Geek Out Number Three - Energy! Richard chats with Carl about the state of power generation in the world today - the growth of wind (offshore wind is growing!) and solar, why geothermal isn't taking off, and then a long conversation about small modular nuclear power. Is SMR really going to be a thing? 2021 also had a lot of news around fusion - much of it just noise, but there have been some important developments that might actually mean fusion is getting closer! The energy Geek Out wraps up with power storage, including thermal storage, different types of battery storage, even the potential of hydrogen! Lots to geek out about!
