Even the term “fossil fuels” is an inappropriate framing of the chemicals involved since it restricts their use to burning. Consider the processes involved in their formations: organic material grew for eons millions of years ago. It then had to be buried in just the right conditions and later embedded into even further beneficial conditions. It took millions of years, high temperatures, and high pressures to go from plant material to these complex molecular forms. Then we dig them up or seep them out with fracking and further refine them. Then we burn them. Huge losses of energy all along the way. Using oil as fossil fuel is a huge waste of the energy it took to create those molecules.
