Take into account that in some applications, you're not replacing like with like. Thermodynamic efficiencies mean that you need to have 2-3x less primary energy to get the same amount of final energy when your primary energy is already electric generation. The UK went from 2% to 42% electrical generation from renewable sources (not including nuclear) and almost half of that increase happened between 2015 and 2020. That's only electricity, of course, but a good chunk of transportation is going to come off of fossil fuels in the next 10 years as well. Most likely transitions will take a logistic curve, slow ramp-up, followed by a fast phase, followed by a slowing as the hardest problems are tackled.
