In what way is tidal energy harnessed?

Tidal energy is harnessed by capturing the movement of water caused by the rise and fall of tides. This involves using turbines that are placed in areas where the tidal flow is strong. As the tide comes in and goes out, the flowing water moves the turbines, which then convert the kinetic energy of the water into electrical energy. This method takes advantage of the natural gravitational pull of the moon and sun, responsible for creating tidal patterns.

The other methods mentioned in the options do not apply to tidal energy: solar panels are used for capturing solar energy, wind turbines harness energy from wind, and capturing heat from the Earth refers to geothermal energy. Each of these sources operates on different principles that do not involve the tidal movements of water.
