Unformatted text preview: UCSD Physics 12 A Look at the Future? Peak Oil and Beyond UCSD Physics 12 The U.S. Lower 48 Oil Production History Despite advanced technology and a desire to be independent of foreign oil, the production of oil in the U.S. peaked and moved to a state of decline. Spring 2010 2 UCSD Physics 12 Is anything being done? There is very little awareness of "Peak Oil" in this country even on Wall Street, and on Capitol Hill But the Department of Energy commissioned a study (the Hirsch Report), published Feb. 2005 that concluded: peak is inevitable a problem unlike any ever faced by the world must start mitigation decades ahead of peak options for liquid fuels replacement are limited, and mostly still fossil-fuel-derived 3 Spring 2010 UCSD Physics 12 A look at the Hirsch Report Google: peak oil go to Wikipedia link (near top of list) under "Possible Effects..." heading, see reference to Hirsch Report clicking the link for the Hirsch report main article, find summary (PDF) link near top alternatively, full report available in link at bottom Let's spend some time looking at this report... Spring 2010 4 UCSD Physics 12 So the DoE knows: who else? Roscoe Bartlett (R-MD) and Tom Udall (D-NM) have formed a Congressional Peak Oil Caucus commissioned a GAO (General Accountability Office) study on peak oil Google search: bartlett gao peak try: coverage of GAO... link GAO study concluded essentially the same thing as the Hirsch Report: we need to act now to be assured we mitigate disaster Spring 2010 5 UCSD Physics 12 GAO Report Excerpts Because development and widespread adoption of technologies to displace oil will take time and effort, an imminent peak and sharp decline in oil production could have severe consequences. Ultimately, however, the consequences of a peak and permanent decline in oil production could be even more prolonged and severe than those of past oil supply shocks. Because the decline would be neither temporary nor reversible, the effects would continue until alternative transportation technologies to displace oil became available in sufficient quantities at comparable costs. Response: practically none: NYT and Wash. Post did not run stories crickets chirping Spring 2010 6 UCSD Physics 12 Lack of Awareness Quote from Adam Cohen (www.peakoil.org): "In my personal experience working with energy companies on stock and bond offerings during the last 3 years, I never heard any energy company employee or energy investment banker use the phrase "Peak Oil." The few times I mentioned the phrase privately to bankers, the response was "What's that?" Another quote from same source, referring to the assumed "market wisdom" of Wall Street: "Put another way, how can so many smart people in suits be so wrong?" Look how long it took global warming to get on our radar screens ironic that this one could be worse, but make global warming not as bad! Spring 2010 7 UCSD Physics 12 So what are the alternatives? The Hirsch Report discusses five mitigation strategies: Increased fuel efficiency in transportation Heavy oil, tar sands Liquefication of coal Enhanced oil recovery Gas-to-Liquids (nat. gas) All fossil fuels; all needed in parallel even then, need to start 1020 years before peak Hydrogen, corn ethanol considered non-viable Spring 2010 Q 8 UCSD Physics 12 Do we even have enough coal? Recent work by Dave Rutledge at Caltech hints that we may not have as much world coal as is assumed Rutledge estimates 240 Gtoe (gigatons oil-equivalent) of coal left in the world (90 Gtoe in the U.S.) "Official" estimates are 460 Gtoe in world, 146 Gtoe in U.S. For comparison, the estimated 1 trillion bbl of oil left amounts to 140 Gtoe So coal isn't even twice as abundant as the remaining oil, if this is right The U.K. down-revised their coal estimates by 99% from 1970 to 2005: they're basically out Spring 2010 9 UCSD Physics 12 Rate Plot of Pennsylvania Anthracite Coal Recall rate plots from lecture 6 this shows perfect execution of logistic behavior courtesy D. Rutledge Spring 2010 10 UCSD Physics 12 British Coal History: Game Over courtesy D. Rutledge Spring 2010 11 UCSD Physics 12 The Tail end of British Coal courtesy D. Rutledge Spring 2010 12 UCSD Physics 12 Economic Growth and Energy Use Energy use is directly correlated with economic prosperity Spring 2010 13 UCSD Physics 12 Chicken-and-Egg Problem Is energy use just keeping pace with economic growth? Or is economic growth possible only if energy is available? related issue: indefinite growth means unbounded exponential behavior--incompatible with a world containing finite land, water, resources The world changed with the industrial revolution, and this was only possible because energy (coal) was cheap and abundant Spring 2010 14 UCSD Physics 12 U.S. Economic Growth and Energy Usage Energy usage (created from Fig. 1.1 of book) Spring 2010 15 UCSD Physics 12 What happens after world oil peaks? Worldwide oil production will inevitably peak the speed with which we can extract oil from the ground is limited, and will diminish the U.S. experience (plus 33 of 48 major oil-producing countries that are in decline) is a good example What happens then? gas prices go way up (even more!) transportation becomes expensive all sectors of our economy impacted all consumer goods, agriculture, etc. depend heavily on liquid petroleum Spring 2010 16 UCSD Physics 12 What can/should you do? Understand that we don't know what the future holds I may be over-reacting to the potential threat Raise your awareness of energy issues Make life plans that allow flexibility have a plan B, or pick a direction that will be valuable in any eventuality Adjust yourself to a world with less stuff/goodies less jarring if hard times hit, and easy to please if hard times don't hit Lower your own demand: best way to buy time for problem Spring 2010 Q 17 UCSD Physics 12 Announcements/Assignments HW #2 due today (4/16) Quiz #2 expires midnight, 4/16 HW #3 will be posted shortly Spring 2010 18 ...
