Geoff asks:

"If all energy can't be destroyed but only transformed, where does it original come from?"

What do you think?

I think that the energy locked up in matter equates with the negative energy of gravity so that they add up to zero.

According to current theories, all the energy in the universe was present at the Big Bang.
- Baryonic matter was mostly Hydrogen, with some Helium
- The energy we use today came mostly from turning hydrogen into heavier elements in stars, plus gravity
- Uranium for fission comes from the end stage of this process, when neutron stars collide

all energy can't be destroyed but only transformed

However, an equally important factor is entropy, and it can't be created, but only degraded (in a closed system).

The Big Bang provided a low-entropy start to the universe, and entropy has been inexorably increasing since then.

Energy is the mathematical concept used to model how the universe works. It comes in a variety of forms. The fact that energy is conserved can be initially derived from  Newton's laws of motion and inertia. Add in quantum mechanics and general relativity and you have a comprehensive way of modeling the world and the whole universe.

Studying the forms of energy and potential energy is a fascinating subject with some tough concepts underpinning it. Worth the effort in my opinion.

If energy is a coin of exchange then it should belong to transformations as it seems to me? If you're thinking of 'pure energy' then ?? A quark gluon plasma as just after a Big Bang? Temperature?

I would guess 'light' is the closest to it, presuming something able to 'pressure' it. At least if you go by the Big Bang.
Or just 'forces'

Actually I don't know. It's like asking how the universe came to be, was it 'laws' that was its origin, or 'forces'. Or are they the same?
