The selection of the appropriate wave energy converter (WEC) and site is the basis for the installation of a wave farm in a region. For this purpose, the estimation of the energy that any WEC would produce at any location of interest is fundamental. Despite all its importance, this information...

This paper presents the analysis of the intra-annual power performance of different WECs (wave energy converters) at two locations of interest in the northern coastal region of Galicia (NW Spain). With this aim, the wave resource at the locations of interest is characterised by considering a...

In many regions strong tidal flow occurs only in areas with restricted water depths, typically within estuaries or rias. Although in some of these areas the depth constraint may preclude the exploitation of this resource, in others it is exploitable – and substantial. The objective of this...

The estimation of energy production of a given WEC (wave energy converter) at a given coastal site is the basis for correct decision-making regarding wave energy exploitation in a coastal region. Nevertheless, the procedure followed by the conventional approach to characterize the wave energy...

During the last years the interest of supplying the energy needs by means of renewable energy sources has risen sharply. The objective of this work is to investigate the viability of the implementation of a tidal farm to fulfill the electricity demands of the Port of Ribadeo, which is located in...

When planning the installation of a tidal farm, the disturbances on the marine environment associated with its operation must be studied in detail. The objectives of this paper are to assess the impacts on the hydrodynamics (water level and flow velocity) and to determine how these impacts can...

In a tidal stream project the selection of the most appropriate device is of major importance. The aim of this work is to investigate the difference between two tidal farms, one with floating TSTs (Tidal Stream Turbines), the other with bottom-fixed TSTs, in terms of annual performance and its...

The interest in the exploitation of the tidal stream energy has increased significantly over the last years and several tidal farms have been proposed. In spite of this, only a few studies dealt with the potential impacts on the environment resulting from the extraction of this energy, most of...
