Achieving 20% wind energy will require the number of turbine installations to increase from approximately 2000 per year in 2006 to almost 7000 per year in 2017.
Integrating 20% wind energy into the grid can be done reliably for less than 0.5 cents per kWh.Achieving 20% wind energy is not limited by the availability of raw materials.Addressing transmission challenges such as siting and cost allocation of new transmission lines to access the nation's best wind resources will be required to achieve 20% wind energy.
