english: They give off a lot of heat into the atmosphere, and for some of you may understand the heat island effect in cities, where the urban areas are much more warm than the adjacent rural areas, but we also have problems that, when we lose power, we can't open a window here, and so the buildings are uninhabitable and have to be made vacant until that air conditioning system can start up again.
non_english: Oni odaju mnogo toplote u atmosferu i neki od vas mogu razumeti  efekat termalnog ostrva u gradovima, gde su urbane oblasti  mnogo toplije nego okolne ruralne oblasti, ali takođe imamo i problem da,  kada nestane struje, ne možemo tu otvoriti prozor i tako su zgrade nenastanjive i moraju biti prazne sve dok sistemi klima uređaja  ne počnu da rade ponovo.
