Non-Solar Sustainable Energy: Wind

Wind energy research began in the 1970s, with NASA’s analytical model to predict the power generated by wind turbines. Currently, Sandia National Laboratories and National Renewable Energy Laboratory have programs dedicated to wind research. Sandia’s laboratory focuses on the advancement of materials, while the NREL wind projects are centered around making wind energy more cost effective. The president of Sky WindPower Corporation predicts wind turbines will eventually generate electricity at $0.01/kWh, a fraction of the cost of coal. Today, 3.1% of electricity globally is harnessed from the wind.

Wind power shows that solar energy is but one of multiple valid options in the realm of sustainable energy.
