Three weeks ago, I've replaced the gas stove with an induction stove (on overcapacity of my solarpanels) and heated the house with wood (trees felled by storms). I've spent €78 less on gas. Money that would otherwise flow to Russia.
@berkes woodsmoke is extremely dangerous to humans and is vastly more polluting than ng. your decrease in profit to russia is tiny. your damage to yourself, family, and neighbors is large. net loss.
