True. I’m an electrical engineer working in renewable energy. I live off grid on solar and tank water. No oil means no car tyres, no plastics, no car seats, no industry. No electric cars. No nuclear power stations, no electronics, no internet. Back to how things were before the Industrial Revolution, but without coal mining. No coal means no steel, no aluminium. No diesel means no modern agriculture, no mining at all, and no construction industry. No “fossil” fuels means no modern civilisation. Then the only way to live is like the Amish. Pretty good way to live, but only a small population could survive. Next to nobody in cold climates without coal. The green dream is another name for depopulation, genocide. Ask a veterinarian what a green dream is. (My sister is a vet, the lethal injection for animals is coloured green.)
