Yeah, there usually are solutions for many people apart from the heating, and I suppose just restricting usage can help many.That works best for me also, just reducing energy
That's what I did the past few years already (just consume less), so I am well trained now. I was quite radical in reduction, and my energy bills dropped like 90%. I am now working on "eating" the fridge content, so I need even less energy.
I do have quite some food items in my house, so I don't worry for "no food" in the next 6 month or so
I used to get some things delivered - quite a lot of frozen foods and such - but given the shopping is so close, I will just do more shopping, hence the freezer going. I have a fridge/freezer anyway. I actually threw out a lot of frozen food when I switched the freezer off.
