September 21, 2025 @ 2:00 pm – 4:30 pm
Sunday, September 21 is a day of action to celebrate solar and wind power, and the widespread adoption of renewable energy sources in Texas and worldwide.
Sun Day Houston 2025 will feature inspirational speakers at 2 p.m., exhibits throughout the event, workshops at 3 p.m. (Rain Barrels for the Houston Area Community), 3:30 p.m. (Tips & Tricks for Going Solar) & 4 p.m. (Welcoming the Energy Transition), a Voter Registration Booth (from 2 – 3 p.m. only), music, fun activities, food, and fellowship that focus on learning what actions individuals can take to counter climate change and promote the adoption of clean, reliable energy statewide and on a small scale in communities, businesses, homes, and apartments.
Attendees will see mobile solar and home solar battery displays, electric vehicle show and tell, and other hands-on renewable energy demonstrations. Rain barrels will be sold at the event; reserve a rain barrel in advance at www.galvbay.org/events, because they will sell out quickly.

“Solar and wind power have become the most affordable sources of new electricity generation in Texas and worldwide, while in Houston—a city long shaped by the hydrocarbon industry—misinformation about the cost-effectiveness and reliability of renewables persists. Sun Day Houston 2025 is about providing accurate, unbiased facts to the public empowering our community to make informed choices for the future,” said Gina Biekman, coordinator of the Third Act Houston Working Group, primary sponsor of the event.
Featured speakers:
Daniel Cohan, PhD, Professor of Civil and Environmental Engineering at Rice University, will speak on the science of renewable energy and its growing role in ERCOT and the national U.S. energy grid. Dr. Cohan will also highlight his own personal experience with rooftop solar and his electric vehicle.
Andrea Oyuela, Sustainability Division, Harris County Office of Administration, is manager of the Harris County Solar for All program. Andrea will share updates on Harris County’s efforts to expand solar energy access to underserved communities in our area and the county’s leadership role in the Texas Solar for All Coalition. Andrea’s international development experience includes projects in Kenya, Norway, and Italy.
Information on Workshops:
Rain Barrels for the Houston Area Community: Learn about the benefits of rain barrels, get one for your home/house of worship and learn how to install it on your property. Rain barrels not only conserve water, a precious natural resource, they also help to keep water clean and reduce flooding, thereby making Houston a more resilient city. And, these barrels have been re-purposed, avoiding plastic waste. Registration includes one rain barrel, one connecter kit and training to install them. Supplies of rain barrels are limited, so please register early. Rain barrels will be available to be picked up on Sunday, Sept. 21, from 2 – 3 p.m. in the church parking lot. Installation training will take place afterward, from 3 – 3:30 p.m., with Q&A/wrap-up from 3:30 – 4 p.m., in the church building. Galveston Bay Foundation will share a presentation discussing water conservation tools like Water My Yard, the environmental benefits of reducing freshwater usage and collecting rainwater, as well as proper rain barrel preparation, installation instructions and tips. If you can’t stay for the training, recorded training is available. This workshop is organized by Galveston Bay Foundation in partnership with the Interfaith Environmental Network of Houston, and is sponsored by Coca-Cola Southwest Beverages. Register to participate at: www.galvbay.org/events.
Tips & Tricks for Going Solar: Sophy Ashworth, a long-time solar homeowner and volunteer with the non-profit Solar United Neighbors (SUN), will share from her and SUN’s experience how best to invest in solar, avoid scams, and hedge against rising electricity costs. Bring your questions and between Sophy and SUN’s great Help Desk, we will help take down the barriers to going solar. Already have solar? Thank you! Sophy will share how to help SUN advocate for our solar rights. Please register for this talk on https://www.mobilize.us/solarunitedneighbors/event/830764/.
Welcoming the Energy Transition: Nan Hildreth will provide citizens with keen insights and statistical data to elucidate the energy revolution that we are in the midst of, right now, even though few have noticed it. “We must recognize it and pursue it swiftly and wholeheartedly to end the climate crisis,” Nan says. This workshop will display how clean energy has become the cheapest source of energy and is doubling every three years. 95% of new electricity generation in 2024 was solar, wind, or battery-supplied from clean energy. By 2050, humanity can expect to accomplish twice as much with only a fraction of current emissions. Fossil fuels waste 2/3 of the energy created. Clean energy adoption is as unstoppable as was the Industrial Revolution. Yet some are trying to slow it down.
Join us for a fun day of triumph to celebrate the success of widespread renewable energy adoption and learn how you can advocate for change! Register for the Sun Day event, for planning purposes, at: https://actionnetwork.org/events/sun-day-houston
