So if 'pure energy' doesnt exist could you tell me where all this energy thats around us came from? also is there energy lying dormant around us that isnt being used or transfered? and how does the transformation take place? I know this is alot of questions im quite annoying sometimes

Im a bit new to this and ive been asking this question to a few people but I havent had an answer yet. Can any one help? Im asking if any one can give me a definition for pure energy? Does it even exist? Thanks
