There is growing interest in Europe and North America in locating wind farms in ocean space within national jurisdiction. For many States, wind is the renewable energy of choice in the search for alternatives to fossil fuels to meet emissions reductions targets established by international agreement on a large scale. Locating windfarms in the marine environment is attractive because of the availability of open spaces to accommodate extensive arrays capable of producing power on a large scale, ideal wind conditions and less likelihood of impacts that trigger public opposition, such as noise, lowering of property values and interference with landscape aesthetics.
