Having in mind the increasing maturity of wave energy technology, it is opportune to investigate the main concerns and issues over the Portuguese coast to large-scale development of wave energy basically arising from competing uses of the ocean space.
In the maritime domain there are several players and entities with different interests and competences, so that it is important to try to understand and, if possible, to conciliate the different viewpoints. The experience from offshore wind energy has demonstrated that this is a difficult task, which has to be approached as early as possible. The lack of sensitivity of the entities involved in a large-scale wave energy project may in some cases generate conflicts and some concern by the communities more directly involved in the traditional activity sectors of the maritime domain. This may constitute a barrier to the realisation of a project, and to the acceptance of the technology.
In countries with significant coastline, the near-shore area has been a traditional domain of the fishermen communities and the interference with these communities can turn out to be problematic for the development and implementation of the project. This study identifies the main problems, provides a perception of relevant issues by interested parties and gives recommendations for preventive mitigation measures. On the other hand also potential benefits and opportunities of large-scale wave-energy development are briefly discussed. Successfully overcoming the non-technological barriers enables to
The main non-technical barriers are related with competing uses of navigation activities, fishing resources and, to a small extent, petroleum prospection/exploitation. Restricted areas such natural reserves, military exercises areas and submarine crossing cables need to be taken into consideration as well but are not critical in Portugal. Another aspect that may constitute a barrier to the development of wave energy projects is the public acceptance. It can play an important role for the critical path of large-scale projects and may impose serious conditioning to the time-schedule and realisation of a project. Public
 Potential for Wind Energy Utilisation in Bosnia and Herzegovina
On the base of data on wind characteristics from The Hydro and Weather Forecast Institute of Bosnia and Herzegovina, preliminary data base on wind frequencies and velocities for selected regions is created. A part of the results for Sarajevo area is
