世界の洋上風力発電の将来

Recent environmental awareness resulting particularly from the phenomenon of global warming has pushed renewable sources of energy towards the top of the power generation agenda. This has helped promote wind power as the most cost effective of the renewable technologies.

The Future of Global Wind Power: the technology, economics and impact of wind power generation is a management report that analyses the prospects for offshore wind power generation across Europe, North America, Japan and the rest of the world. It provides key data on the trends in wind power generation, to help you predict where and when opportunities in offshore wind power generation will occur.

The report explains how to identify potential sites and use advances in technology ensure the most effective use of resources. It also details the environmental costs and benefits of offshore wind farms with reference to key stakeholders. These impacts are examined with reference to national, European and International regulatory frameworks. Forecasts to 2020 are included in respect of future capacity and changes in costs resulting from scale and technological advances.
