I work from home and only put about 3000k miles on my Jeep. My wife commutes, but uses an PHEV with enough electric range to easily make to work where she can then charge for free as a work perk. We also live a half mile from a train station and plenty of amenities.
However, our home furnace uses oil. The last top off, 169 gallons, was $898. It was about $600 before the war. We have to fill it about three times a winter/fall/spring. Bad timing, but at least it's now officially spring. But we do have two fireplaces and buy seasoned hardwood by the cord for about $220. We could definitely burn more wood to offset more oil if it came down to it. With our typical use we go through a cord in about two and half winters when leaving the furnace at 65 F. This past autumn we had to fell a 80'+ ash tree which should provide the better part of a decade worth of fires once it is all seasoned. We have about twenty other trees over 80' on the property. We will probably get solar panels and battery backup within the next five years.
Also #$%* the stupid war of choice. Completely unnecessary. Completely run by lying piece of feces. Evil murdering sociopaths, the whole lot of them.
Never rely on others for you safety and security if you can help it. Yes, I know I obviously can't completely help it with my lifestyle either. But my eggs are not all in one basket. I am the ant, not the grasshopper. It has been decades in the making. I had a three month period when I crashed at a friend's apratment on their coach when I was in college. Hopefully if/when society collapses, I will be further towards being more self sufficient. And if it never collapses, the definitive preferred option, the worst case is that I am still isolated against price increases in retirement.
