Most furnaces burn some kind of fuel. The fuel (wood, oil, coal, etc) contains chemical energy bound up in its molecular structure. Oxygen from the air is combined with the fuel and breaks old chemical bonds to form new chemical bonds with less energy. The extra energy is released as heat and light.

"Octanol is not the most energy efficient fuel. Butanol is. Octanol gives out 8691.34J of energy per gram. Butanol gives out 15521.21J of energy per gram" Please state your source.

using 10 kg of fuel in a fuel cell.

The bottom of the pyramid contains the most energy.
The question makes no sense - you can't consider two variables at once - energy and mass. Most energy for the same mass - hydrogen.
A match. Solid rocket fuel.
Rocket fuels are used. It contains chemical energy

UV-A contains the least radiation (or energy) and is therefore, the least harmful. UV-C contains the most amount of energy and is the most harmful.
A fuel such as coal or oil contains what might be called 'potential chemical energy'. The potential energy will remain there until the fuel is ignited and then the reaction with oxygen in the atmosphere starts, we call that 'burning'. So if you don't burn the fuel the potential energy just stays there.
Fossil fuels contain chemical potential energy, which is released as thermal energy when they burn. Nuclear fuel which can undergo fission contains energy by virtue of the change of mass which occurs when the nucleus is split into fragments, initially this is released as kinetic energy which is absorbed in the fuel and released as thermal energy.

Adenosine Tri-phospate or ATP is the molecule that contains the most energy.
