Wave Power: Generating Electricity From Ocean Waves (PPT)

Generating Electricity From Ocean Waves

Wave Energy also is known as Ocean Wave Energy, is another type of ocean-based renewable energy source that uses the power of the waves to generate electricity. Unlike tidal energy which uses the ebb and flow of the tides, wave energy uses the vertical movement of the surface water that produces tidal waves. Wave power converts the periodic up-and-down movement of the waves of the ocean into electricity by placing equipment on the surface of the oceans that captures the energy produced by the wave movement and converts this mechanical energy into electrical power.

Wave energy is actually a concentrated form of solar power generated by the action of the wind blowing across the surface of the water of the ocean which can then be used as a renewable source of energy. As the sun's rays strike the Earth's atmosphere, they warm it up. Differences in the temperature of the air masses around the globe cause the air to move from the hotter regions to the cooler regions, resulting in winds.

Sea waves have high energy densities, the highest among renewable energy sources with the natural seasonal variability of wave energy following the electricity demand in temperate climates securing energy supplies in remote regions. Wave energy also has negligible land use and large-scale implementation of wave power technologies could help stimulate declining shipbuilding and dockyard industries that could help fabricate these metal-bodied wave energy devices.
