The term "energy" is actually used in a variety of contexts, such as heat energy of a beaker of liquid, or radiation energy of infrared light, or kinetic energy of a speeding bullet, or even "mass-energy" of warped relativistic spacetime. But you want something "pure", not associated with any matter or particles (yes, even light is particles of photons). Well, we've got potential energy, which is an abstraction, not necessarily itself composed of particles or waves, even though it does require the presence of such. An object placed at a higher altitude, for example, is said to have "higher potential energy", meaning that it took work to get it up there, and when allowed to fall, will do work, or give up energy. As trivial this may sound, it actually plays a fundamental role in many general equations in classical, relativistic, and quantum physics. This is one kind of abstraction of energy that cannot really be "put into a bottle", nor can it be seen or even detected with instruments. Funny, huh? More than anything else, it's really just a computatational place-keeper rather than something real that you find in nature. No physicist has ever said, "Hey, there goes a bit of potential energy, whizzing by!"

Hah! Your question is a philosophical one. you need to basically as quite ask "what's organic organic organic reality?" Wait a minute besides the undeniable fact that. IS 'power' authentic? I argue it isn't. The keyboard i'm typing on is authentic. Are keyboards authentic? No. "keyboards" are an abstraction; they seem to be a type that we outline. The keyboard i'm typing on I grow to be conscious of as a keyboard (I call it) yet i'm no longer defining it. it is particular. it is authentic. reality is what the Universe is, it is one aspect. We destroy down elements of it, we crew elements mutually and create precis issues we call diverse kinds. We make a mistake when we assume of of a type as "authentic". Its contributors will be (a number of them) authentic, besides the undeniable fact that the category itself is arbitrary. Is a contact pad a member of the category "keyboard"? See how arbitrary diverse kinds are? power is a sources of elements of reality it is functional to us because it has patience. We hence are waiting to "use" the concept to finish objectives. yet, and the following is my argument, power is a type so does no longer exist as a separate "aspect". it isn't authentic. it is a type. that can help you get your suggestions round this, imagine about entropy. Entropy is basically as authentic as power. it is way less accepted to us, so we are more beneficial smooth in wondering about it as an precis sources which will enhance with time in any remoted equipment. besides the undeniable fact that it is one of those particular situations describing area of the universe. Deep sh_t. whats up, it is yet another one: Are numbers authentic? if so, educate me one! and do not make the mistakes for claiming an emblem or a mark on slightly of paper is a spread. reality is a solidarity which we dissect and/or decompose into issues we may be able to discuss yet those issues are short and fail to wisely BE the reality. the completed is larger than the sum of the elements. placed it yet in a unique way: power is the (scalar) cost of the momentum vector's time coordinate of an adventure in 4°D spacetime.

there is nothing like pure energy.
Energy just has various forms
