The U.S. Department if Energy (DOE) estimates that by 2030, wind power could potentiallly displace between 3 and 4 quadrillion (10 15) Btus (quads) of primary energy, with an installed electrical generation capacity of 120.000 to 160.000 MW. This forecast is based upon economic analyses indicating that the costs of wind-generated electricity could be cost competitive with conventional fossil-fuel-based generation by early next century. The key to realizing this objective is overcoming technical challenges to the development of a next-generation of advanced wind turbines. These challenges include the detailed characterization of wind inflow to turbines at wind-power-plant sites, an understanding of unsteady aerodynamics, the development of sophisticated computer models of all aspects of turbine operation, and the application of a better understanding of component and system fatigue to new designs. Advanced wind systems will include such new technologies as blade designs incorporating advanced airfoils and new materials, variable speed operation, advanced power electronics, rotor-hub enhancements, tall towers, aerodynamic controls, advanced drive trains, and expert control systems. A larger market share for wind energy will also require the resolution of issues surrounding transmission, storage, and the integration of an intermittent energy source into the utility grid.
