Steel and coal, a classic pairing. Along with the battle of tariffs on steel, Donald Trump is pursuing the revival of coal, whose mines are located in some American states that voted for him hoping for the rebirth of the mines. Will Trump keep his promises? It seems so, and to say it (numbers in hand) is not some analyst his supporter, but the Rainforest Action Network, an environmental group for which these developments are like smoke in the eyes : in a report lets the world know that coal with Trump is experiencing a second youth and that financial flows to this sector in America have exploded from almost zero in 2016 to one and a half billion dollars in 2017. A novelty that cannot be ignored.
