200 years worth of oil?
The US consumes 20.73 million barrels per day. Link
Thats 1,513,290 Million barrels needed to fullfil that 200 year promise (if the US maintains that 20.73 mbpd rate), which just so happens to be 300,000 million barrels above the current estimate of untapped oil in the world. Link
It's a shame we crack oil, or shorten the hydrocarbon chains, to make gasoline out of a product that could be used to make plastic components (think medical supplies among other cases).
On the other hand we spend so little money in research into collecting solar energy, a source of energy that is so abundant that if we focused earths share of the energy into an earthquake, it would break the earth in 2 on a daily basis. Link
