Question: How does a tidal power station generate electricity?

Answer: The way a tidal power station generates electricity is actually quite simple. Imagine that you have two bodies of water separated by a wall. Built into this wall below the water is a tunnel connecting both sides with a turbine in it. If you raise or lower the water level on one side the water will flow to balance out with the other side. This flow will turn the turbine which powers an electrical generator thus producing electricity. In tidal power stations one of the bodies of water is the ocean and the other is a man made reservoir. Just letting the tides come and go will produce electricity but in addition to that sometimes gates will be used to keep the reservoir at “low tide levels” when the ocean is at high tide and the opposite as well. This gate is then opened allowing the levels to equalize and then closed again until the peak low or high tides come again when the process repeats itself.
