The world has changed a lot in just a few decades. we are a society that wants what we want, when we want it. 
Granted , for some families it
 is going to be a difficult time , and of course we are right to worry a little about people cutting back.
listening to the news constantly doesn't help.  It's better to play the field by our own experience  whilst being prepared to adapt and have a plan in place.
the house i grew up in was heated by a coal rayburn. we didnt have heating upstairs , unless we plugged in a radiator for a while before bed . I had a hot water bottle . and in the morning there was frost on the insides of the windows , when it was very cold .
we had an outside toilet also.
today , this would be classed as  living in fuel poverty.  however, i look back with fondness , it was just normal and we took measures  to ensure we were warm.
