Episode #007 of The Solar Journey Podcast is a little different than our previous episodes. Our honored guest is Alexandra Münzer. She was introduced to us as the “Mother of European Guarantees of Origin,” and we used the opportunity to take a deep dive into a very complex topic: The scope and application of the Guarantees of Origin (GOs) System (also known as green certificates) in Europe. We peppered Alexandra with questions about the purpose, practical application, and possible shortcomings of the GO-System. This system is at the heart of Europe’s goal to become the first carbon-neutral continent by 2050. We learned a lot and are excited to share these fundamental insights with our listeners.
