3. To have Hydroelectricity you need constant running water. Producing this energy source you must have a lot of space for machinery used in this process.

4. Nuclear Energy Wind Energy Solar power – photovoltaic, thermal collector Coal, natural gas, petroleum (fossil fuels) Geothermal energy

5. Fuels or other minerals are not burned so there is no pollution produced To have hydroelectricity you need running water nearby. When produced water is used which comes naturally from nature. Hydroelectricity is dangerous for animals that live in the water. It can destroy fish’ habitats which reduce fish population and may result in endangering different species. Using hydro electric power reduces greenhouse gases. It is difficult to set up hydroelectric power plants Once purchased and installed it pays off. (Relatively inexpensive) Hydro electricity is reliable and renewable.

6.  Dams have potential energy of the stored water  There is Kinetic energy of the turbine as it turns when the water current rushes in.  The turbine activates the generator.  The generator provides electricity which is collected and

8. Hydro electric power is currently a popular source of energy. It is renwable and inexaustable. This means that it can never be used up and it can always be produced as long as the right equipment is used.
