Arizona is divided into two major physiographic provinces. Most of the older fuel resources are located in the Colorado Plateau Province that lies in the northeastern two-fifths of the state.

 Energy Source Comments
Coal Probably most abundant energy source in the state; located at Black Mesa (3200 mi² on Navajo and Hopi reservations in northeastern Arizona) with bituminous and sub-bituminous coal types; train from mine to Navajo power plant at Page, AZ and slurry pipeline to Mohave plant in Nevada (1 mile west of Bullhead City, AZ). Coal-fired units: Cholla, Coronado, Navajo, and Four Corners (actually in New Mexico).

Petroleum Some production in northeastern corner of the state. Several oil/gas-fired plants.
Natural Gas Virtually no production in AZ. Most are combination oil/gas-fired power plants such as Ocotillo, Kyrene, and Santan (a combined-cycle plant) in the Phoenix area.
Hydroelectric Most dams in Arizona are designed for water storage. Biggest dams at Hoover (Lake Mead) and Glen Canyon (Lake Powell). Other dams on the Colorado River are Parker (Lake Havasu) and Davis. Only additional sites on the Colorado River are at Bridge and Marble Canyons in the vicinity of the Grand Canyon. SRP also operates several dams.

Uranium Mining operations in northern part of state. Three-unit Palo Verde Nuclear Generating Station 50 mi west of Phoenix. Also see Palo Verde Nuclear Generating Station from APS, Palo Verde Nuclear Generating Station (PVNGS), and the PVNGS Unit #1 Information Book from U.S. NRC
Solar Excellent areas in Arizona for solar collection. Arizona has the highest mean hours of total sunlight of any state in U.S.
Geothermal Two possible locations: (1) Power Ranch just southeast of Phoenix (180°C at 2 miles), and (2) Exxon hole south of Tucson (146°C at 12,556 ft).

Wind Windiest spot is Arizona is ironically called Winslow (Wind-so-low). The average wind velocity there is 8.3 mi/hr.
