The number of cities committing to 100% renewable energy goals continues to grow. And while left-of-center communities on the West Coast and New England have often led the charge, it is increasingly spreading across the United States.

Most recently, in December Ann Arbor pledged to power 100% of municipal operations with renewable energy by 2035, as reported by MLive. This will be a complement to the city’s Climate Action Plan and may include joining utility DTE Energy’s MIGreenPower program and/or installing solar on city properties.

And yesterday, Fayetteville Arkansas became the first municipality in the Southern state to commit to transition to 100% renewable energy. The city’s Energy Action Plan will include a goal to power all government operations with clean energy by 2030 and the entire community by 2050.

According to Sierra Club, this makes Fayetteville the 54th city in the nation to commit to 100% renewable energy, although Sierra Club’s list does not yet include Ann Arbor.
