Ever wondered what lies beneath your feet? The potential of geothermal energy is explored in this third instalment of Climate Conversations. Find out what it's like below the surface, and how now-disused mining infrastructure could be repurposed to heat homes in years to come. With Johann MacDougall of the Scottish Government Onshore and Subsurface Systems Policy Unit, Bob McDonald & Colin Finlay, co-authors of A History of Coal Mining in Rutherglen and Cambuslang, and Dr Alison Monaghan, science lead at the Glasgow BGS site. These conversations are the opinions of the contributors and not necessarily the views of NERC.
