How do you handle it when a kid like this brings up some sort of major world problem/issue? DS started asking about gas/oil the other day. He's very concerned that we are digging oil out of the ground and burning it all up in our cars, and then we are going to run out, and then what will we all do?
We are not running out of oil. Not by a long shot.

And NOTHING is sustainable. Second Law of Thermodynamics. In practical terms, this means that every machine wears out and also require human attention when they do run.
Solar/Wind are terribly inefficient from a thermo standpoint and this is why they are also cost prohibitive.
