Connections I can make between Energy and Qi

Well, I know that I sometimes use those words interchangeably, depending on what I'm trying to express and to whom. As we are learning in TCM, everything has qi and as we know from science, everything has energy (or potential). In the body, energy outputs can be stronger at the points used for acupuncture and acupressure. Qi and blood flow together, when we are deficient in blood our energy is low. Energy moves, has currents, and a flow. Qi is movement, has channels, and flow. In my mind I guess that I don't have much of a distinction between energy and qi, so trying to point out connections feels redundant. Any statement I make about qi, I could use the word energy and the content of my statement would remain the same, and vice versa. I know that there are people who could and would argue with that, and, well, what can I say? People like to argue.
