What We Do

New Energy Colorado, is a non-profit with deep roots in Colorado’s solar and environmental communities. We work to provide education on energy issues to citizens as a 501(c)(3) non‐profit organization. We believe that an informed citizenry, who we are organizing as Climate CitiSuns, will play a vital role in the transformation from centralized fossil fuel energy to a system built on renewables and more customer choice.  In addition to our Climate CitiSuns program we organize the annual Metro Denver Green Homes Tour  - over 25 year running and also the Ark Valley Green Homes tour each year.

Climate CitiSuns

Overwhelming majorities of Coloradans want more clean energy. Yet these passionate residents–whom we call Climate CitiSuns–have had little opportunity until now to build a community that can grow into a powerful voice to advance climate policy. Colorado was a leader in launching the movement toward solar energy but we are now falling behind other states with more advanced policies. Climate CitiSuns is a community of folks who want to hasten the clean energy transition.


This community will allow residents to compare notes via social media, learn about climate‐themed events, and get educated about how to participate effectively at the Public Utilities Commission, at the legislature, or in front of local governments. Sign up today to become a Climate CitiSun–it’s free and easy and will put you in touch with thousands of like‐minded Coloradans!

Annual Metro Denver Green Homes Tour
The Tour has been in the Denver area for twenty-seven years, with similar events in all fifty states. This self-guided tour coincides with the American Solar Energy Society's National Tour of Solar Homes and features homes that demonstrate a wide range of strategies from remodeling options to full-on passive solar design to an entire community focused on clean, efficient energy. Spend an hour or a full day exploring both new homes and homes that have a history of performance in Centennial/Littleton, Denver, Golden, Morrison and Wheat Ridge.

Other Environmental Activities


Golden Earth Days, the predecessor organization to New Energy Colorado, worked for a quarter century on a variety of local environmental initiatives including clean­ups of Clear Creek Canyon, tree­planting campaigns and other activities. Those who spearheaded these activities intend to continue under the New Energy Colorado name.
