The portable crane operator stares intently at two co-workers on the ground below. Communication between them is all-important. Place a 44-metre, seven-tonne wind turbine blade too far to one side and the flatbed truck could tip over. Drop it too quickly and the blade — or the crew — could be seriously damaged.
This scene — on a clear autumn day at a Vestas plant in Windsor, Colorado — seems like a metaphor for the entire US wind industry.
