Established in 1954, ASES is a 501(c)(3) non-profit that advocates for sustainable living and 100% renewable energy by sharing information, events and resources to cultivate community and power progress.

We integrate the perspectives of science, industry, policy and citizens. We believe knowledge and community are a powerful combination for change. Our members look to us to sustain the culture required to achieve a 100% renewable energy future.

Through our programs, Solar Today magazine, ASES Solar Conferences, National Solar Tour, Zero Emissions Network (ZEN), ASES Webinar Series, and Tiny Watts, we engage individuals, businesses and partnering groups to advance these possibilities.

ASES acknowledges the systemic injustice that impacts Black and indigenous people and other people of color as we work together to ensure that our transition to a 100% renewable energy future is equitable, inclusive, and just.

ASES convened a Justice, Equity, Diversity and Inclusion (JEDI) Task Force in October 2020 to enact this commitment and advance these values more broadly in the organization. Learn more about what ASES is doing to advance our JEDI commitment.
