The climate change fanatics, apart from attacking meat, and wanting us to eat bugs, but probably to just die, push for green energy, renewables. These are sacred things to them, part of the new Garden of Eden in their theology. The transition to the renewable world is supposed to take place by 2050. However, as detailed below, not only are there insufficient rare earths to rebuild our entire society, but the transition is going to be enormously polluting in terms of carbon production. Not only must the traditional structures be reconstructed, but the new renewable source will need to be made, and here is a carbon footprint in making solar panels. Not only that but there are no cost-effective substitutes for all the goods from plastics to chemicals, that use hydrocarbons.
While the evidence shows the impossibility of sustaining modern civilisation in the Green framework, and while they are not explicit about this, most Greens would like to see a collapse of the West and all it represents in typical nihilist Left fashion.
