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.
While nuclear energy is non-renewable, it is often considered a low-carbon energy source because the process of generating electricity does not produce greenhouse gases. However, concerns exist regarding nuclear waste disposal and potential accidents.
