Sacrifice To Power Spells Options

I'm wondering if anyone could explain to me a little more of the theory behind a sacrifice of some sort (not necessarily living, mind you) powering or empowering a working. I've encountered the concept a lot, but sacrifice as I understood it involved giving something to (the) god(s); can its energy be harnessed? Indeed, is there energy to harness?

Any and all thoughts welcome. (IMG:style_emoticons/default/smile.gif)

In physics, we create a lower entropy subsystem (in say, drawing a circle) by increasing the entropy of the overall system. One could say that sacrifices are analogous to creating the possibility to create your entropic reversion effects (magick) by creating the reaction (increase of overall System entropy) first. Of course sacrifice is only one method.
