Final answer:
Ordinary ocean waves primarily derive their energy from winds, as the wind's interaction with the water's surface creates the waves. More energy is transferred to the water when the wind is stronger, producing higher waves. Waves can also be harnessed for electricity generation.
Step-by-step explanation:
Ordinary ocean waves derive their energy primarily from winds. The interaction between the wind and the surface of the water transfers energy to the water, causing the surface to oscillate up and down. This energy transfer is more effective when the wind is stronger, leading to higher waves.
The energy from the wind helps create the up-and-down motion of ocean waves, which can then potentially be converted into electricity using technologies such as wave energy converters. Intermittency—largely seasonal—is moderate as storms and lulls come and go, impacting the consistency of wave power.
