Stated numerous times as being unique? Or maybe just unknown. Prior to Hal it was deemed magical.. then later almost tech based...
The energy you speak of was (as far as I'm concerned) defined or even retconned if you like, during the kyle rayner era in order to separate the science of the green lantern rings from the magical green flame and starheart that Alan Scott uses.
And btw. if its so unique... how would the tech based weaponer have created sinestro's yellow ring that the others are based on...
And when has Mongul faced off against someone that was trying to drain him, and willed it to stop.
