Renewable energy stocks are outperforming fossil fuel companies during the energy crisis triggered by the war in Iran, reshaping investor sentiment as both sectors post gains but clean energy leads in relative performance.Since the crisis began, German wind turbine manufacturer Nordex has surged 71%. Littelfuse, which produces sensors used in electric vehicles, rose 61%. Elia, which expands electricity grids in Belgium and Germany, gained 26%. In Denmark, Orsted increased 40%. Elmos, a German supplier of chips for electric vehicles, has nearly doubled in value this year.
