1. Hydropower By: Dominic Imwalle, Jason Rebholz, Zack Berwald

2. Formation • Hydropower is energy from moving water • The movement of water between the earth and its atmosphere is in a continuous cycle. • When sun draws moisture from oceans and rivers its called evaporation • Then the moisture condenses into clouds which is called condensation. • After that the moisture is released from the clouds which's called precipitation then it starts back over

3. History • In year 1087 A.D five thousand water wheels were made in France • Water wheels were used to grind flour and grain for 2,000 by the Greeks • The first hydro plant was built at Niagara Falls. • Ancient Egyptians first used waterwheels on Nile river in early 200 B.C • 1700s factories of industrial revolutions used water to power machines

4. Obtaining • Over 80,000 dams have been built in the U.S • The top hydro plant state is in Tennessee with five hydro plants • Towers carry energy from a generator in a Dallas Dam

5. Advantages • An advantage is that hydropower is renewable • Snow and rain replenish hydropower • hydropower is one of the cheapest energy sources

6. Disadvantage • There are 80,000 dams in U.S but only 2,400 generate electricity • Dams in U.S built to control flooding wind irrigate farmland, not for electricity production • Depending the amount of rainfall during year provides between 5 and 10 percent of country electricity • Roads in community's have to move when dam is being built

7. Current and Future conservation Hydropower is renewable and is replenished by snow and rainfall

8. Future Technology • One idea is to make under water wind mills • Cars might use water as gas by adding hydrogen and oxygen gas • Make more chain bobbling ducks to span part of Estorny Mouth, making wave energy into energy into electricity
