“…Therefore, given S(f, 8) as the directional wave spectrum in m2/Hz rad, then the nondirectional wave spectrum S(f) is in m2/Hz and can be calculated as follows: The term "nondirectional spectrum" here is referred as the "nondirectional wind wave sea surface elevation variance density spectrum," which is the integral of the directional wave spectrum over all directions (dO) at each frequency.…”

This paper gives an overview of wave resource modeling techniques and applies a methodology to esti mate the naturally available and technically recoverable resource in a given deployment site. The methodology was initially developed by the Electric Power Research Institute (EPRI), which uses a modified Gamma spectrum to interpret sea state hindcast parameter data produced by National Oceanic and Atmospheric Administrations (NOAA's) Wavewatch 111. This Gamma spectrum is dependent on the calibration of two variables relating to the spectral width parameter and spectral peakedness parameter. In this study, this methodology was revised by the authors to increase its accuracy in formulating wave length. The revised methodology shows how to assess a given geographic area's wave resource based on its wave power density and total annual wave energy flux.

“…Simulations were performed, and the simulation results were compared with results obtained from the prototype tests [76][77][78]. Some simulations and numerical analyses were performed in conjunction with laboratory-scaled tests for validation purposes [69,74,79]. The latest sets of simulation were performed to study existing devices and to help increase the efficiency of the existing devices through optimization.…”

The level of awareness about ocean wave energy as a viable source of useful energy has been increasing recently. Different concepts and methods have been suggested by many researchers to harvest ocean wave energy. This paper reviews and compares the efficiencies and power performance of different wave energy converters. The types of analyses used in deriving the reported efficiencies are identified, and the stage of the power conversion processes at which the efficiencies were determined is also identified. In order to find a common way to compare the efficiencies of different technologies, the hydrodynamic efficiency in relation to the characteristic width of the wave energy converters and the wave resource potential are chosen in this paper. The results show that the oscillating body systems have the highest ratio in terms of the efficiency per characteristic width, and overtopping devices have the lowest. In addition, with better understanding of the devices' dynamics, the efficiencies of the newer oscillating water column and body systems would increase as the potential wave energy level increases, which shows that those newer designs could be suitable for more potential locations with large variations in wave energy potentials. At last, discussion about the cost of ocean wave energy is presented as well.

More than 80% of electric power production throughout the world originates from the fossil fuelled plants. In accordance with the anticipation for increase in the demand for electricity, there is certainly a need to determine a new method to utilize renewable sources for extracting electric energy through renewable sources. In today's world, the supply of renewable electric energy is found to be one of the significant priorities within numerous parts of the world. The significant proof of this incorporates the last agreement at Marrakech 2002 and the Kyoto declaration during 1997. Both the US and EU have already developed their focus on the future emissions of greenhouse gases. It should be noted that ocean waves makes a representation of a significant source of unexplored renewable energy. Within the EU, the potential of wave energy has been conservatively estimated as 120-190 TWh per year within offshores emulated by some additional 34-46 TWh per year within near shore locations. Moreover, such anticipations rely on presumptions of energy and technology cost. And, the genuine resource would get to be notably larger. In this particular case, it can be found to be a challenging task for converting such boundless energies within the ocean waves to the electric energy. However, a considerable attention should be paid to the economic constraints for the purpose of approaching future production of sustainable electric power production for the future. This study will discuss relevant aspects for the climate change which is found to be a global threat to the entire world. For this it is quite obvious that one of the significant cause of this is the emission of carbon within the atmosphere. For this global threat, there are numerous causes and one among them includes the emission of greenhouse gas as mentioned earlier. The study will also discuss as to how wave energy can be used to allow prevention of the carbon emissions within the atmosphere. Other than that, there would be appropriate discussions on the energy devices, policies, and protocols, regional and international developments.
