Three links worth to read in German: profile at Greenpeace where Aloys Wobben expresses his opinion that unions are the main culprit for the downfall of midsize enterprises(...), taz article with examples of union-busting at Enercon (the end of that article claims, without naming names, that other eco-technology leaders think Enercon's practices are damaging the reputation of the whole industry), and another taz article about the firing of 70 employees in Turkey for joining a union (a decision of the local manager the company headquarters refused to comment).

Just because a company is not listed doesn't mean it's not a real company, I'd rather call it ideal. Strong long term owners, often the founding family, is a recipe for success in the long term and an antidote to quarter capitalism. See Enercon, Bechtel, Cargill, IKEA, Bosch, Tetra Laval and so on.

Peak oil is not an energy crisis. It is a liquid fuel crisis.
