Nuclear energy is considered a source of non-renewable energy because it relies on finite natural resources, primarily uranium, which is mined and processed. Once the usable uranium is depleted, it cannot be naturally replenished on a human timescale.
– Non-renewable energy sources are those that exist in a fixed amount or are consumed faster than they can be replenished naturally. Examples include fossil fuels (coal, oil, natural gas) and nuclear fuels (uranium).
– Renewable energy sources are replenished naturally over short periods. Examples include solar, wind, geothermal, hydropower, and biomass.
