If only it was only squared, it's actually cubed, twice the speed = eight times the power
way i think of it is getting hit by a cube of air on a conveyor belt, at twice the speed that cube has v^2 the energy
but at twice the speed, more (two in this example) of those cubes of air can hit you in the same time (power is energy / time) as one did previously, so the power is cubed
