> Unless of course the abiogenesis theory is correct, in which case oil and at least some natural gas are also dead-star fuel. I don't see how whether abiogenesis theory is correct or not matters here. The energy trapped in oil and natural gas is not from "life" but from the sun. Of course it wouldn't have accumulated without life, but that is not the source of the energy.

Abiogenesis means oil and gas are primordial matter. Trapped sun energy in the form of biomass is biogenesis.

  Ah thank you for the clarification. I was not aware that it was used in that meaning too. The only meaning I did know is in the context of origin of life.
