Which of the following sources of energy makes use of floating generators for its exploitation?

Wave energy is tapped by floating generators that bob on the ocean surface and convert wave motion into power.

Tidal energy is captured by barrages and turbines fixed across estuaries, not by free-floating units.

Wind energy uses tall fixed turbines on land or seabed foundations, not floating wave devices.

OTEC plants exploit the temperature difference between warm surface and cold deep water, not surface bobbing.

The up-and-down heaving of buoys drives hydraulic or linear generators to produce electricity.

Wave energy is a renewable marine source with high potential along long open coastlines.
