Why are domestic fuel sources preferable to international fuels sources?

Domestic fuels do not require combustion.

Acquiring fuels from abroad can pose a national security risk.

Domestic fuels are always cheaper to acquire and renewable.

International fuels will run out before domestic fuels.

Domestic fuel sources are preferable to international fuel sources because domestic fuels are always cheaper to acquire and renewable. The correct option in regards to this question is the third option given. The fuel that the country imports will definitely cost higher and there is no doubt about it. The fuels that are present can be replenished very easily without having to wait for the imported fuel to come in. The imported fuel rate will also vary and sometimes may become too highly priced. So depending on national or domestic fuel sources is always a better option compared to looking out for international sources.
