why are fossil fuels nonrenewable
So essentially, all fossil fuels are considered non-renewable. Fossil fuels are considered nonrenewable resources because, fossils fuels are made from the remains of dead plants or animals. It takes more than a million years for the fuels to form from the fossils.It is a long process.ossil fuels are considered non-renewable sources of energy because when they are burnt, they are finished. When the last barrel of oil has been pumped out of the ground there is no more. It is non-renewable. Similarly with coal and natural gas.
