What Was the Initial Energy of the Universe: Planck Energy or Singularity?

[liometopum]

I am wondering what people here think the initial energy of the universe was.

The Planck energy? Implies a finite amount of energy
A Singularity? This implies an infinite amount of energy.

Zero? Implies that Lawrence Krauss is right.(:P)

Thanks Bandersnatch. I'd thought of listing that too, but it was my impression that at the moment the expansion started that at least a little something was there. My post was purposely vague though and left that idea fully available.
The initial singularity is often described as being of infinite energy and matter: http://en.wikipedia.org/wiki/Initial_singularity
Infinite is infinite... it would not be a universe from nothing, if there was a singularity of infinite energy at the moment expansion started; all the energy is already there. I have heard lecturers state the universe started with a small amount of energy, quite contrary to an infinite amount. With two extremes, I wanted to hear input from forum members.
I guess I should define the starting condition I am thinking of, and that is the start of expansion.

Actually, there isn't an unambiguous answer to this question: global energy is not a well-defined quantity in General Relativity. Either way, the answer is probably somewhere between small and zero, depending upon how you define the global energy.
