This report was made possible through the generous support of Energy Consumers Australia via the Gill Owen Scholarship. The scholarship enabled first hand research in California, comparing its energy transition policies, regulatory design, and electrification challenges to those in Australia. With the urgency of climate action and rising energy costs, this research aimed to assess how both jurisdictions are reforming their gas and electricity systems. This report combines seven articles into thematic chapters covering gas phase-out pathways, rule reform advocacy, equitable electrification, and regulatory innovation. It compares efforts to support vulnerable communities, tackle grid bottlenecks, and plan for precinct-level energy transformation. Each article is presented as a standalone chapter, preserving its references
