The hidden consequences of a massive use of intermittent renewable energy systems for electricity production are highlighted, using existing electricity production data from Germany from the last 5 years, where presently a system is in operation with an installed capacity of about 50 GW in wind turbines (sum of onshore and offshore wind) and 40GW in photovoltaic panels.This fleet of intermittent renewable systems produces more than half of the yearly renewable electrical energy of Germany, the rest being produced by hydro, so-called ‘biomass’ and a very small fraction of geothermal sources
