Wave power: waves accompany tides. These waves can be easily harnessed to drive wind turbines which in turn produces electricity. They can also be used in wind mills.

Power from fossil fuels: Oceans contain a vast reserve of fossil fuels. Most oceans in times past are sedimentary basins that accumulates remain of organisms. As natural processes plays out, they yield fossil fuels. These fossil fuels can be tapped for use in different machines and gas power plants.
