Taiwan has advantages in the development of offshore wind power, as it has abundant wind energy resources at the seas. The local government has developed a series of measures to promote the development of wind power generation industry. The development of offshore wind farm in Taiwan, however, has to solve the problems that offshore wind farms are overlapping with some traditional fishing grounds and are unable to reach consensus with relevant stakeholders. This paper starts from the great potential of offshore wind power in Taiwan and the active promotion of the government, and analyses the impact and possible opportunities brought by offshore wind farm development to local fisheries, from the perspective of Zhanghua Area, a key area of development of offshore wind farm in Taiwan. This paper proposes that the local government in Taiwan should use marine spatial planning as a tool, through the comprehensive participation of government, developers, fishermen and other bodies, seeking the coexistence and prosperity of offshore wind farm and fisheries. Avoidance, compensation, and feedback, as well as communication and collaboration will be an important strategy to solve the conflicts of multiple use of the sea and to promote the development of marine renewable energy.
