Arizona regulators have approved a plan that will require utilities in the state to receive all their power from carbon-free sources such as solar and wind by 2050.
The Arizona Corporation Commission last week passed the measures, which also include interim carbon reduction targets for regulated utilities of 50% by 2032 and 75% by 2040.
The rules update the state’s 2006 renewable energy standard that requires utilities to source 15% of their power from renewables by 2025.
