What is tidal energy?
* Tidal Energy is the utilization of the variations in sea level cause primarily by the gravitational effects of the moon, combined with the rotation of the Earth.
* Tidal power is a way to generate electricity by taking energy from the sea.
* Tidal power generation works differently to hydro-electricity, and wave power.
* The tides contain energy that can be harnessed to produce electricity
Some Tidal Plant’s are:
* Tidal Fences are fences that block any channels that forces water to go through it and turn it’s turbines to generate electricity.
* Barrage Tidal ...view middle of the document...
* A huge dam called a “barrage” is built across a rive estuary, and when the tide goes in and out, the water flow’s through tunnels in the dam.
* Once you’ve built it, tidal power is free
* It produces no greenhouse gases or other water
* It needs no fuel
* It produces electricity reliably
* It is not expensive to maintain
* Tides are totally predictable
* Offshore turbines and vertical-axis turbines are not really expensive to build and do not have a large environmental impact.
* Only provides power for around 10 hours each day, when the tide is actually moving in or out.
* A barrage across an estuary is very expensive to build.
* It affects a very wide area by taking up all the space for the tidal generation
* Fishes can migrate unless “fish ladders” are installed.
* Birds rely on the tide uncovering the mud flats so that they can feed.
* It is expensive to construct
* There are limited construction locations.
* Tidal Energy is renewable because the tides will continue to ebb and flow, and the energy is there for the taking.
* The largest tidal power station in the world is in the France estuary in the northern France, near St. Malo.
* Tidal Energy has the potential to become a successful option for the large scale.
* Tidal Streams are the most attractive method, because it has reduced environmental and ecological impacts and being cheaper and built in quicker.
