Why ocean energy
What can ocean energy add?
Covering 70% of the planet’s surface, oceans are a source of abundant renewable energy potential. Energy harnessed from oceans, through offshore renewables, can contribute to the decarbonisation of the power sector and other end user applications relevant for a blue economy, e.g. shipping, cooling, water desalination. For countries with coastal areas and island territories, offshore renewables can provide significant socio-economic opportunities, such as job creation, improved livelihoods, local value chains and enhanced synergies between blue economy actors.
Offshore renewables include offshore wind (fixed and floating foundations), ocean energy (wave, tidal, ocean thermal energy conversion/OTEC, salinity gradient) and floating solar PV technologies. The theoretical resource potential of ocean energy ranges from 20,000 TWh to 80,000 TWh of electricity generation per year, representing 100% to 400% of the current global demand for electricity.
