Even if wind turbines were built in Hawaii, excess capacity would have to be built to handle peak loads in the event that the winds weren’t blowing or the islands would experience brown-outs or black outs. The fact that the periods of highest demands would coincide with a drop off in wind speed means wind turbines cannot be counted on the meet peak load demands in Hawaii. So electrical generating capacity would have to be built twice, first as wind turbines and second as backup peak capacity protection.
