On the night of 30 October, I was sitting alone in a small train cabin somewhere between Przemysl and Kyiv. It had been about a week since Russia had started to strategically target Ukrainian energy infrastructure, to cause maximum suffering as the winter was approaching. Every morning, there was worse news – 20% of infrastructure damaged. Then 30%. Then 40%. The bombs and drones caused damage faster than Ukrainians could repair it, despite performing miracles with scarce resources while being in constant, mortal danger.
