"… the Dutch lived (again, measured by the standard of countries without turf and inland navigation) as if their country had two floors, as if every hectare yielded a double crop: one of that which was actually grown (on the ground level) and the other a full harvest of fire-wood and horse fodder (on the imaginary first floor)."
"The situation can best be understood if one imagines that the Dutch lived as if each one of them led a double existence. In the first place they carried on with undivided attention their own professions (on the ground level) ; in the mean time everyone's alter ego seemed to perform a full job in nursing, harvesting and transporting the crops of the imaginary first floor. Compared with other countries the Republic offered its inhabitants in this way twice doubled opportunities for development, based on both the double apparent yield of its hectares and the double apparent achievement of its active population. This can explain the explosion of creative power, referred to in the introduction. Among the computed 165,000 + p.m. people we recognize those who manned ships and explored the world, who pursued commerce and science, who printed books and maps, who made arms and clocks, who painted or served other Muses, who pumped dry polders and pursued all the other activities, most of these lucrative activities at that, which helped to push the spiral of prosperity vigorously upward. But at the base of all this the sailing inland skipper with his deck-load of turf was holding the helm."
"Whilst the introduction of steam technology may have freed warships from the vagaries of wind and tides, the navy was now chained not just to coaling stations, but also to the wider infrastructure which guaranteed coal's movement to these stations around the globe. Thus, the ability to control both the source of the fuel and its movement was crucial to the mobility of British naval vessels tasked with protecting British interests worldwide, and was, therefore, central to British global power."
"…the black diamond really sways the destinies of Empires'. This importance also led to the nickname King Coal: ‘the source of [Britain's] commercial prosperity and the secret of our naval supremacy … coal is the first requisite of empire".
‘… a country may have the most powerful navy in the world, but if it be without coal it will be in the position of a man with a pipe and matches and no tobacco’.
To commit the Navy irrevocably to oil was indeed “to take arms against a sea of troubles”’. Thus, in moving the navy from coal to oil, Britain had created new problems for itself. The most obvious of these was that Britain now needed oil, and lots of it, to fuel the ships responsible for protecting its increasingly weak geopolitical situa- tion, and that oil could only be found outside of British control. Britain now faced the same issues as its rivals had with coal: that the size and technology of its navy mattered little if it could not control its fuel supply.
The hypothetical point in time when the global
production of oil reaches its maximum rate,
after which production will gradually decline.
