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.

What are two kinds of resources found on the Earth?
Two kinds of resources found on Earth are renewable resources and non-renewable resources. Renewable resources, such as solar energy, wind energy, and biomass, can be replenished naturally over time. In contrast, non-renewable resources, like fossil fuels and minerals, are finite and can be depleted as they are consumed. Both types of resources are essential for human development and energy production.
Two examples of renewable resources are?
aluminum and copper
