A coal mine in Wyoming, United States. Coal, produced over millions of years, is a finite and non-renewable resource on a human time scale.. A non-renewable resource (also called a finite resource) is a natural resource that cannot be readily replaced by natural means at a pace quick enough to keep up with consumption. [1]
Renewable and wasted carbon can provide a path to low-cost, clean-burning, and low-soot-producing jet fuel. Research shows an opportunity to produce fuel in which aromatics are initially diluted with the addition of renewable isoalkanes, aromatics are later fully replaced with cycloalkanes, and finally high-performance molecules that provide ...

Energy independence is being attempted by large or resource-rich and economically-strong countries like the United States, [12] [13] Russia, [14] China [15] [16] and the Near [17] and Middle East, [18] [19] but it is so far an idealized status that at present can be only approximated by non-sustainable exploitation of a country's (non-renewable ...

Renewable resources are available each year, unlike non-renewable resources, which are eventually depleted. A simple comparison is a coal mine and a forest. While the forest could be depleted, if it is managed it represents a continuous supply of energy, vs. the coal mine, which once has been exhausted is gone.
