Wind energy is currently the fastest growing renewable energy sector globally, with an average growth rate of 25% per year for the past 10 years. In this newsletter we provided an overview of some important technical developments and challenges that the industry faces. We focus a key area relating to materials technology, namely blade materials and manufacturing, but also turbine technology. As reported in our newsletters on aerospace, the wind power industry is benefiting from materials and manufacturing technology relating to carbon fiber composites.
