Final answer:
Tidal power plants use kinetic energy from the rise and fall of tides. This causes movement of turbines, which create usable energy.
Step-by-step explanation:
Tidal power plants harness the kinetic energy generated by the rise and fall of tides in coastal areas. This natural phenomenon creates the movement of water, which is utilized to turn turbines. These turbines are strategically placed in the path of the moving tidal waters. As the tide rises and falls, the water flows over and around the turbines, causing them to rotate. The rotational movement of these turbines is then converted into usable electrical energy through the operation of generators.
In essence, the kinetic energy of the moving water, driven by the tidal forces influenced by the gravitational pull of the Moon and the Sun, is captured by the turbines and transformed into electricity. This renewable energy source is both predictable and eco-friendly, making it an attractive option for sustainable power generation in coastal regions with significant tidal fluctuations.
