Harnessing the energy of tides to generate electricity is different than a hydroelectric power station at a dam because tidal energy __________.
ultimately relies on ocean currents, and hydroelectric power ultimately relies on the energy from the sun tidal energy ultimately relies on the gravity of the sun and the moon, and hydroelectric power ultimately relies on the energy from the sun uses turbines and a dam uses generators tidal energy ultimately relies on the wind, and hydroelectric power ultimately relies on the energy of rain
The correct completion of the sentence is: tidal energy ultimately relies on the gravity of the sun and the moon, and hydroelectric power ultimately relies on the energy from the sun.
This distinction highlights the different sources of energy that drive these two forms of electricity generation. Tidal energy is influenced by the gravitational pull of celestial bodies, while hydroelectric power is primarily driven by the water cycle, which is powered by solar energy.
