This report is a nontechnical swnmary of the energy resources of Arizona intended to accompany the Energy Resources Map of Arizona. Arizona is endowed with a variety of energy resources and potential resources; each is given its own chapter in this report. Chapters are arranged according to the relative importance of each resource to the State, with the most important described first. Coal is discussed first; the next three chapters address hydroelectric power, uranium, and petroleum, the other important traditional energy resources. Geothennal, solar, wind, and biomass energy, usually considered' 'alternative" energy resources, are treated in the last four chapters of this report. They have considerable development potential, but as of 1991 have not been exploited on a significant scale.
