I am from Eastern Europe (Latvia) and this does mostly hold true for the countryside: wood burning stoves are common.

However, it is likely that inflation and other cost increases will also affect the prices of firewood from here on out, as well as getting it delivered (unless you decided to secure your own, though depending on where/how you do that, the legality might be dubious).

From what I know of, most people are noticeably hit by the increase of prices in the stores (as well as a somewhat decreased selection of what's available), in addition to greatly increased electricity prices, which has been a topic that gets brought up often in the news.

There aren't that many great solutions for that, to be honest - both diesel generators and solar panels are too expensive for most people, even though there are programs to aid families with purchasing and setting up their own, if they're capable of partaking in those: https://www.altum.lv/en/services/individuals/energy-efficien... (the Latvian translation has more information https://www-altum-lv.translate.goog/pakalpojumi/iedzivotajie...)

That said, it's probably difficult to undertake something like that, when you're living from paycheck to paycheck.
