I agree. skip the generator and skip batteries for now.
Put some ice blocks on your fridge that will help it stay colder longer and run less often. Also add some rigid foam insulation around the outside of it and the door (don’t cover any cooling coils or fans or anything like that) OR get a small chest freezer and use it as a fridge, you can often find them used for cheap or free. Freezer tend to be better insulated also a top opening chest freezer is less convenient to store/organize stuff in but it holds cold better because it doesn’t dump out the door every time you open it.
I would agree. Biochar and charcoal are fundamentally different, and it’s unfortunate that the two get conflated. Biochar is produced at higher temperatures then charcoal and doesn’t add to atmospheric carbon dioxide levels during production (if produced correctly). On the other hand charcoal is produced at lower temperatures and is not clean to produce so does add to atmospheric carbon dioxide levels.
this seems like a pretty good general overview: https://rosysoil.com/blogs/news/biochar-vs-charcoal
