Which energy source relies on the gravitational pull of the moon and sun?

Tidal power is generated by harnessing the energy produced by the gravitational pull of the moon and the sun on Earth's oceans. This gravitational interaction causes the rise and fall of sea levels, leading to tidal movements. By constructing tidal power stations near coastal areas, energy can be extracted from the kinetic energy of moving water as tides flow in and out. This form of energy production is predictable and sustainable, making it a reliable source of renewable energy.

Other energy sources listed, such as wind, hydroelectric, and wave power, rely on different forces and phenomena. Wind power harnesses the energy created by air movement, hydroelectric power is generated from the flow of water in rivers or dams, and wave power takes advantage of the surface movement of water due to wind. Each of these sources operates based on distinct principles and mechanisms, unlike tidal power, which is directly influenced by lunar and solar gravitational effects.
