UTRECHT – Under the motto necessity or madness, supporters and opponents crossed swords on Saturday about the usefulness and necessity of installing windmills in Utrecht. The debate in the run-up to the municipal elections was organized by Buren van Rijnenburg and Buren van Lage Weide, in collaboration with the Stadspodium. City councilors and scientists also took part in the discussion in Zimihc in Overvecht. The windmill debate is here to see again.
