Tidal PowerBy: Randi Smith

Shelbi Martin Paul Aproian

● 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

● Reduce your carbon footprint● Low running cost

Why invest?

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

● 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.?

● 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?

● 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?

Pros and Cons?

pPros 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
