Oh by the way, the concept of "fossil fuels" may be a totally flawed notion from the get go. Witness the photographs of Saturn's moon, Titan. There is an atmosphere of methane and oceans of hydrocarbons, that resemble oil or .... gasoline. Point being, there is no life there to fossilize and "produce" future energy reserves. I think that we are witnessing that this is just the stuff that our solar system's planets have as part of their inventory of compounds.
Ah, yes, the deep earth hydrocarbon hypothesis. The Swedish deep bore showed nothing.
"T. Gold once said, "In choosing a hypothesis, there isn't any virtue in being timid." Neither have the Swedes been timid in following Gold's lead by drilling for natural gas in the granite of central Sweden. All the experts predicted this quest would come to naught, because there are no source rocks in the area containing biological materials from which the gas could have been generated. But Gold does not believe that the methane in natural gas comes from buried organic debris. Rather, most methane is primordial and abiogenic, a legacy left deep in the earth's crust when our planet was formed.
The 72-kilometer-diameter Siljan Ring in central Sweden is generally believed to be of meteoric origin. The granite here has been shattered, perhaps to a depth of 40 kilometers. If Gold's hypothesis about the origin of methane is correct, methane might well be found seeping up through this wound in the earth's outer skin. Further, the shattered granite might prove to be a gigantic reservoir of valuable methane. The Swedes decided to drill.
After three years and the expenditure of $40 million, drilling at the Siljan Ring has been terminated. The drill penetrated to 6.8 kilometers before it got stuck. No significant methane had been found."

Yet more evidence (as if any more evidence is needed) that humans are self deluded.
