Mr Kaeser highlighted the challenging reality of transformation costs, urging acceptance of higher pricing by consumers.
In an interview with The Telegraph, the boss of Britain’s biggest wind turbine manufacturer said: “Every transformation comes at a cost and every transformation is painful. And that’s something which the energy industry and the public sector – governments – don’t really want to hear.
“I believe that for a while (customers) need to accept higher pricing. And then there might be innovation – about the weight of the blades, other efficiency methods, technology – so the cost can then go down again. But the point is, if there is no profit pool in an industry, why should that industry innovate?”
