Aluminium smelters in Germany are actually getting a big subsidy. They&#x27;re varying their electricity usage based upon the output of Germany&#x27;s solar&#x2F;wind farms and getting paid a hefty sum to do so (possibly too much).<p>This is having a negative impact on other smelters across the world.<p>Effectively they&#x27;re doing the same job we were always told batteries would do.
