Tides/Waves Power Allie Henning Anneliese Sparks

Uses Used for Electricity

How It Produces Energy Tidal energy is generated by the relative motion of the Earth, Sun and the Moon Tidal stream generators draw energy basically the same way as wind turbines no standard technology for capturing the power yet but a variety of designs are being experimented with

Dam Method/Tidal Barage Used in mostly England A huge dam (called a "barrage") is built across a river estuary When the tide goes in and out, the water flows through tunnels in the dam. The flow of tides can be used to turn a turbine, or it can push air through a pipe, that turns it

Buoy Method Used for Wave power mostly in New York Power Buoy uses the rising and falling of the waves to generate power Power is transmitted to the shore from underwater cables

Advantages Over Non-renewable Resources Earth's tides are caused by the tidal forces from gravitational pulls from the Moon and Sun, and the Earth's rotation, tidal power is practically inexhaustible

What it could Replace Would replace wind and solar power because –More predictable –higher density of water, 832 times the density of air –water speeds of nearly one-tenth of the speed of wind provide the same power for the same size of turbine system

U.S. Locations Washington Oregon San Francisco Santa Cruz New York (East river) Mississippi River Hawaii Maine Massachusetts Oregon California Washington (Gray Harbor)

Pros Cons ocean energy is dense and extremely predictable. The size/energy of waves can be known anywhere from 3 to 5 days in advance. Tides are very predictable because they’re based on the moon Cost of technology likely to fall harsh environment not proven on commercial scale environment/marine safety issues technology is currently priced high limited geographically Tide power can only be used when it’s going in or out (10 hours a day)

Is it Likely to Become Mainstream?  It is likely to become mainstream because we’re covered with 97% water and European countries have done a lot with it can influence the United States to consider more.

Infrastructure Michigan would Need Need Money Need stronger waves/tides
