Although wind energy is a rapidly growing technology its use remains geographically concentrated, with more than 75 percent
of global installed capacity found in just five countries. These countries, and others wishing to develop wind energy have
implemented various supportive policies covering areas as diverse as tariffs, technical R&D, administrative procedures, or education and communication, and range from direct project subsidies to general awareness raising. Experience shows that good wind resources are not on their own sufficient to ensure strong wind energy development and reductions of the cost of wind
energy.
