Magnitude of energy derived from oil; A gallon of gasoline will move a medium size car 20 miles. Go out and find a level stretch of road and push your car 20 miles. When you get done, we will talk about renewable energy.
A loaded eighteen wheeler can go a mile on something between a pint and a quart of diesel. Give the driver a hand truck, and it'll take him something like five hundred hours.
In addition he argues that prior to finding fossil fuels, we lived paycheck to paycheck of our energy quota. Finding fossil fuels, was like winning the Lotto, and there is a good possibility we are nearing the end of energy Lotto.
Underlying all the grand and sweeping fantasies of endless economic growth powered somehow by lukewarm sunlight and inconstant wind, I’ve come to think, lies the simple fact that the human mind never quite got around to evolving the capacity to think in terms of the huge amounts of energy our species currently, and briefly, has at its disposal. It’s one thing to point out that a planeload of tourists flying from Los Angeles to Cairo to see the Great Pyramid, back when political conditions in Egypt allowed for that, used more energy in that one flight than it took to build the Great Pyramid in the first place. It’s quite another to understand exactly what that means – to get some sense of the effort it took for gangs of laborers to haul all those blocks of stone from the quarries to the Nile, load them on boats, then haul them up from the Nile’s edge east of Giza and get them into place in the slowly rising mass of the Pyramid, and then to equate all that effort with the fantastic outpouring of force that flows through the turbines of a modern jet engine and keeps an airliner poised in the thin air 40,000 feet above the ground for the long flight from LA to Cairo.
Apply this to energy and you’ve basically got the history of the modern world. Until our species broke into the Earth’s store of fossil fuels and started going through it like a lottery winner on a spree, we lived from paycheck to paycheck on the incoming flows from the sun, and we got fairly clever at it. Growing food crops, raising livestock, building windmills and waterwheels, designing houses to soak up heat from the sun in winter and shed it in the summer, and a good many other ingenious tricks gave us the annual paycheck of energy we used to support ourselves and cover the costs of such luxury goods as art, literature, philosophy, science, and the occasional Great Pyramid.With the transformation of coal from ugly black rock to energy resource over the course of the eighteenth century, that changed radically. Simply put, our species won the lottery, and it wasn’t a paltry little million-dollar prize, either – it was the great-grandmother of all jackpots, unimaginably vast enough that for most of three hundred years, the major constraint on how fast we used fossil fuels was the struggle to figure out enough clever ways to use it all. What nobody noticed at the time, or for a long time thereafter, was that we’d switched from a flow to a fund, and the faster our fossil fuel use accelerated, the faster the bank balance depleted
