What's the meaning of "power" in this context?
"The changing climate of the planet and the remarkable growth in human numbers and riches both stem from the combustion of billions of tonnes of fossil fuel to produce *industrial power*, electricity, transport, heating and, more recently, computation."

-
Does "power" here mean "nation", as in "The U.S. is a leading industrial power"? or it can never be that since "power" to mean a nation requires an article, "a/the"??

Or "power" here means ability and authority?
