Tidal Energy is produced through the use of large underwater Turbines that are placed in areas with high tidal movements.

Slide 6

What are Tidal Barrages? A tidal barrage is basically a huge dam that is built across a river or estuary. Tunnels are built throughout the dam, and when the tide rises and falls it turns a turbine that generates power.

Slide 7

Advantages *Once built, tidal power is free it produces no greenhouse gases or other waste and needs no fuel. *Hydroelectric energy offers the advantage that for people using this type of energy to generate electricity, they are not dependent upon the price of uranium, oil, or other types of fuel.

Slide 8

Disadvantages Picture The rise and fall of the tide is consistent which makes it very predictable and reliable Tides do not produce a lot of electricity. Tidal energy and the advantage and disadvantage of it, the utilzation of the sun and moons gravitational.
