There are several factors that are involved in making fossil fuels:
1 raw materials (which you mentioned)
2 some breakdown of those materials (this we may be duplicating with genetic engineering of microbes which suggests there were ancient microbes that have become extinct)
3. some pressure from being buried under tons of Earth
4. long periods of time for the compounds to finally change into what we have today.
One thing that is at least suggested by the term "renewable" is that the item can be produced faster than it is made. I saw one estimate that suggested that the oil we have used in the last 150 years took more than 11 million years to accumulate over 50 million years ago. This is not the formula for a renewable resource.
In order for a resource to be renewable, it must be able to grow within a lifetime or two. Say, a tree.
Fossils fuels however take, if I am correct, millions of years to form. So yes, they CAN be made, but they are non-renewable.
That's the theory on how they are made . All the dinosaurs did not go to the middle east to die like the Tarzan movies Elephant graveyard .
They take too long to create; for something to be renewable it has to be created within one lifetime like a tree, solar power, vegetable oil, wind, etc
well...because it literally takes millions of years!
If fossil fuels are made up of woodland/marshes/dead sea creatures being crushed under the surface, surely they would be replenished very very slowly?
