In 2008, the Phoenix City Council approved a renewable energy goal for the city. The city aims for 15% of the electricity used by the city to come from renewable energy sources by 2025. This goal mirrors Arizona's Renewable Energy Standard of 15% of electricity from renewable energy by 2025. The city plans to achieve this goal through renewable energy installations that are either city-owned or city-sponsored, primarily through public-private partnerships. The city council will periodically review progress towards meeting the goal and will set milestones to track progress. The Environmental Quality Commission and Public Works Department collaborated to develop the recommendation.
