A good example would be the Portland Alcoa smelter. They were trying to find a power supply new contract due to the French owned Hazelwood power station being shut down. Then one of the two power supplies was down for maintenance during the rough weather recently and they had to rely on the renewable SA inter-grid system and then it all went out as well, which isn't surprising as it went down a few months ago!
I was talking to one of the workers from Alcoa a few weeks ago who said that it would be easier to close the whole plant as the cost to remove or fix the pot line would be too costly. He said he can guarantee it will be closed soon.
I guess its another job for China while the government complain about unemployment. It'll turn Portland into a ghost town thats for sure.
