Offshore wind energy in Europe

Offshore wind is a highly promising renewable energy source (RES) that could make a major contribution to global and European efforts to decarbonise the economy by 2050 and keep global warming to around 1.5°C above pre-industrial levels, as set out in the Paris Climate Change Agreement. The European Commission expects the EU to produce at least 240 gigawatts (GW) of global offshore wind power capacity by 2050, while international organisations specialising in the energy field are even more optimistic about the prospects of this energy source. Europe accounts for 80 % of global offshore wind capacity and is the dominant region in terms of technologies and manufacturing. Offshore wind accounts for 210 000 jobs in Europe (over half of all jobs in wind energy), and this number should increase further with greater investment. Wind is the only offshore RES that is currently deployable on a commercial scale and there is vast untapped potential in the world's oceans and seas, even if only some potential sites can be developed. Offshore wind has a higher capacity and more consistent output than other variable RES, with the International Energy Agency describing it as a unique 'variable baseload' technology that could help to integrate the decarbonised energy systems of the future. A major constraint on offshore wind has been the difficulty of building fixed constructions in depths greater than 60 metres. Floating bases for offshore wind turbines could then prove to be a game changing technology, allowing much wider exploitation of wind resources. Many of the leading projects for commercialising these floating technologies are based in Europe. Hybrid projects linking offshore wind to other uses – such as hydrogen production or battery storage – represent another important avenue for offshore wind to contribute more widely to our energy systems. The Commission is expected to adopt a new strategy for offshore RES in 2020, proposing further EU action to scale up deployment of offshore wind and invest in its underlying technologies. Some EU Member States have set their own indicative targets for offshore wind deployment by 2030, accompanied by a range of support schemes. The European Parliament has been supportive of offshore wind energy, in particular the potential for a North Sea offshore grid (energy hub).
