A non-renewable resource is a material or substance that is finite and cannot be replenished over time. Synonyms for non-renewable resources include exhaustible resources, depletable resources, limited resources, finite resources, and non-replenishable resources. These resources play a vital role in critical industries such as energy, mining, and manufacturing, but their depletion poses a significant challenge to sustainability. The limited availability of non-renewable resources has made many researchers and scientists explore alternative sources of energy such as solar, wind, and geothermal power. The increasing demand for non-renewable resources has also led to the need for responsible consumption and conservation of these resources.
