In what would be a really unusual irony the hydropower would definitely be “green” but it is making Greenland environmentalists queasy since it is exploiting a problem that Alcoa and other aluminum companies have helped exacerbate.
Already, according to reports, oil companies are drilling for oil and gas in the Arctic off the west coast of Greenland and mining companies have explored deposits of lead and zinc from rock that has been buried under the melting glaciers for eons.
It is unclear just how the new frontier of aluminum smelting would impact the same industry in the US since most of the electricity required here depends on coal. Currently the Tri-state region surrounding Evansville is home of three giant aluminum smelters.
Alcoa Warrick Operations is the largest smelter in the US.
