Norma and Alan Williamson are a husband / wife team who in 2003 renovated their home into an energy efficient solar home.

As it generates more energy than it consumes, it is technically a zero energy building.

Alan is a certified Building Performance Institute technician and photovoltaic specialist with 20 years of experience.

Norma is a retired teacher, environmental project leader, and was named 2020 Woman of the Year by

Assemblywoman Cristina Garcia from Assembly District 58.

Norma Williamson received the Green Schools award for the numerous environmental literacy grants that she wrote

for her La Mirada High School students from 2004 to 2018, all totaling approximately $300,000.

Since 2001, Norma and Alan have been driving a 100% electric vehicle (EV) and Norma hasn’t been to a gasoline station since. Before the age of public EV charging stations, when she and Alan would take road trips, they would carry a portable car charger in the back of their EV and charge up at either RV campsites or hotels, where they would plug the charging unit into their hotel room electrical socket and run the cable through the hotel window out to their EV, which was parked directly in front of their hotel room.

For several years, from 2004 – 2008, they opened their solar, net zero, energy efficient home to the public for the annual National Solar Tour, sponsored by American Solar Energy Society. On one Saturday, they received 250 visitors, which led them to an invitation to submit an article on their home to Solar Today magazine, which became a cover story.


For close to 15 years, Norma & Alan have been giving power point presentations to community groups on

how people can convert their existing homes into carbon free energy homes.

Thanks to a young electrical engineering student from Cal Poly Pomona named William "Bill" Korthof, we were guided through our home's energy renovation process. Despite being in his early twenties, he was the owner/president of Energy Efficient Solar, an electric solar installation and energy efficiency company in Pomona, California. Unfortunately, we lost him and his climate activism in 2014 at the early age of 36 due to a fatal motorcycle accident.
