Hans Bünting is chief executive of RWE Innogy, the renewables arm of German utility RWE, which has been struggling financially in recent years due to its overreliance on loss-making fossil-fuel plants. Renewables are one of the company's three core growth areas, with €1bn ($1.07bn) due to be invested in green energy over the next three years.

RWE Innogy is involved in two huge UK North Sea offshore wind projects.
