Me and most relatives were exposed to this propaganda in school during the 80s and 90s.we produced more clean energy from nuclear power plants than we do now from solar and wind, if you measure actual power generation and not theoretical capacity. The only "cloud" to speak of today is the neverending plume of fine dust particles and carcinogens from the still operational coal plants that we require as backup for our maddeningly expensive bet on intermittent energy.
