I live in a small, self-built house in a village in northern Laos. I have no heat and no air-con (neither are necessary), light exclusively with compact fluorescents, and have 2 computers. All my cooking is electric, using an electric wok and an induction plate. I have a 4.4KW instant water heater in my shower.
My electric usage is 200 to 300 KWH per month, and bill is typically $15 to $20. My highest bill ever was $25.
I'm considering installing a solar water heater, which should reduce it by $5 a month or so.
