Offshore Wind
Worldwide
A total of 10 offshore projects are currently operational worldwide: the early projects were relatively small scale and shallow or sheltered waters. Not until Blyth Offshore came online, exposed as it is to the full force of the North Sea, could any be described as truly offshore. The newly-completed Horns Rev is the largest offshore project in the world.

Many other countries are also expressing serious intent in developing their offshore resource. Proposed projects include:
- Horns Rev II, Denmark, 200 MW + similar project, location to be decided.
- Mouth of the Western Scheldt River, Holland, 100 MW
- Ijmuiden, Holland, 100 MW
- Lillgrund Bank, Sweden, 48 MW
- Uttgrunden II, Sweden, 72 MW
- Barsebank, Sweden, 750 MW
- Kish Bank, Ireland 250 MW+
- Cape Wind, USA, 420 MW
- Long Island, USA, 140 MW
- Arklow II, Ireland, 500 MW
- Cape Trafalgar, Spain, 500 MW
- Thornton Bank, Belgium, 200 MW
There are also large projects in various stages of development in German Waters. Total planned projects are in excess of 30 GW. France also has 500 MW under consideration.
Utilising megawatt-plus class machines, these projects will generate higher volumes of electricity from the more constant wind regimes experienced at sea and are likely to play a major role in power generation in the future.
The EWEA have estimated that 5GW of the 60GW predicted for 2010 will be coming from the offshore sector.
