TL;DR: In this paper, the authors proposed an approach based on a large number of nearshore wave patterns and applied it to the Galician Southwest, where the first administrative concession for a wave farm (at a site to be determined) is expected to be issued shortly.

Abstract: The main objectives of the present work are to review the global wave energy resources according to the most recent datasets available, to identify the locations with the worldwide highest wave energy potential and to assess in those locations the performance of some state-of-the-art wave energy converters. For this purpose, 15 years of wave data provided by the European Centre for Medium-Range Weather Forecasts, covering the time interval 2000–2014, were considered, processed and analysed. After identifying the geographical regions with the highest wave power, 15 reference points, which were considered more relevant from the point of view of their wave energy potential, have been defined in each hemisphere (northern and southern, respectively). As a following step, corresponding to all of these reference points, the most relevant wave patterns have been identified, and this information was subsequently used to assess the expected power output of the wave energy converters considered. Some other relevant parameters, such as the capacity factor or the capture width, were evaluated as well. Following the results provided by this work, we can expect that most of the existent devices for harnessing wave energy would perform well near most of the coastal environments identified. Moreover, it also must be highlighted that in the future, wave energy farms can play a very active role from the point of view of coastal protection.

TL;DR: A revised version of the selfconsistent theory of ion diffusive shock acceleration and the associated generation of hydromagnetic waves is presented in this paper, where the wave growth or damping rate is again calculated using linear theory, but a more general ion anisotropy is calculated using the pitch angle diffusion equation.
Abstract: A revised version of the self-consistent theory of ion diffusive shock acceleration and the associated generation of hydromagnetic waves is presented. The theory generalizes and corrects the theory of Lee [1982, 1983]. Lee assumed a linear dependence of the anisotropic part of the ion distribution function on the cosine of the ion pitch angle. Here the wave growth or damping rate is again calculated using linear theory, but a more general ion anisotropy is calculated using the pitch angle diffusion equation. The wave intensity satisfies a wave kinetic equation, and the ion omnidirectional distribution function satisfies the energetic particle transport equation. These coupled equations are solved numerically and compared with an analytical approximation similar to that derived by Lee. The analytical approximation provides an accurate representation of both the proton distribution and the wave intensity. A comparison is made between the predicted wave magnetic power spectral density adjacent to the shock as a function of frequency and the wave spectrum measured by ISEE 3 at the November 11–12, 1978, interplanetary traveling shock. There is excellent agreement between the predicted and measured power spectral density in the frequency range of 0.03–0.3 Hz. A comparison is also made between the predicted total wave energy density and that observed upstream of Earth's bow shock by the AMPTE/IRM satellite for a statistical survey of ∼400 near-to nose events from late 1984 and 1985. This comparison revises the result presented by Trattner et al. [1994]. The correlation between the observed wave power and that predicted, based on the observed energetic proton energy density, is very good with a correlation coefficient of 0.92. However, the average observed wave magnetic energy density is ∼63% of that predicted, suggesting possible wave dissipation which is not included in the theory.

TL;DR: Work on wave energy within the UK began in the early 1970s with a report from the Central Policy Review Staff, which identified the Government's responsibility to assess a wide range of possible energy options to ensure security of energy supplies as mentioned in this paper.
Abstract: Work on wave energy within the UK began in the early 1970s with a report from the Central Policy Review Staff, which identified the Government's responsibility to assess a wide range of possible energy options to ensure security of energy supplies The UK Department of Energy (DEn) funded extensive research into wave energy during the period 1974 to 1983 under its Wave Energy Programme The programme objectives were to establish the feasibility of extracting energy from ocean waves and to estimate the cost of energy if used on a large scale to supply UK needs The latter objective was addressed by setting a design aim to establish a 2 GW wave power station situated off South Uist in the Outer Hebrides of Scotland During the course of the programme a large number of devices were considered but found to be uneconomic (ETSU, 1985) With hindsight, the objective of that programme was over ambitious and resulted in massive devices, with corresponding high capital and generating costs
