Most road vehicles are currently powered by gasoline and diesel, both of which come from refining crude oil. Other industrial processes are also powered by diesel. How does all this look in terms of [[energy]] units?

Note: in the the equations, the <code>(gasoline/oil)</code> and <code>(toe/tonne)</code> are there to convert the fuel mass into energy units, using some of the [[calculator]]'s built-in units.

How does this compare to the supply of [[biomass waste]]? Rough estimate:
{{dp
|crop_residues
|1.7 billion tonnes/year
|Dry mass of all crop residues, byproducts, and oilseed cakes except for soybean
|This should be, in principle, all human-inedible parts of food crops (inedible due to being too fibrous, whereas ruminants can digest the fiber and get calories from it). Soybean meal is not counted, because it can be turned into human food (soy flour).

* crop residues would be less if fewer crops were grown in the first place
** i.e. if we [[food waste|wasted less food]]
** i.e. if we fed fewer crops to chickens, pigs, etc
* crop residues have other competing demand
** [[packaging]]
** food for ruminants (cows)
** base for cultivating [[mushrooms]]
* there may be other biomass waste besides crop residues
** sawdust
