“…The assessment of available marine energy resources can be theoretical (i.e., gross-averaged energy available), technical (i.e., energy that can be extracted by a particular technology), or practical (i.e., energy that can be extracted considering practical factors, including site restrictions and constraints) [2][3][4].…”

“…Often, the theoretical and technical approaches for ocean energy assessment are related to the use of analytical, numerical, and experimental methods to estimate the power potential and identify potential sites for the installation of devices. However, in the practical stage, which must be performed through in-site studies, ecological, economic, and social restrictions often limit the complete evaluation of the resources [4]. In the last decade, research on the estimation of marine resources has greatly increased around the world.…”

“…In the last decade, research on the estimation of marine resources has greatly increased around the world. Examples of this kind of research include: energy from waves [4][5][6][7][8][9][10][11][12], ocean currents [13][14][15][16], salinity gradients [17][18][19][20], and thermal gradients [21][22][23]. Other works concerned with energy resource assessment for specific countries, such as Korea [24] and Colombia [25], have also been published.…”

The Atlantic and Pacific coasts of Mexico offer a variety of marine energy sources for exploitation. Although the Mexican government has made important efforts to reduce its dependence on fossil fuels, national participation in clean energies is still limited in terms of electricity production. This paper presents a practical theoretical assessment of marine energy sources around Mexico, with the aim of identifying potential zones for subsequent, more detailed, technical evaluations and project implementations. The energy sources considered are ocean currents, waves, salinity, and thermal gradients. Using global databases, the percentages of energy availability for the defined thresholds were computed to establish the prospective regions with the most persistent power availability. This approach proved to offer more meaningful information than simple averaged values. Moreover, some environmental and socio-economic factors to be considered for future ocean energy resource assessments in Mexico were also discussed. The results show that the wave energy potential is highest in the northwest of Mexico (~2–10 kW/m for more than 50% of the time), and that there is a constant source of ocean current energy off Quintana Roo state (~32–215 W/m2 for more than 50% of the time). The thermal gradient power is more persistent in the southwest and southeast of the country, where ~100–200 MW can be found 70% of the time. The salinity gradient energy is strongest in the southeast of Mexico. The practical approach presented here can be extended to perform preliminary resources assessments in regions where information is scarce.

The harnessing of renewable sources of marine energy has become a promising solution for a number of problems, namely satisfying the increasing demand for electricity, the reduction of greenhouse gas emissions, and the provision of energy to regions unconnected to a national grid. Tropical countries have an interesting dichotomy: Despite their varied potential sources of marine energy, their environmental and social conditions impose severe constraints on the development of a renewable energy industry. Moreover, the exploitation of these opportunities is limited by national economies' reliance on fossil fuels, political and social restraints, and technological immaturity. The present work addresses challenges and opportunities common to wave energy implementation in tropical nations, as a first approach to a regional diagnosis. The motivation for this work is to encourage research on wave energy policies in the Tropics. Technical, environmental, and social challenges to be overcome in wave energy projects are discussed. The technical challenges are grouped into development, deployment, and operation stages of wave energy converters; environmental challenges are divided into biodiversity, cumulative effects, and monitoring aspects, whilst social issues include population growth and energy access matters. The Mexican strategy for developing sustainable technology throughout the wave energy production chain is also presented. 2 of 21 projects and plans for future development based on their local marine characteristics and geographical region; temperate, polar or subpolar. Most developing countries, on the other hand, are located in tropical regions (approximately between latitudes 23.5 • N and 23.5 • S), where it may also be possible to harness marine energy. In these regions stable, high temperatures and air humidity are generally found, although climate variations exist between sub-regions, due to altitude, topography, winds, ocean phenomena, geomorphology, vegetation, and anthropic changes [13].While the greatest wave energy potential is found outside the Tropics, some tropical countries have lower, but persistent, availability of resources. Indeed, wave energy converters have been successfully deployed in Indonesia [14,15], the Philippines [16], and India [17]. Recently, evaluations of ocean energy resources in tropical regions have been published. In Asia, Purba [14] evaluated the possibilities of taking advantage of ocean energy resources in Indonesia. Through database analyses, they found sites at which ocean surface waves have a mean 72 kW/m 2 available.Regarding Oceania, Hemer et al. [18] showed that some of the most energetic wave and tidal energy resources are found in the tropical and subtropical regions of this continent. SEA [19] reported that converting energy from waves is feasible along the coast of Southern Africa [20].In the tropical regions of America, Osorio et al.[21] estimated the available ocean energy resources from waves, tides, currents, salinity gradients, and thermal gradients in Colombi...
