There is well known authority for the simple, concrete, scientific definition of energy. Take Einstein's equation, E=mc2, that every schoolchild knows but so few spend the 30 seconds it takes to understand. Energy equals mass times the speed of light squared. Speed is a function of distance and time, so energy can be expressed in mass, distance, and time. That's how we define work that can be done: actual, physical work. Energy is a measurement of work. If I lift a rock, I'm inputting enough potential energy to dent the surface of the table one centimeter when I drop it. The calories of chemical potential energy that my bloodstream absorbs when I eat a Power Bar charge up my muscles enough to dig 100kg of dirt in my garden. Nowhere did Einstein discuss hovering glowing clouds, or fields of mystical power generated by human spirits.
When spiritualists discuss energy, don't blindly accept what they're saying simply because energy is a word you're familiar with, and that sounds scientific. In many cases, their usage of the word is meaningless. When you hear the word energy casually used to explain a mystical force or capability, require clarification. Require that the energy be defined. Is it heat? Is it a spinning flywheel?
Here's a good test. When you hear the word energy used in a spiritual or paranormal sense, substitute the phrase "measurable work capability." Does the usage still make sense? Are you actually being given any information that supports the claim being made? Remember, energy itself is not the thing being measured: energy is the measurement of work performed or of potential.
