Hurricanes are driven by temperature differences over huge expanses of the ocean; not only is the area large but the total energy in the equation is massive. A category 5 hurricane has an energy conversion rate of around "600 billion kilowatts, equal to about 200 times the world's electrical generating capacity, or 10 Hiroshima-size bombs exploding every second."

Basically, we don't have the power much less the ability to properly apply it. A better application of effort would be to start building things above sea level.
