What Our City is Doing


Thornton's Energy Vision: Thornton will lead the way in creating a more resilient community through energy efficiency improvements and the adoption of energy sources that reduce carbon emissions from municipal operations while also facilitating equitable access to energy programs and opportunities for residents and businesses.

In 2019-2020, representatives from the City of Thornton, Xcel Energy, United Power, GRID Alternatives, and Adams 12 Five Star School District worked together to create Thornton's first Energy Action Plan through Xcel Energy's Partners in Energy Program. Now the City of Thornton is working to implement this plan, to move the Thornton community toward its energy efficiency and renewable energy goals.

Home Energy Squad® is the perfect way to begin your journey toward lower energy bills and a more comfortable, more efficient home.
