Meeting the demand for human resources of a growing US wind industry was a major focus of this year's American wind industry convention in Houston. A job fair ran daily in the exhibition hall, along with a half-day seminar on careers in wind as part of the educational session. Getting enough people to fill available jobs in the industry is becoming a major preoccupation. "At Clipper, we see that right behind the supply chain constraints is the people challenge," said the company's Robert Gates. FPL's Mike O'Sullivan says the situation is the same for other parts of the energy industry as well. "As the wind business has exploded in the US in the last few years, getting the human talent and the human capital to develop, operate, staff, deploy, maintain -- whatever part of the food chain you are involved in -- is probably the biggest challenge many of us have. In the short to medium term I don't see that going away."
