Exactly where is all that energy coming from to charge those electric cars? How much energy does it take to produce those batteries & how toxic are they when they need to be replaced?  How much petroleum goes into the plastics in a solar panel? How much metal/ore/mining (which uses coal to produce enough heat to smelt metals and diesel to power equipment to mine it) goes into producing wires in those windmills & solar panels? And don't get me started on the migratory birds & raptors that are being killed by windmills and heat reflection from solar panels. Look it all up & do your own research before slipping into fantasy land.
