Tidal Power
Renewable Energy
What exactly is tidal power?
Tidal power, also called tidal energy, is a form of hydropower that converts the energy of tides into useful forms of power-mostly electricity. It has potential for future electricity generation. The tides are more reliable than wind energy and solar power because they are always going- tides are controlled by the moon and we should always have a moon!
How it's renewable
- It runs off of water which is all natural :)
- it doesn't take millions of years to be restored
- it is all green so it makes energy the right way
TIDAL POWER. SAY GOODBYE TO THE OLDNESS AND HELLO TO THE GREEN EARTH!
How it works?
This picture shows you how tidal power works. The tides come in through the basin and go through the barrage. The barrage is pretty much a dam. When the water goes through the barrage the turbines take the energy from the water and the tides are put back into the sea
Examples below
pic!
this is what a tidal power plant looks like. They are pretty big and really cool. They are really long and stretch for quite some distance as you can see in the picture.
turbine
Here is an example of a turbine. The turbines are kind of like underwater wind mills. They are really REALLY big!
high tides
High tides are the main thing needed to produce tidal power. without the tides you couldn't even call it tidal power! So without the marvelous high tides this presentation would be pointless!
PROS AND CONS OF TIDAL POWER
PROS:
- Renewable. Requires no fuel.
- Emission-free
- Reliable, a plant can last 100 years
- High efficiency
- Predictable output
- Could potentially provide a storm surge barrier.
- Environmental impacts are local, not global
- Expensive to build
- Locations are often remote
- Can change tidal level of surrounding area
- Impact on fish, marine mammals and birds
- Disrupts regular tidal cycles
- Captures dirt, waste and pollution near the coast
