This is a brilliant video. Renewables, which are near-100% efficient, don’t need to replace all of the energy fossil fuels produce. They only need to replace 20-30% of that energy. Fossil fuel technologies are so hopelessly inefficient (‘rubbish’ as I often call them, because they really are), that 70-80% of the energy they burn is never used. It’s lost as heat and pollution.
