Take Care, Water is not a Limitless Resource
Cheap light crude oil production has already peaked and the resource will be all but gone within a decade. It is a matter of ebullient debate exactly to what extent that gap might be filled by unconventional sources of hydrocarbons, e.g. from tar-sands, ultra-heavy oil, oil shale, shale oil (they are not the same thing) and fracking in general. This spectral shadow looms, of the intermediary era that straddles then from now - dearth from plenty - a highly uncertain transitional period within which, either by design or default, we must gear-down our use of transportation, since there is no alternative technology that could be brought on-stream in time (if ever) to match the gargantuan 30 billion barrels of oil that are used by the world each year to quench its thirst for liquid fuel and essential chemical raw materials for industry.
