- The global transition to a low-carbon economy will involve changes in material markets and supply chains on a hitherto unknown scale and scope. With these changes come numerous challenges and opportunities related to supply chain security and sustainability. To help support decision-making as well as future research, this study employs a problem-oriented perspective while reviewing academic publications, technical reports, legal documents, and published industry data to highlight the increasingly interconnected nature of material needs and geopolitical change. The paper considers a broad set of issues including technologies, material supplies, investment strategies, communal concerns, innovations, modeling considerations, and policy trends to help contextualize policy decisions and regulatory responses. Policy options are outlined for each topical section, as well as areas for further research. Together, these recommendations serve to help guide the complex, interdisciplinary approach to materials required for a low-carbon transition.

- This paper presents the results of an analysis that explores how Typical Meteorological Year (TMY) informed power system models perform when exposed to atypical variability. A simplified power system planning model is tested for two case studies in Guinea-Bissau and Turkey. A TMY proxy is compared against 24-year timeseries datasets containing hourly resolution solar PV and wind capacity factor data. Results show that unforeseen shortages in VRE generation and additional expenses are approximately 36 GWh and 10 million USD for Guinea-Bissau, and 92 GWh and 232,000 million TL for Turkey. Moreover, Turkey faces unmet demand of up to 50 TWh. For Turkey, unmet demand is penalized at 5000 TL/MWh, explaining the high cost increase. The underperformance of the TMY-based simulated system also is responsible for 45.77 million kg of unforeseen CO2 emissions in the case of Guinea-Bissau.
