The growth in wind-based electric power generation can be in large part attributed to its competitive cost of energy in comparison to fossil-fuel energy sources with none of the cost volatility associated. Modern utility scale wind power started with relatively small and expensive turbines in the 1980s; since then,wind turbines have increased markedly in size and the cost of energy has dramatically decreased. The larger turbines benefit from increased wind power capture through a much larger rotor and from increased wind speeds at the higher hub height. However, the benefits of larger diameter rotors potentially come with increasing turbine cost and, hence, cost of energy. To keep cost of energy down, mass and stress increases must be carefully managed as rotor diameters grow. Technologies allowing wind turbine rotors to achieve higher performance to mass ratios are the focus of this presentation.
