Wind energy is now an established means of alternative energy generation. Wind energy farms are a regular feature of the landscape in many countries, and large off shore wind turbine farms are being raised in many places as well. However, the hunt for more efficient means of wind energy generation continues. The seminar focuses on the challenges for Physics and Engineering surrounding materials technology, tribology and mechanical sciences. A principal factor in increasing efficiency is blade length, blade design and appropriate material selection. In addition, the mechanics of the drive trains and energy conversion systems play a key role in the efficiency of the wind power plant. In the move to the offshore environment, maintenance becomes a driving factor along with corrosion and other features associated with surfaces. The seminar aims to identify the key challenges for future development and target areas for future research and development investment.
