Question: when will the world run out of coal and oil

Sarah Montgomery answered on 20 Mar 2025:

There is a limited amount of coal, oil and gas (fossil fuels). But in practice, some of it is easy and cheap to extract, and some is hard to reach so it’s expensive to extract. So rather than running out, we will probably reach a point where extracting what’s left is more expensive than using alternative energy sources like nuclear power.
