It seems impossible in an isolated 1v1 lane. As a melee, if you go in on him, he stuns you point blank then chases with E and gets autos off. if you farm passively then you still get harassed and lose a ton of CS. Even with a jungler gank, unless they get a good lockdown with Vi, Xin or any other high CC gank jungler, he just E's away. I know I'm playing wrong though, because Kennen isn't 100% win rate.
