Why are fossil fuels considered to be non-renewable?
Fossil fuels like coal and lignite are considered to be non-renewable because superficially looking people are not aware of the current coal and lignite forming processes in the Earths crust. More importantly, these fuels are called non-renewable because their renewability rate is so small (i.e. the time period required for their formation so long) that their renewability is irrelevant for society from an economic, cultural, and even biological point of view. Evolution shows that the average life span of a species (like Homo sapiens) is 3 million years, that of a genus 15 million years. The renewability of Coal with a rate of many millions of years therefore has no relevance for humankind. The sense of renewability lies in the actual renewal and therefore renewable resources should not be exploited at a higher rate than their regeneration. The volumes of old coal currently being burned are many orders of magnitude larger than the volumes of new coal currently being formed. Such fuels m
