This article analyses the geographies and politico-economic dynamics of Sydney's multiscalar renewable energy transition. Sydney's energy economy seems to be dominated by marketisation, privatisation, and fossil fuel-generated electricity, yet simultaneously a decentralised renewable energy transformation is unfolding. In this context, we ask how do politico-economic and technical changes co-evolve within the renewable energy transition? What tensions exist among different actors, institutions, and markets across changing energy geographies? Drawing from field research, including key informant interviews with various renewable energy stakeholders, we characterise the renewable energy transition in Sydney as inherently relational and in tension rather than as simplistically binary. In particular, three dynamics of relationality considered here are foundational in the push and pull of energy geographies in Sydney: fossil fuels and renewable energy sources; neoliberalisation and democratisation; and system and local scales as sites of action. After mapping those out, we conclude by questioning the long-term impact of neoliberalisation on emergent, more democratic approaches to energy.
