Alternative Energy Wind, Solar, Hydro and other alt

Five Miamis may not seem significant, but if we make the predicted strides in the near future, wind power could be one of our main sources of electricity. Though wind energy is now more affordable, more available, and pollutionfree, it does have some drawbacks. Wind power suffers from the same lack of energy density as direct solar radiation.
