This presentation was delivered at the New Economy Network Australia 2018 conference in Narrm (Melbourne). (https://www.neweconomy.org.au). The aim of the presentation was three-fold. First, contextualise the national energy conversation prior to the installation of Tesla’s 'big battery’ at the Hornsdale Power Reserve in South Australia. Second, problematise the battery's inception on Twitter, its lithium-ion composition, and the media discourse that never explicitly addresses excessive energy usage as a cause of grid instability. Finally, third, propose that while the big battery industry is still seeding in Australia - & before the controversy settles - an opportunity exists to normalise new socio-ecological practices (such as our appetite for energy) that works within our planetary boundary and confronts climate change. I emphasised that this proposition is possible by relating it to the battery icon on our mobile devices (the icon is a communication strategy that influences energy practices). I then concluded by explaining how Earth is a 'battery' and proposed the question of how to take our relationship with our mobile device battery and scale it to big batteries (that support renewable energy), and to the 'biggest' battery (Earth).
