Energy Unit lecture outline & graphics – Fritz StahrTues 1/21/03 - Transportation of Energy & Energy of Transportation – an intricate link- history of settlement & industry largely due to transportation and energy supplies- initial towns on rivers or by sea where ships could service cargo as water and wind onlyreal power to move goods, people- early use of hydropower, streams and falls to generate mill power, or wind in Holland- Fig 62 from Lomborg: indicates wood and hydro initial primary sources of energy until~1880s then coal, and finally oil takes over in US after ~1925, largely because oil mosttransportable and denser energy than coal- McNeill’s Coke-town cluster where it is due to ease of access to coal shipped on water(and later rail) and steel shipped out, somewhat true of Mo-town cluster as well- rail transport developed because steam engine (developed 1769) created way to takesignificant energy mobile – initially wood burning, but supplies and safety created shift tocoal (now old engines left typically burn oil)- oil generated road system after perfection of internal combustion engine ~1930’s –development driven by car/truck culture and public works- most road expansion post WWII to mid-fifties – now business and culture completelydependent on it- cities develop/die where highways go/don’t…ghost towns on major highways?- now chicken & egg problem re: which comes first, housing developments or roads – e.g.,Samamish plateau in E. King Co.- 50 M cars registered in 1954, 350M in ’89, 500M in ’00, but there is “no free road orparking” – Lovins- firmly entrenched road/car/truck systems in world – 1/7th all oil of world consumed on USroads, probably ~1/4 of all used for transport world-wide, therefor big obstacle of future ishow to change energy use for
