Net Generation of Electric Power
Net generation of electric power in Arizona is staying stable. After a sharp decline in the percentage of the total energy generated from coal, it has stabilized at slightly over one third of the energy produced in Arizona. Electric energy produced by nuclear power had also been declining, but has stabilized over the past few years at just under 30 percent. In contrast, the production of electric energy generated from natural gas had been on a steady increase, but after peaking at almost 34% in 2007, it declined slightly and has fluctuated between twenty and thirty percent of the energy produced. This leaves just a small percentage of the energy generated in Arizona from renewable sources, but non-hydroelectric renewable power continues to increase, especially wind and solar power, as long term drought takes its toll on hydroelectric production.
