Board of Directors

Chair: Susan Petrina

I believe in the power of people to change their circumstances for the better so long as they are provided with knowledge, tools and support. My combined interests in architecture, sustainability, renewable energy and advocacy contributed to the path that led me to get involved with SESA. Prior to joining the board in 2014, I attended many SESA seminars and events for general information and was impressed by the supportive and growing community of renewable energy enthusiasts in Edmonton and across Alberta. SESA has played a pivotal role in shaping the conversation around energy sustainability in the province and I felt it was time for me to jump in and get involved.

I have a diverse professional background that includes politics and government, communications and marketing, and extensive work with non-profits in community development, civic engagement and creative strategic planning. My credentials include an honours degree in sociology and a journalism diploma. I’m an experienced facilitator who gets excited by the prospect of bringing people together to accomplish things. And just for fun, I’m also leading a great group of neighbours to build a new community centre that we hope will be a model of sustainable design and energy efficiency.

Vice-Chair: Elizabeth Andrew

Beth Andrew is a Renewable Energy Technologist working for Great Canadian Solar where she works in design and sales. Beth was a part of the first class to graduate from NAIT's Alternative Energy program. Beth believes that SESA offers an important link between the Alberta solar industry and the public, and that education is the best way to promote solar technology.

Treasurer: Ron Kube

Ron is a research scientist, specialising in intelligent systems, and an adjunct professor at the University of Alberta. After graduating in 1997, he did his post-doc at a small Edmonton start-up company applying software to electric load forecasting on the provincial grid. In April 2000, he was invited by NASA to come to Washington to discuss the use of robots to build space power systems that deliver massive amounts of solar energy to the Earth’s power grids. It was there, he was impressed by the sense of urgency to develop a truly low-cost renewable energy option for baseline electric power on a global scale. His revived interest in renewable energy, after spending 17 years working in Alberta’s non-renewable energy sector, is what has brought him to volunteer with SESA.

Secretary: Karlie Nelson

As a graduate of the NAIT Alternative Energy Technology program and the Inside Salesperson at National Solar Distributors, Karlie is happy to be contributing to the growing renewable energy industry both as a technologist and a SESA board member.
