Am I dense, or is it actually showing how much total global CO2 mitigation we can expect from each sector? I.e., it shows we expect countries to build much more renewables than nuclear until 2030, which may be a good choice for them, but that doesn't mean renewables are 10x more efficient. (If Tesla Model X sells 10x as many as Hyundai Ioniq 6, that doesn't mean Model X is 10x as efficient.)
