E.ON chief executive Johannes Teyssen spoke out against an unfettered build-out of onshore turbine capacity in Germany, as he responded to questions about how much expansion of wind and solar the country’s population will accept.

“I believe, it can’t go on like that,” Teyssen told an audience of several hundred energy industry officials and executives on Tuesday at the Energy Industry 2018 conference in Berlin organised by German financial daily Handelsblatt.
