One of the most promising forms of obtaining renewable energy is through harnessing the natural energy that is contained by waves emanating to shore from large bodies of water, such as seas or ocean coasts. There are several reasons why this energy is so promising, mainly because it is overwhelmingly abundant throughout our oceans, and because high tides, low tides, and weather patterns that would create large movements of water through natural cycles and storm surges are very predictable in their occurrences. The only question still up in the air about obtaining wave energy is if the world can find a way to make it economically reproducible and worthwhile. This mainly depends on the development of efficient technology and design in

Wave Activated Bodies (Attenuators). (Shown below respectively.)
In oscillating water columns, several chambers that function as caissons, enclose a large amount of water with a gap on the side that faces the larger body of water. When waves reach the chambers, the air column contained within becomes alternatingly compressed and decompressed. This changing air pressure is harnessed in order to spin a turbine contained within the top of the chamber, using a transmutation of the energy into a usable form. In overtopping devices, an angled ramp is used to bring waves to a height where they can drop into an elevated (relative to sea level) reservoir right behind the plate. The difference in height between sea level and the captured water within the reservoirs creates potential energy that can be harnessed kinetically by draining the water through low head turbines back to sea. …show more content…
Totaling up these figures, this means that the SSG has an overall expected wave to wire efficiency of 25 to 35 percent.
The Wavestar machine is a wave energy converter system that has already been designed in 2000, constructed, and thoroughly tested. It has been in use and feeding electrical energy to Denmark’s grid from the North Sea since 2010, streaming live data online for all the world to see its performance under an array of tidal conditions off the shore of northern
Denmark. Wavestar is a form of a wave activated body, fixed to shore and the sea floor instead of free-floating. It could also be considered a multi-point absorber as well as a wave attenuator.
This system uses massive buoys (floats), attached to 12 meter long arms that rise and fall with the incoming waves. When the floats rise or fall using the wave energy, hydraulic systems transfer the energy into rotational energy that can be harvested by a generator to produce electricity. Model testing has shown that the system is likely to produce energy from fluctuations around 90 percent of the time it is operating, and will be producing maximum
power at least 30 percent of its operational time. Waves run under the entirety of the
