Unlike the US where we are the land of plenty, and therefore plenty of waste; Chilenos are much more energy efficient. One the ways I have adapted is in heating water for dishes and a shower. Houses and apartments here have gas flash heaters. I only do dishes in the morning, because I light my heater, do the dishes, take a shower, then turn the heater off. Like all the Chilenos I have met and observed, this saves on the gas that would normally be wasted in leaving the pilot light on all the time when not in use. It seems small, but it adds up.
