The majority of oil is refined for chemicals needed for industrial manufacture. Until the internal combustion engine came along, Petroleum was just a waste product left over from distillations.
If all vehicles stopped using oil based fuels, they'd have the problem of what to do with Petroleum waste again.
As usual the niave Greens don't actually have nuch of a clue about the real facts about oil. If we have no cars, they reason, we won't need to drill for oil.
VERY BIG WRONG!!
We will still need oil for all the other things we use it for, such as lubricants, plastics, pharmaceuticals, chemicals, metlurgicals, etc. We don't drill for oil soley for fuel reasons as this is just a byproduct.
Geoligust estimate, at current consumption, we have enough oil reserves for just over 500 years. And that is before we start poking around under the deep oceans.
The Greens seems to always mistake the the statement that Dubai will run out of oil in the next 50 years, as the World will run out of oil in the next 50 years. Then the propoganda about "How we need to push for alternative power sources and stop using cars", etc. based around this mistaken premise.
I think that because the public could see that they were wrong over this caused the latest CO2 scam. Unfortunately, the figures don't add up here either and the public is skeptical once again.
I'm for some Green issues such as landfill, chemical waste, recycling, polution, etc. but the CO2 thing is a crock, investigate the way the theory contradicts science facts and laws of Physics, history, etc.
Even if all the vehicles were not fossil fuel powered, we'd still need oil for lubricants for the vehicles.
Before oil, we used to depend on Whale oil for lubricants, fuel, chemicals, etc. and look what damage that did to the envioronment!!
