Kinetic Energy: The Pros And Cons Of Ocean Energy

Ocean Energy

Argument 1:

Renewable: because it will never run out, it will help us to achieve our renewable energy and energy derived from the sea including wave energy, tidal energy, river current, ocean current energy, offshore wind, salinity gradient energy and ocean thermal gradient energy

Argument 2:

Easily Predictable: wave power as against most of the other alternative energy sources is that

it is easily predictable and can be used to calculate the amount that it can produce.

Argument 3:
No Damage to Lands: the turbines move very slowly they don’t move very fast.The turbines are much heavier making them move very slowly so very little to no damage is done to the marine life.

Introduction:

Ocean energy

Ocean energy It’s a renewable energy resource, but not only, along the Atlantic seaboard. Ocean energy are currently being developed to exploit tides and waves. Ocean energy technology as a source of renewable energy, are significant in the United States.

Wave Energy

is the motion of waves is harnessed and converted from mechanical energy into electricity

takes advantage of the ocean waves, Wave energy is a form of renewable energy that can be harnessed from the motion of the waves.

Wave energy is a conversion that takes advantage of the ocean waves caused by interaction of winds with the ocean surface. Wave energy is an irregular and oscillating low-frequency energy source that must be converted to a 60-Hertz.

many wave energy devices have been invented, only a small proportion have been tested and evaluated.in ocean waves, rather than in artificial wave tanks.

Tidal

Energy
they can be trapped in reservoirs behind dams. is a form of hydropower that converts the energy obtained from tides into useful forms of power.
when the tide drops the dam can be let out just like in a regular hydroelectric power plant. Small dams were built along ocean estuaries and small streams. the tidal water behind these dams was used to turn water wheels to mill grains.
"Ninety percent of today's worldwide ocean energy production is represented by a single site: the La Rance Tidal Power Plant
Ocean Thermal Energy Conversion (OTEC)
temperature differences in the ocean. Power plants can be built as different temperatures to make energy.The cold ocean water can also be used to cool buildings, and desalinate water if it’s often a by-product.
Using this type of energy source is called Ocean Thermal Energy Conversion or OTEC. It was demonstrated in Hawaii at the Open Cycle Ocean Thermal Energy Conversion (OC-OTEC) system located at the Natural Energy Laboratory of Hawaii Authority (NELHA) at Keahole Point on the Big Island of Hawaii.

The physical oceanic energy sources are:

tides (hours to days)
waves (days to months)
currents (months to decades)
temperature differences (decades to millennia).
