Tesla's Powerwall 3 is set to gain compatibility with the older Powerwall 2, offering a seamless upgrade path for existing customers. This feature, currently rolling out in Australia, is a testament to Tesla's over-the-air (OTA) update infrastructure, allowing for complex software changes without the need for physical interventions. The announcement comes as Tesla Energy continues to thrive in Australia, one of its largest energy markets, alongside North America. This backwards compatibility feature is a significant win for energy independence, as it allows customers to retain the value of their original investment while expanding their home energy ecosystem. Tesla is also making strides in battery sustainability, reclaiming the top spot in the 2026 Lead the Charge automotive supply chain leaderboard. The company's focus on vertical integration and supply chain transparency has led to a 20 percentage point score increase in the battery section, becoming the first to score over 50% in this category. Additionally, Tesla's commitment to recycled materials is evident through a new offtake agreement for low-carbon aluminum in North America, further reducing its environmental impact. In Europe, Tesla's Giga Berlin facility has reached a turning point in its labor relations. The German metalworkers' union, IG Metall, failed to secure a majority in a works council election, allowing Tesla to proceed with its expansion plans. CEO Elon Musk's pre-recorded address set out a massive expansion plan, contingent on the factory remaining free of external influences, particularly labor unions. The election results, with a high voter turnout, signaled a clear preference for independent co-determination, paving the way for Tesla's ambitious growth trajectory.
