The world needs a new source of energy, an unspillable source.

is the electricity generated from wind turbines dependent on wind speed and swept area alone?

or is it that the faster the rpm, the more the production. (of course this in itself is dependent on the above two criteria) what i need to know is whether a alternator produces same energy at 100 rpm and 300 rpm. also what are the factors that decide how much energy a alternator produces.
