The sheer amount of water needed to create some kinds of alternative energy could suck certain regions dry, upping the odds of resource-based conflict. And as the world builds scores more emissions-free nuclear power plants, the risk that terrorists get their hands on dangerous atomic materials — or that states launch nuclear-weapons programs — goes up.
