Energy is energy. One form of energy is not necessarily more "powerful" (word used in the common form) than another.
Power is energy per unit time.
Something which is more powerful either outputs or consumes a large amount of energy per unit time.
Energy can be used to do work. A powerful energy source can preform a relatively large amount of work in a relatively short period of time,
Saying that combustion is more or less powerful than other energy sources is not necessarily true. I would think that a small, smoldering, ember is less powerful than, say, an electric motor drawing a very high amount of current from the wall (at a high potential difference).
It would seem that you do not have a firm grasp of the terminology.

You are mixing up terminology here.
The amount of energy from a chemical process depends entirely on how much material you feed into the process.
Power is energy output per time interval.
Different forms of energy can be transformed into each other, usually with some loss as heat (unless heat energy is the desired outcome). Combustion produces first and foremost heat energy, with a bit of kinetic energy on the side as usually higher volumina of products are produced from low volumina of educts
If you want to produce kinetic energy from chemical energy, combustion is among the most wasteful processes. Especially when not in equilibrium. Electrical energy transforms better into kinetic energy.
Nuclear processes currently only produce heat that has to be transformed into kinetic or electrical energy. The specific energy (per gram, or whatever mass unit you prefer) is a lot higher than chemical energy. As with all heat engines, you need a cooling environment to gain any kinetic or electrical energy, and the amount of energy you can gain is dependent on the temperature difference.
Using evaporation (steam engines) doesn't really beat carnot engines, but seems to be easier to build.

Yes, the energy in a combustion process is an energy released by weak energy (The order of strength goes Gravity, Weak energy, Magnetic energy, Strong Energy). Strong energy is best seen in the breaking apart of an atom, as in the reaction that happens in a nuclear bomb. The breaking apart of a bond that uses strong energy e.g. the electron to the nucleus of the atom, releases what whe know to be the most powerful form of energy.

solar?
fission
fusion
matter/antimatter
Vaccum energy???
Also, hydrocarbon combustion is not the only form of combustion.
I don't know the hierarchy of combustion energenics...

Nuclear fission and fusion come to mind.
