The use of FRP materials in wind turbines is an important technical element. Components must exhibit excellent fatigue strength, resist random loading and corrosion, require minimal maintenance and serve for 30+ years. Uncertainties over the performance of initial experiments with steel and aluminium have been overcome with the use of composite members, on which production is now almost entirely based. The blades are the main components, and the performance of the turbine is ultimately dictated by their efficiency. The use of lighter weight FRP materials means that the turbines can produce more power per unit volume, minimising impact on the landscape.

There is mixed public opinion over the introduction of large wind 'farms', the main concerns being over visual intrusion. However, it is envisaged that the potential economic savings, along with substantial environmental benefits will dispel these concerns. There are numerous examples of wind farms worldwide that are now in public favour.

Offshore wind farms are a recent, high impact development. FRP materials will be instrumental in the success of offshore programmes due to their proven performance in corrosive and hostile environments, which will maintain efficiency of the structures under increased locational costs.

As materials and manufacturing processes develop rapidly, making turbines cheaper and more efficient, the cost of electricity they produce will be continually reduced.
