A classic example of renewable energy is wave energy. Wave power uses electricity generators on the ocean surface to tap into the huge store of kinetic energy. Wave energy, also known as ocean energy or sea wave energy, is energy harnessed from the ocean or sea waves. The rigorous vertical motion of surface ocean waves contains a lot of kinetic (motion) energy that is captured by wave energy technologies to do useful tasks, for example, generation of electricity, desalinization of water and pumping of water into reservoirs.
As the wind passes over the surface of the oceans, a portion of the winds kinetic energy is transferred to the water below, generating waves.The kinetic energy of the wave turns a turbine attached to a generator, which produces electricity.The wave energy is absorbed by radiating a wave with destructive interference to the incoming waves. Buoys use the rise and fall of swells to generate electricity in various ways including directly via linear generators, or via generators driven by mechanical linear-to-rotary converters or hydraulic pumps.
As you maintain height, the amount of air above you reduces, lowering the pressure. When the pressure drops, the air molecules spread out more (air expands) and the temperature decreases
