Status and challenges for offshore wind energy

Worldwide demand for renewable energy is increasing rapidly because of the climate problem, and also because oil resources are limited. Wind energy appears as a clean and good solution to cope with a great part of this energy demand. As space is becoming scarce for the installation of onshore wind turbines, offshore wind energy becomes a good alternative. Renewable electricity from wind power can contribute to achieving Kyoto targets for sustainable energy development, but the green image of wind power may be jeopardized if wildlife is adversely affected. This paper deals with a brief revision of the status and development plans of offshore wind power, followed by a critical discussion about the existing challenges and attendant environmental impacts facing the offshore wind energy. Based on the discussions, suggestions are also recommended.
