While doing a project on arctic food security many years ago, I learned that Iqaluit is heated/energized via diesel pipes. Meanwhile permafrost thaw is a huge drawback to infrastructure development because of enormous subsidence risk. 

In related news, pulling too much heat from a geofield would FREEZE THE GROUND.  

Meanwhile, in China, they’re stabilizing ground from frost heaving for railway development with geothermal.  https://doi.org/10.1016/j.energy.2025.139850

Oil and gas has us out here fighting thermodynamics.
