non-renewable resource

/nɒn-rənjuəbəl ˈrisɔs/ (say non-ruhnyoohuhbuhl 'reesaws)

a natural resource which, once it is depleted, cannot be replaced or restored, such as fossil fuels.
A non-renewable resource is a natural resource that exists in a fixed amount, and is used up by humans at a rate faster than it can be made by nature. Non-renewable resources include fossils fuels such as coal, oil and natural gas which are developed by geological processes over millions of years, and minerals such as iron ore, aluminium, gold, and phosphate rock, which are developed by geological processes over thousands and millions of years. Non-renewable energy is power generated from such a resource.
