Wind energy supply has grown rapidly over the last decade. However, the long-term contribution of wind to future energy supply, and the degree to which policy support is necessary to motivate higher levels of deployment, depends—in part—on the future costs of both onshore and offshore wind. In this study we summarize the results of an expert survey of 163 of the world’s foremost wind experts, aimed at better understanding future costs and technology advancement possibilities. Three wind applications were covered: onshore (land-based) wind, fixed-bottom offshore wind, and floating offshore wind. Results are summarized in the “infographic” below.
Overall, results suggest significant opportunities for cost reductions, but also underlying uncertainties:
Overall, insights gained through the expert survey complement other tools for evaluating cost reduction potential, and can help inform policy and planning, R&D, and industry strategy.
