Low density is always hard nut to crack because when distances are long and population is small, public transportation is not feasible.
One potentially great way to help mitigate the problem and help in both self sufficiency and carbon releases is biogas plants. In Finland there is close to 50 biogas plants build privately on farms. Its relativelly cheap to convert traditional gas engines to work with biogas. This is true for both farmin vehicles and cars. And it can be used for generating electricity. The plants also produces fertilizer as a by-product, so it helps with two recources that are traditionally imported from somewhere else.
