Transcript of Grade 5 Energy Project (Hydro-Electric)

Hydro-Electric Energy Grade 5 How it works! Historical facts History of Hydroelectricity The Turbine is born Thank you for watching our slide show :) Micro-hydro systems The Generator The Dam The Turbine Disadvantages of hydroelectricity Benefits of hydroelectricity The power of Hydroelectricity! - No pollution or waste produced. - Building the dam is expensive and time taking. - As you can see the flow of natural water flows through the Wicket gate and turns the blades and creates energy. - From the momentum of the flow of water that turns the turbines blades it causes the shaft to spin. - Hydroelectric power can be produced on a small scale which is called micro-hydro systems. - The turbine was created by non-other than Lester A. Pelton. By: Lemuel L. and Liam Gobin What is hydroelectricity? - Hydroelectric power comes from the flow of natural water. - The energy is produced by the flow of water turning the blades of a turbine. - The turbine is connected to a special generator that turns energy into electricity. - Very reliable energy source. - Not expensive to maintain once the dam has been built. - Water can be stored, waiting to be used in peak times. - The dam will change the habitat and landscape upstream, as much more land will be submersed. - The land below the dam is also effected as the flow of water is reduced. -The turbine is connected to a shaft which turns inside the generator creating electricity. - Inside the generator the shaft makes magnets spin inside wire coils and therefore produces electricity. - All the water is in the reservoir. In case of a flood there is an control gate to help control the current. - The water then goes to the Penstock and goes straight to the turbine. - Micro-hydro systems have been used for small communities who want to produce their own electricity. - Almost 2,000 years ago the Greeks used waterwheels to help make flour by grinding wheat. - In the 1700 people used hydro power for the milling of lumber and for wheat as well. Another Example is... -Lester was born in 1929 in Ohio, and they say that he created the turbine by an accidental observation. - Thanks to him we have hydro power: A reusable energy.
