The claim is strongly supported by the official UN Secretary-General statement, 'Secretary-General's video message to the Petersberg Climate Dialogue,' which says 'the conflict in the Middle East has triggered the most severe energy crisis in a generation.' The official UN DESA page, 'Guterres urges countries to ‘unleash the renewables revolution’,' corroborates both elements: the energy-crisis warning and Guterres' criticism of fossil-fuel dependence, stating fossil fuels 'hold economies hostage.' The wording 'worst energy crisis in decades' is a close paraphrase of 'most severe energy crisis in a generation,' so the claim is substantively accurate.
