If you keep your house between 63 and 65 as most of the people in the world do in very cold climates, you will save a lot of money on your heating bill. It seems most Americans believe they must heat their homes to 72 or above. It you just wear warm clothes and a sweater, you don't need the higher temperatures. When I was a kid, we spend a winter in northern England and we learned to dress properly for winters indoors.It's easy to stay warm. Most every American can. It's paying these outrageous energy prices in which TO stay warm.
