Tidal power hasn't got a large environmental impact. The tidal power don't let fish and large marine animals migrate because the frames of the turbines could kill fish population when they are passing through. There is as well a possibility of noise that could cause pollution.
Iris: Can it be used in the Netherlands or in Spain, and why?
Can it be used in the Netherlands or in Spain, and why? Yes, it can be used here. In both lands is enough water and the generator needs to be in the water. Maybe you think now, why does it needs to be in the water? Now that is because the water is 832 times denser than air, so that means that an 8 knot tidal current has more energy than a 380kph wind. But it is also more predictable and that is nice because you can predict how much energy will be produced. So, now you know why it is more handy to have the generator in the water. But the water needs to be of course, deep enough. At the beach is always not immediately very deep. And the generator can be 2 squared meters - 100 squared metres, so you can't place it there, and it wouldn't be safe to because there swim people. So it needs to be further into the sea.
Jaime: Where can you find these plants and why?
The power plants in Spain are: Motrico (Guipúzcoa) and Santoña (Cantabria). The power plants in Holland are: (No have)
You can find the power plants in this place because there's tidal.
Stan: How does it work?
Subject: How does it work?
Tidal power is not used very much because it is very expensive, but if it is used it generates lots of electricity. Tidal power is used in the water and with turbines. The turbines can be as big as 2 m2 to 100 m2. the biggest turbine in the world has cost 3,15 billion. If there is coming water through the turbines, the turbines start to run and electricity is generated. The bigger the turbine the more electricity is generated. Also tidal power gives much more energy than wind power.
