Pros

Talented, committed people and meaningful mission in renewable energy. Strong collaboration at the team level.

Cons

Leadership decisions often feel disconnected from on-the-ground realities, with limited transparency or accountability. Female representation in senior leadership is noticeably lacking, which impacts culture and decision-making. Given current market and policy uncertainty, the short-term outlook for renewable energy in the U.S. is challenging, and unclear if we are clearly aligned to navigate it.
