A transition slows with the size of what it replaces
The claim
An energy transition runs slower the larger the system it has to displace: new renewables grew about 50-fold from 2000 to 2020, yet fossil carbon's share of world primary energy fell only from 87% to 85%, because total demand is an order of magnitude larger than when coal displaced wood.
Argument role: rate of change. Ch. 7 chunks 532-534. The share barely moved because growth in the new source was measured against a denominator that kept growing; most of the 2-point drop Smil attributes to hydro, an old renewable. Number check: the 87% start is confirmed independently in The Coming Wave (87% to 84% since 2000, chunk 205). Application: any abundance claim that cites growth multiples of a new source should also state its share of the total, because the share is what sets the timeline.

groundsSource document
Even though the supply of new renewables – wind, solar, and new biofuels – rose impressively – about 50-fold during the first 20 years of the 21st century – the world's dependence on fossil carbon declined only marginally, from 87% to 85% of the total supply
groundsSource document
even a tripling or quadrupling of the recent pace of decarbonization would still leave fossil carbon dominant by 2050.
