  1. Hydroelectric Power Earths Energy Needs By Hannah M., Julia K., and Sam C.

  2. Hydropower generates electricity by water. It is one of the oldest sources of energy because it was used thousands of years ago to turn a paddle wheel for purposes such as grinding grain. Until 1880 coal was the only source of fuel to produce energy and coal is very bad for the environment.

  3. Hydropower works by a turbine converting the kinetic energy of falling water into mechanical energy. Then a generator converts the mechanical energy from the turbine into electrical energy.

  4. Lester Allan Pelton Lester Allan Pelton invented the fist water-powered energy, the water-wheel. He was born in 1829 in Vermillion, Ohio. Later he moved to California and created the first waterwheel. He later died in 1908. To the left is his original hydroelectric plant

  5. Dams Dams are a great example of Hydropower. Dams raise the level of the river to create falling water. It also controls the flow of the water. This is an illustration of a Hydroelectric dam

  6. What Scientists Are Experimenting Within This Field Since hydropower captures the energy of falling water to generate electricity, scientists are experimenting how much electricity dams can produce depending on the size of the dam. Dams range in size from “micro-hydros” to big ones that power over 10,000,000 homes like the hover dam. Power = (Height of Dam) x (River Flow) x (Efficiency) / 11.8

  7. How We Can Apply These Ideas for Energy Conservation Hydropower is almost free, uses no waste products, and does not pollute the water. It conserves energy because it is a renewable resource and it does deplete earth of its natural recourses because it uses the motion of the water to create energy.

  8. How we can help hydropower with everyday easy work How to help hydroelectric dams. If your ever are on a boat or fishing (somewhere next to or in the water) and see a stick or something please take it out of the water because these can get stuck in the turbines and could clog the dam ending in a repair which would be quite expensive.

  9. How These Energy Needs Will Be Met In the Future We need to conserve energy so our next generation will have a clean earth. As stated before, hydropower does not deplete the earths natural resources.
