Ocean Wave Energy as an Alternative Essay

1004 Words 5 Pages
With the energy costs increasing and the available resources depleting many people are looking towards other renewable, easily derived energy resources. With this searching many people have looked toward ocean energy. Ocean energy is an ideal resource meeting the requirements people set when looking for new sources. Although the technology is still being developed and evolved, with the technology known ocean energy has already shown to be more prospective than other energy sources already in use. The resources used currently to supply power to the people of the earth are highly restricted and have constant problems. There are many alternatives available for supplying energy, that are renewable and more nature conscious. One …show more content…
Since the heat of the atmosphere creates the winds leading to the creation of waves, wave energy can be seen as a by-product of solar energy. The energy from the waves is transported long distances easily and little energy is lost. Although the energy is transported, the water is not moved. The amount of energy extracted depends on the height of the wave and the speed of the waves; the areas that have the highest energy potential are within the latitude of 40 degrees and 60 degrees, in both the southern and northern half of the hemisphere (Carless, 1993, Gallachóir 2006, Ocean Wave Energy, 2006). There are many applications to deriving the energy from waves, but the three most known are: Floats or Pitching Devices, Oscillating Water Columns, and Water Surge or Focusing Devices. The Floats are devices that stay close to the surface of the ocean and are usually attached to a raft or the ocean floor. The buoys can convert many waves, coming from multiple directions. The Oscillating Water Columns (OWC) is a pressure-activated device that is shaped as a cylindrical rod. There devices use the rising and falling of the water causes the air to be forced into and out of the top chamber. The top chamber contains a turbine, which is driven by the pressure of the air. As the wave’s rise they push the air and cause the turbine to be turned and as the waves fall the air is sucked out. The turbine always spins in the same direction so it can work
