric stations
  • Both of these run underground and require reservoirs
pro s
Pro’s
  • The dams can store rain water
  • Controls flooding and the lakes can provide a place for recreational activities
  • Its renewable and inexpensive
  • If needed, they can be shut down quickly
  • Very few breakdowns
  • Doesn’t harm the environment
  • If this was our main source for the school, we would save money and it wouldn’t harm us
con s
Con’s
  • Dams can be expensive to build
  • If it breaks it can cause a massive flash flood
  • The plant decay caused downstream of dams can cause greenhouse gases
  • Droughts can cause a dam to be useless or produce less energy than planned
  • If this was the main source of energy for the school, there could be many breakdowns causing us to have little electricity
