The other thing the current oil crisis has brought home to me is the extent to which we still rely on oil. A depressing article in the Globe and Mail entitled "What energy transition? The Middle East war shows the world still runs on oil", pointed out that 87% of total global energy in the 1970s was from fossil fuels (oil, gas and coal), and that figure today is still 81%.
And that does seem to be the case: the Energy Institute's 2024 Statistical Review of World Energy shows that primary energy consumption is filled 31.7% by oil, 26.5% by coal, 23.3% by natural gas (so, 81.5% by fossil fuels in total), 4.0% by nuclear, 6.4% by hydroelectricity, and 8.2% by other renewables (mainly wind and solar). So, 18.6% could be called carbon-free. Furthermore, overall energy consumption is still increasing at a pretty steady clip.
