Percent of Electric Power Generation in Arizona by Renewable Sources
The production of electric power from renewable sources has been declining since 1997, when it peaked at 15.4% of total production. In 2011, electric power from renewable sources was 9.0% of the total energy generated in Arizona, the highest percentage in a decade and an encouraging sign, although it declined slightly in 2012. The Renewable Energy Standard and Tariff (REST), approved by the Arizona Corporation Commission in 2006, mandates that 15 percent of energy production in the State of Arizona be from renewable sources by 2025, although, for the most part, hydroelectricity does not help to satisfy this requirement. Much work needs to be done on increasing renewable energy sources in Arizona to meet this goal.
