[Greenbuilding] Energy Numbers

[Reuben Deumling]

This comparison I didn't understand:

Explosion of 1 kg of TNT 10e6 Joules
Woman running for 1 hr  10e6 Joules
Candy bar                       10e6 Joules

I'd like to know a little more about how these numbers are calculated.
Presumably in the case of TNT it is energy released; in the case of the
woman it is expended, but in the case of the candy bar I'm not sure -
contained in the nuts and sucrose? Seems kind of gimmicky.
