If it is burned - which is the way such fuels are usually used -
the energy efficiency is the energy efficiency of a heat engine.
The theoretical maximum efficiency is the Carnot efficiency; the
real efficiency will usually be considerably less than that.

Photosynthesis is when the plants get minerals from the sun, to
make plant food, the sun is the energy which is then turned to
