Actually warming up cold places in winter is more energy intensive than cooling down hot places. Nordic countries should not exist by that logic.
- mistrial9 5y agoI have to deeply question this.. it might take some research..
- fouric 5y agoThis is false. Heat is an incredibly common type of waste energy, and far more common than waste "cold" (if such a thing exists at all), so most (if not all) heating devices are more efficient than cooling devices. Furthermore, heat is related to entropy, which in a closed system can only increase. We have many devices that can generate heat where there was none previously (e.g. resistive heating elements) but none that can destroy heat, only shuffle it around somewhere else.
- AbrahamParangi 5y agoThis isn’t really true because pumping heat requires less energy to create the same differential than generating, and most homes are heated by generation.
