Solar power as in stove with parabolic mirror - probably yes, solar power as in photovoltaic panel - probably not. The reason is that you can build one yourself and you can't the other.
No dependency during usage is less bad but you're still depending on manufacturer - and you want to avoid dependency.
Can they refine diesel and build an air compressor themselves? And I mean in practice, not theoretically.
In practice they most likely can't build a hammer or nails from scratch, because refining iron ore and making steel is quite complicated.
Can't diesel engines burn oil?
