I wouldn't worry! We will never ever run out of oil!

But will leave significant known deposits like the 18 trillion barrel, Edmonton deposit, where they now lie.

As we abandon fossil fuelled anything, in favour of carbon free, nuclear power and clean silent electric vehicles.

China is set to roll a million affordable electric vehicles off her production lines this year and expand production into the foreseeable future.

And has signalled an intent to outlaw the production of conventionally powered vehicle by 2020?

Economies of scale that has made unsubsidised prices as low as $17,000.00 possible! We will have little choice, other than follow?

Other than that, we retain an ability to crack the water molecule to produce hydrogen, then combine it with vacuumed carbon to create anything fossil fuels used to provide!

From fertiliser to fuel and plastics!

Don't worry about running out of energy, just worry about replacing the moribund morons now in charge and who stand resolute and immovable, against intelligent transition!

Correction and apology. 18 trillion barrels should read, 1.8 trillion barrels. The (.) key seems to be defective?
