Just before prices fell from their highs at over $110 per barrel in the middle of 2014, the common wisdom among the same experts was that prices were expected to stay high for a while.
 But almost three years later, they are still in a relatively low range of the upper $40s to the lower $50s per barrel.
 They may remain low for a considerable time as shale producers in the US have adjusted to this environment. Even though prices could rally in the short to medium term, in the long run (by that I mean as early as the late-2020s), oil will start losing its lustre.
 This last age of oil will come as the transportation revolution displaces oil’s major role as a fuel for transportation, especially in motor vehicles.
