As the world transitions to renewable energy, the development of wind and solar farms is accelerating at an unprecedented rate. Solar energy, harnessed from the abundant solar radiation that reaches Earth, is virtually inexhaustible. However, the materials needed to produce solar panels are limited. This project explores the photovoltaic panel supply chain and identifies potential challenges that could arise as we aim for a shift to 100% renewable energy sources. Are there sufficient materials available to meet our future needs?
