english: All of this extra water that's being boiled requires energy, and it's been calculated that in one day of extra energy use from boiling kettles is enough to light all of the streetlights in England for a night.
non_english: Prebytočnú vodu treba ohriať, na čo potrebujeme energiu. Zistilo sa, že za deň premrháme na ohrev vody toľko energie, že by to stačilo na osvetlenie ulíc v Anglicku na celú noc.
