Are there countries who tried to save oil by inventing ways to prevent its scarcity such as using alternative oil or gasoline? Can anyone name those countries? I salute them for saving our world.

Brazil uses bioethanol from sugar cane, in the US it's used from corn but I wouldn't give credit to them as doing anything beneficial. It's an alternative but not a solution.

The Diesel Tree: Grow Your Own Oil

Copaifera langsdorfii
Oddly this is not news. The Center for New Crops & Plant Products, at Purdue University reports that it was first reported to the western world as far back as 1625. They observe reports from 1979 saying "Natives ... drill a 5 centimeter hole into the 1-meter thick trunk and put a bung into it. Every 6 months or so, they remove the bung and collect 15 to 20 liters of the hydrocarbon." The UN's Food and Agriculture Organisation noted in a paper at the Eleventh world forestry congress back in 1997 on the topic of tree oil for cars that "... the potential of other alternatives such as the Amazon Copaifera langsdorfii need to be investigated."
It produces a large amount of terpene hydrocarbons in its wood and leaves. One tree can produce 30 to 53 liters of hydrocarbons per year, en masse producing 10,000 - 12,000 litres/hectare/year which is incredibly high. The oil is collected by tree tapping. The main compound in the oil is copaiba, an oleoresin which is useful in the production of oil products such as lacquers and can be used as biodiesel. The tree is also the main source of copaene, another terpene.

So Florida is new KSA?
