The podcast episodes examine the critical role of minerals like nickel, copper, and lithium in enabling the transition to green energy technologies, such as electric vehicles and renewable power generation.

Several episodes explore the challenges of securing reliable and sustainable supplies of these critical minerals, including geopolitical tensions, environmental and social impacts of mining, and the need for innovation and recycling in the metals industry.

The episodes also discuss the broader economic and policy implications of this transition, such as the Biden administration's 'Bidenomics' policies, the impact on industries and workers, and the potential to reshape the global economy towards a more sustainable model.
