High Quality Content by WIKIPEDIA articles! History of the oil shale industry started in ancient times. The modern industrial use of oil shale for oil extraction dates to the mid-19th century and started growing just before World War I because of the mass production of automobiles and trucks and the supposed shortage of gasoline for transportation needs. Between the World Wars oil shale projects were begun in several countries, but after the World War II, the oil shale industry was phased out in almost all countries because of high processing costs and the discovery of large supplies of easily-accessible crude oil. As of 2009, oil shale was commercially used in Estonia, China and Brazil, while several countries are considering to start or re-start commercial use of oil shale.
