Climber Tassos Baltas points up at a 22-meter high mast which is monitoring wind speeds on the summit of a rocky hillside on the Greek island of Evia and declares, "This mast which has been installed next to us is an omen of catastrophe."

They are running into local opposition, bureaucratic red tape and legal tangles in the permitting process — to the point where the EU is veering off track for its emissions-cutting goals, wind industry data shows.
