Tidal Energy

Tidal Energy

This is an average tidal compost.

Advantages:Apart from the initial installation cost, tidal power is free.Tidal energy produces no greenhouse gases or any other kind of pollution.It requires no fuel.Disadvantages:A barrage across an estuary is very expensive to build, and affects a very wide area.The environment is changed for many miles upstream and downstream.Many birds rely on the tide uncovering the mud flats so that they can feed. Fish can’t migrate, unless “fish ladders” are installed.

The history of tidal power stretches into antiquity. The earliest evidence of the use of the oceans’ tides for power conversion dates back to about 900 A.D., but it is likely that there were predecessors lost in the anonymity of prehistory. http://www.tidalelectric.com/technology-history.shtml

Alot has changed in the last 5 years, as how they can make the energy by using different techniqures to add wave power to the turbines.http://education.nationalgeographic.com/education/encyclopedia/tidal-energy/?ar_a=1

How Tidal Energy is used today is to light up peoples home in britan mostly! Crazy how much just waves can do!
