What Tidal Energy is and its History.
tidal energy is a from of energy that comes from underwater. people around the world use tidal energy every day and power many different energy sources. Tidal power can be harnessed using a barrage (dam) built across an estuary that captures the potential energy generated by the change in height (or head) between high and low tides. As the tide goes in and out, the water flows through tunnels in the dam. The ebb and flow are used to either turn a water turbine or compress air through a pipe that then turns a turbine, which generates electricity.
As you probably already know, tidal energy is using the shifting of the ocean’s tides to generate some form of energy. This was done in 900 A.D. by using naturally-occurring basins close to the ocean, and building a barrage (or dam) across the opening. The basin would fill when the ocean’s tide rises, and would empty when the tide lowered. Usually when the tide would come in to the basin it would spin one water wheel, and spin a different one when it drained back into the ocean
The tides will continue to flow, thus there will always be power being generated. the water isnt used up, it stays in the water cycle, and can there for be used over and over again without the need for replacement.

Pros and Cons
Pros Cons
-non-pollution type of energy -Tidal power is expensive
-no global environmental impact - storage or grid-backup required
-requires no flue - this kind of energy can reduce kinetic energy
-renewable source of electricity - has an impact on marine life
-relibal plant because it can last
up to 100 years - it captures dirt, pollination and near waist from the shore and brings it into the ocean
