One of the confusing aspects of talking about energy is that different people use the same word (or words) to mean very different things. Sometimes energy means electricity, sometimes it means power. In Calgary some people even say "We have both kinds of energy: oil AND gas!" What do we mean? Why do people mean different things when they use the word energy.

One of the confusing aspects of talking about energy is that different people use the same word (or words) to mean very different things. Sometimes energy means electricity, sometimes it means power. In Calgary some people even say "We have both kinds of energy: oil AND gas!" What do we mean? Why do people mean different things when they use the word energy.
