In the past they have spurred exploration and the discovery of new cheap oil sources.
Additionally, higher oil prices brought on by higher demand and lower production make these alternative oil sources financially feasible.
It might happen again, but new oil sources are found in increasingly costly places like deep water and perhaps the ecologically fragile Arctic.

Oil industry sources quoted by Reuters news agency say Iran's top oil buyers in Europe have already started reducing purchases of Iranian crude.
As oil and gas firms spend increasingly large parts of their budgets to explore and develop new sources of oil, gas and unconventional sources of hydrocarbons, upstream services firms like Halliburton are expected to reap the windfall as the exploration and production of oil become more challenging and technologically intensive.
The SOA branch said ConocoPhillips China had made little progress in checking for potential oil spill sources and preventing more spills.

Lawmakers boasted of more efficient vehicles, less dependence on foreign oil, cleaner fuel sources and punishment for oil companies that dared to engage in price gouging.
Experts are concerned that falling prices, combined with the economic downturn, will discourage oil companies from investing in new sources of oil needed to meet future demand.
Coleman said that ethanol, while not perfect, is a much better option than oil, especially the types of extreme energy sources that oil companies are going after today.
He hopes to bolster his supply with emu oil from other sources, but it's getting more expensive as demand increases.

The goal in doing so: We will reduce our reliance on foreign sources of oil to less than 50 percent by 2010 to protect our energy security.
The real goal of these groups was not to protect water along the pipeline route, but to make it impossible to develop new sources of oil in Canada.
New technology, avidly sought today, could well spur any number of alternative energy sources: oil sands, oil shale, natural gas converted to liquid, coal converted to liquid, etc.
There are vast deposits of natural gas lying offshore and throughout this country and it's a potentially important alternative to foreign oil and other energy sources as well.
