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: Bettina Pierre-Gilles

Bettina Pierre-Gilles brings several years of strong corporate finance expertise, management and general industry knowledge to the Board. Currently, she is the President & CEO of a startup Independent Power Producing (IPP) company named Luxeum Renewables Group Inc., a Calgary based solar producing company with the strategic objective of developing utility-scale solar projects in Alberta and Western Canada. She has been the President & CEO of a well-established Consulting firm focused in the energy industry, as well as servicing clients in various related industries. 

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.

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.

Past Chair: Réal Bouchard

Réal is a long time solar pioneer who has had the honour of working directly with some of the brightest minds in the industry. He has been a fixture in the Alberta solar market since 2006 (which in solar years equates to a whole lot more than 10!) where he has lead in various positions with a few different companies. His longest tenure was with Conergy, which at the time was a publicly traded multinational company where he was the director of operations & finance for Canada. Réal recently completed his MBA from the University of Alberta (Dec. ’15) where he focused his degree in the areas of strategic management and corporate finance. He is also an alumnus of St. Francis Xavier University.

Member at Large: 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.

Member at Large: Desmond Bull

My name is Desmond G. Bull, I am an elected councillor for the Louis Bull Tribe of the Maskwacis nation. Prior to my work in governance I was employed in the field of education for 12 years. As a first nation member, elected official, and environmental steward I was honored to develop and secure funding for a community photovoltaic system in Maskwacis. We completed our project in August 2016 with a ribbon cutting ceremony which was attended by government officials, stakeholders, and leadership. This work also opened opportunities for me to sit with The Alberta Green Economy Network, Energy Futures Lab of Alberta, and be appointed to the government of Alberta's Energy Efficiency Advisory Panel. In 2017 I also joined the 20/20 Catalysts program. In Maskwacis we are currently working towards the completion of our next proposal for the rest of our public buildings. I am also building connections between SESA and First Nations, and helping SESA showcase the work of First Nation leaders in solar energy.

Member at Large: Greg Cole

Greg is the founding member of EnSegs. He started EnSegs to create simple ways for people to own and produce their own renewable energy. His home is powered by a 5.2kW solar PV system. Greg has graduate degrees from the University of Alberta in both education and business.
