1. Tidal Power By: Randi Smith Shelbi Martin Paul Aproian

2. ● The U.S. Department of Energy is investing $16 million on 17 different projects to help capture energy from waves, tides, and currents. Current N.Y./U.S. investment

3. ● Reduce your carbon footprint ● Low running cost Why invest?

4. The following three projects are in development in Wales where tidal ranges are high, renewable source power is a strong public policy priority, and the electricity marketplace gives it a competitive edge: ● Swansea Bay 30 MW ● Fifoots Point 30 MW ● North Wales 432 MW Latest Scientific Advancements

5. ● More than 300 hydroelectric generating stations ● Some are very small and some are very large, but most are generally in between. How many tidal plants in N.Y.? U.S.?

6. ●Estimates say that when combined with hydropower and other water-based resources, tidal power could help to account for up to 15% of the U.S. electricity supply by 2030. ●The U.S. receives 2,100 terawatt-hours (1 billion kWh) of incident wave energy along its coastlines each year. How much electricity is generated?

7. ● Tidal energy has the potential to power 15 million homes ● Saves 70 million tonnes of carbon ● Created 16,000 jobs in the UK alone ● Tidal turbines are located beneath the ocean surface and cannot be seen or heard ● Water is 830 times denser than air meaning that, for an energy output, tidal turbines can be much smaller than wind turbines Why is it better?

8. Pros and Cons? p Pros Cons ●High Efficiency ●Emission-Free ●Reliable, a plant can last 100 years ●Predictable output ●Could potentially provide a storm surge barrier ●Environmental impacts are local, not global ●Expensive to Build ●Locations are often remote ●Disrupts regular tidal cycles ●Reduces kinetic energy in the ocean ●Decreases salinity in tidal basins ●Captures dirt, waste and pollution near the coast ●Barrages may restrict access to open water
