for the sake of our children's children, why are we as a [human] race not working harder to find a practical energy source less finite/precious than oil? i suspect that some chemists would say that oil is a precious resource not for mere fuel but for the manifold non-fuel-related products obtained using oil, for which there is no other useful and/or economical substitute ingredient. WP chemists, SPEAK UP!
People follow the line of least resistance. Right now hydrocarbons are plentiful enough that finding alternatives is relatively more expensive than going with the current fuel sources. When they become truly scarce alternatives will be found, or we shall perish.
When whales were hunted to near extinction, it was only then that petroleum and its derivatives (kerosine in particular) were exploited. When Col. Drake struck oil in Pennsylvania in 1859, he was not looking for fuel to make his engines go. He was looking for a source of kerosine to replace whale oil which was becoming progressively more scarce and therefore more expensive. Fuel for lighting was, at the time, the primary objective. Gasoline (or petrol, as some call it) was initially a by product of kerosine refinement. It was not until the late 1800's that gasoline became desirable to power up internal combustion engines. The demand for kerosine abated when Edison, Tesla and Westinghouse made electrical power and lighting systems a practical reality. However just as kerosine demand was going down, the gasoline powered internal combustion engine came online, and oil became the feedstock for petrol production. If electric cars had been practical we probably would not extracting as much oil since coal and natural gas can be used for powering electrical generating stations.
The bottom line: the fuel of choice is determined largely by economic factors, in particular cost of production and distribution. It has nothing to do with a sinister cabal or conspiracy. It is purely (or almost purely) a matter of money.
