A new study by the Carnegie Institute and the Lawrence Livermore National Laboratory has discovered that wind power could easily meet the entire planets energy needs.
They study determined to find the geophysical limits of wind power, how much is physically possible before the turbines use up all wind energy in the world. They used computer models to calculate the amount of power that could be generated by wind energy at low altitude (land-based, and offshore turbines) and high altitude (upper atmosphere turbines using kite technology), and also the potential impacts on the climate.
“Turbines create drag, or resistance, which removes momentum from the winds and tends to slow them. As the number of wind turbines increase, the amount of energy that is extracted increases. But at some point, the winds would be slowed so much that adding more turbines will not generate more electricity. This study focused on finding the point at which energy extraction is highest.”
“Using models, the team was able to determine that more than 400 terrawatts of power could be extracted from surface winds and more than 1,800 terrawatts could be generated by winds extracted throughout the atmosphere.”
The current global demand is 18 TW of power.
