I think you'd have to explain what you mean by 'types of energy' first.
The different types of energy that are mentioned on Wikipedia are:
Mechanical (kinetic, surface, elastic potential and sound)
Gravitational
Thermal
Electric (electrostatic, electricity, magnetic and electromagnetic (light and other radiation)
Chemical
Nuclear
I have to say that chemical energy is the one that is the most used today, since all living things digest food, cars use gasoline, coal is/was used to "produce" electricity, etc.
EDIT: Is this a continuation of the superhero question? If so, then the form of energy most useful as a superpower is probably...electric! Just because you can control light and lightning.
