A natural resource such as coal, gas, or oil that, once consumed, cannot be replaced. Most energy resources currently in use are non-renewable while the renewable ones (such as wind and solar power) are not well developed. Also called depletable resource.
Explanation: The non renewable resources can be defined as the resources that once used cannot be replenished. The resources like oil and copper takes very long time to form and this makes it non-renewable.
The natural resources like oil takes a long time to form inside the ocean and its extraction is also done after long time because its formation takes time.
