I think "enthusiasm" is more descriptive than "energy". I typically enjoy interviews since I'm a depth-first learner as opposed to breadth first, and interviews are an opportunity to talk about all kinds of things I've learned. Depth first learning meaning that I go deep a specific topic before learning adjacent topics (e.g. if building a database access layer + cache, I'll go deep on Redis documentation, which cause me to go deep on specific redis commands, etc. then after redis I move on to cache rehydration strategies, etc). This is reflected in my enthusiasm in interviews and ability to "talk their ear off" if they are interested in the topic. Maybe I have it backwards, my enthusiasm for learning technologies is why I go deep in the first place.
