That's complete crap. All it takes is a reasonable investment in technologies like wind and solar. For example, I'm in Australia. Aluminium smelting here consumes about 1/3 of the electrical energy produced. Mostly that's done with hugely subsidised brown coal. If there were a serious effort to use solar power to smelt Aluminium instead, you'd see a big reduction in the CO2 produced, and it'd likely be cheaper than the current situation. But there isn't the political will to get it done - primarily because of idiotic arguments like yours.
