I grew up during the 1970s energy crisis in the US.
It was just radiators and single-glazed windows ...
I never turn the thermostat above 68 in the US.
I grew up in a 150 year old house in Wisconsin...
Another New Englander ...
Yeah, well my dad was a meteorologist for the NOAA, and we lived at a weather station in Antarctica, about a 10 minute walk from the South Pole.
Because it was the 70s and the US was bankrupt from the oil crisis and having spent all its money sending men to the Moon, there wasn't enough money for heat or food at the station, so in order to slow our metabolisms enough to make our food last, we spent 364 days per year encased in blocks of solid ice.
Once a year on our birthdays, penguins would peck us out of our ice block and we'd get a grilled cheese sandwich and a cupcake with a wind-resistant candle in it, and then it was back into the ice for another year.
So the stupidity of English methods of dealing with its climate doesn't bother me, because I'm totally impervious to cold. I'm typing this on my laptop, sitting outside in my garden, drinking an ice cold Coca-Cola™, wearing not a stitch of clothing.
