Things that drain

Things like the sun make people happy but it drains so much energy. A fire on a winter's eve takes energy. Dancing in the rain takes energy. A day out with good friends take energy. So I remember some law I learnt in physics 'energy can not be made or destroyed it can only be moved from one form to another' So where does that energy go? I'm thinking it makes memories or gives you that happy feeling. It's not the warm and fuzzy type[feeling fuzzy isn't too good in my books] It's just indescribable in a descriptive way. If that makes any sense.
