The socio-economic interactions of marine renewable energy development and the commercial fishing industry on the island of Ireland
The global increase in energy demand and the need to reduce carbon emissions necessitates the use of alternative sources of energy such as marine renewable energy (MRE). For the purpose of this thesis, MRE refers to offshore wind, tidal and wave energy. The island of Ireland, comprising the …
