Offshore Wind Power Market Share, Statistics | Global

Market SegmentationRegional AnalysisKey Market DriversReport CoverageKey Industry Developments"Fixed Offshore Structure Segment to Dominate the Market by Installation" Countries around the world are focusing on increasing investment in offshore wind power projects to extract energy from natural wind resources available in the environment, thereby fueling the global market. Installing offshore wind power is a challenging task because it requires movement of heavy and big equipment to the project location which increases the overall cost per kW. But with the introduction of advanced technology and cost-effective solutions for offshore installation & wind turbines, the overall cost has become lower than earlier which makes the offshore wind a feasible option among the renewable energy category. In terms of installation type, the most preferred technology for offshore wind power is the fixed structure due to the ease of operation and cost-effectiveness. Currently, the fixed structure segment dominates the global offshore wind power market share with floating structure is at a ve...Get price
