Ocean Energy

Scientists and innovators are working to harness the massive amounts of energy created from ocean waves and currents.  Ocean energy is the kinetic energy of moving water created naturally by the Earth’s rotation and gravitational forces. Different methods can be employed to harvest this kinetic energy and convert it into electricity. Ocean energy is yet another clean and sustainable source of energy. If it can be harvested on a large enough scale it may be able to compete with solar and wind power.

Ocean energy usually refers to two types of energy created by the ocean.  Wave power is the kinetic energy created by waves on the surface of the water.  Tidal power is kinetic energy created by the movement of large bodies of water. Wave power is harvested using "wave energy converters". The kinetic energy from the waves is converted into electrical energy through the use of turbines and generators. One disadvantage is the noise pollution created by the large underwater turbines and generators. This noise pollution can potentially cause a disruption to local marine life which can have far-reaching effects.

One benefit to tidal energy is the ability of aquamarine scientists to accurately predict tidal power.  This is not the case with solar and wind power as weather patterns are constantly changing.  Through proper calculations accurate estimates of the amount of electricity production can be made.  Turbine fields harvesting tidal power are also out of eyesight and do not use up valuable land.

However, tidal power plants can be costly to build due to their location. Not all areas close to the ocean have access to tidal energy that is powerful enough to generate large enough amounts of electricity.  Tidal power plants are also susceptible to damage from whirlpools.  Although there is much energy available in the ocean, harvesting it and converting it to electricity presents many challenges and obstacles.
