The correct answer is Nuclear minerals.

Renewable energy sources are those that are replenished naturally on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat. Wind energy, solar energy (from sunlight), and biofuels (derived from biomass that can be regrown) are examples of renewable energy sources. Nuclear minerals, such as uranium, are finite resources extracted from the Earth’s crust and are consumed in nuclear fission reactions to produce energy, making nuclear power (based on fission) a non-renewable source.

While nuclear power is low-carbon once operational, the fuel source (uranium) is not renewable in the same way as solar or wind energy. Nuclear fusion power, if it becomes commercially viable, would use more abundant fuels like hydrogen isotopes.
