... I thought oil was technically considered non-renewable because it takes hundreds of thousands (millions?) of years to form more oil, so when we run out, that's it, we'll have to wait for a long time, and by then, we'll already have a new power source and won't need oil anymore.

Wind is considered a renewable resource because it's always there, it's constantly being made. Same with sunlight.

Since we don't know how long it takes for Dust to form, or even how it's formed or what it's made from, we can't tell if it's renewable or not. It may not be.
