Fair enough, though gas imports from Russia have their environmental and human impact, too (up to and including a war in Ukraine, as the country is an inconvenient obstacle for cheap overland pipelines if it is not under Russian control in the way it was with Yanukovych).

BTW I find it somewhat scandalous that Russian gas companies can hire senior politicians (such as former German chancellor Gerhard Schröder and Finnish prime minister Paavo Lipponen) to assist the political approvals. Although these men are no longer in such official positions, it is obvious that they were given money to advance the interests of Северный поток through their connections in their respective social democratic parties.
