Sami Sultan

Sami Sultan - President

Sami was born and raised in Houston, TX and currently works as an Integration and Governance Manager in Shell’s Renewables and Energy Solutions organization, developing renewables projects across the US. Before this role, Sami formed and led a wildly popular startup team within Shell, applying cutting-edge AI, analytics, and self-driving car principles to well navigation – resulting in seven patents.

Sami’s background is in Mechanical Engineering from the University of Texas at Austin, and he is simultaneously pursuing his MBA from the Yale School of Management, with a focus on sustainability. Outside of work, Sami enjoys chess, gardening, and building home science projects (particularly those with an energy flair!).

Sami is excited to align HREG with the Houston Climate Action Plan and allow HREG to drive home the commitment from the city and keep Houston as the Energy Capital of the World! Sami’s door is always open to answer any questions about being a part of HREG and growing the mission.

Juliane Surfus - Secretary

Julie has been calling Houston home since 2013, working as a chemical & biological engineer at Dow in hydrocarbons manufacturing and supply chain roles.  Over the last year, she realized how strong her interest in clean energy production and environmental sustainability was, and has been expanding her knowledge ever since.  Whether it’s listening to her favorite renewable energy and climate change podcasts on her commute to work or asking questions and learning from others, she is passionate about more directly aligning her professional experience towards helping advance renewable technologies.

If you miss her at the next HREG meeting, you will likely find her at the next WRISE event.  Julie wishes she had known about HREG sooner and encourages anyone to join our community, even if you don’t exactly fit the renewable energy job mold.

Bill Swann – Education & Solar Workshop Director

I walk and talk the message of going green. It’s easy. Purchase an electric car. I did. Don’t purchase ancient stored solar energy (fossil fuels) but rather purchase recently stored solar energy (wind power) or immediately stored solar energy (photovoltaics). I did! Educate others. I do by leading the monthly solar workshop.
