In this episode of The Magic is in the Science, Zama Moni chats to Mark Teepelt, an expert in renewable energy, about the real potential of biogas in South Africa. From cow dung to kitchen waste, we explore how everyday organic material can be turned into a reliable energy source, and why it’s more than just a backup plan. Mark breaks down the science behind biogas in a way that makes sense, touches on its impact for households and communities, and challenges the idea that clean energy is out of reach.
