Uranium and fossil fuels - or if you like to be clever - fissile fuels and fossil fuels...
On the human time scale, fossil fuels are not being replenished. We can manufacture the same chemicals that are found in fossil fuels but we can't create new oil oil, coal and natural gas fields within our lifetimes - or for that matter within our 10,000 times great-grandchildren's lifetimes.
Once Uranium has been used (in a fission reactor) it is converted to isotopes of other elements and is not replenished by natural processes.
