For wind energy to be utilized; there must be a sufficient wind density to be able to move the heavy wind turbines and produce energy. (hubpages.com)
This means that regions with low wind densities will not be able to use the clean energy from the wind. (hubpages.com)
The islands boast consistently strong wind densities, great insolation characteristics, enormous reservoirs of geothermal energy, plant life that is perfect for the production of ethanol, and an incredible oceanic wave resource, all of which could be exploited by renewable technologies without damaging the environment.
