Chinese languages

Hello,

I am searching for the chinese sign for "energy". With this energy I mean the "internal energy" or "life energy". I have a proposal with three completely different signs:

Perhaps here is anybody who can help me in the concrete meaning of these three signs? It would be very nice!

Best wishes

To marco:
I try my best to give to a little help,my English is not good enought to make you understand well.
I'm sure you understand sometime you need to know the whole story for translate one word.I think in Chinese ,there are hard to find one word to fit both "internal energy" & "life energy".
energy can be 力 / 能量
life energy I'm quite sure it's "生命力" or "活力"
internal energy translate directly to be "內在能源"
