DESCRIPTION
The 20th century was an era of cheap and abundant resources. Global energy supplies expanded dramatically. But in the early decades of the 21st century, we have already entered an era of scarce and expensive resources. In fact, in this century we may even see a contraction of global energy supplies, particularly of oil. We are perched on the verge of a global energy crisis, although very few people are aware of it, including energy experts.

Is climate change the only problem with fossil fuels?
Oil spills highlight the downside of the fossil fuel based economy
We’ve forgotten about the biggest problem:fossil fuels are FINITE

- Saudi saying
To understand our present predicament, we need to understand the special qualities of fossil fuels
• the release of enormous amounts of cheap energy from fossil fuels enabled the growth of industry, population, consumption and technological innovation
• Oil, coal and natural gas were produced by natural processes over millions of years
• they are FAR more concentrated forms of energy than the sources previously available to humanity (e.g. food crops, human & animal muscles, windmills, etc.)
Fossil fuels made modern industrial society possible
• This abundant energy available to drive production processes enabled increased extraction rates of other natural resources
– e.g. chainsaws, trawlers, etc. • Modern farming machinery
powered by fossil fuels made it possible for small number of farmers to feed large populations
– this in turn enabled massive urbanization
• Modern chemistry (largely based on organic compounds derived from fossil fuels) gave rise to modern pharmaceuticals
– facilitated longer lifespans & growing populations
Human vs. machine power
150 watts
Human vs. machine power
100 hp engine 2000 people
Imagine pushing your car 20-30 miles (32-48 km)
The energy slaves of modern man
• if we add up the power of the machines running on fossil fuels that we rely on to light and heat our homes, transport us and keep up our lifestyles and compare that to the amount of power generated by the human body:
• the average American has the equivalent of over 150 energy slaves working for them 24/7
• a middle class person today has an unimaginable standard of living compared to previous periods, largely due to fossil fuels
Oil – the master resource & most important commodity
• Oil is the lifeline of the global economy
• Our primary transportation fuel
(94% of transport is powered by oil)
– gasoline for cars– diesel fuel for trucks &
buses– jet fuel for airplanes– bunker fuel for ships
• Cheap oil has made globalization possible
• Oil is the raw material for a vast array of industrial products
13
Oil is everywhere
Oil is everywhere
Oil – an ideal fuel & raw material
• cheap & abundant (at least until recently)
• energy dense
• easily transportable
• capable of being refined into different fuels (e.g., gasoline, kerosene, diesel, bunker fuel, etc.)
• suitable for a variety of uses, including transportation, heating, production of agricultural chemicals and many many other materials
World’s first oil wellPennsylvania, USA 1859
Global oil consumption
• since 1859, the world has consumed about 1 trillion barrels of oil
• we consume about 85 million barrels a day
• over 30 billion barrels a year
• at least 1 trillion barrels of economically recoverable oil left in the ground, probably more
• so what’s the problem???
It’s not about running out
• the global economy depends upon cheap and abundant energy
• in the 20th century, energy was cheap and abundant, but that era has ended
• we are now in the era of scarce and expensive energy which is increasingly difficult to extract
• that is going to change everything

What is peak oil?
"The term Peak Oil refers to the maximum rate of the production of oil in
any area under consideration, recognizing that it is a finite natural
resource, subject to depletion."
- Colin Campbell
The US Oil Production Story
M. King Hubbert: Energy Visionary
• Fields peak when ½ the oil has been extracted
• There is a time lag of about 25-40 years between an oil field’s initial development and that field’s peak production

Why is the timing of peak oil so uncertain?
• if valid data were available in the public domain, determining the date of peak oil and the subsequent rate of decline would be a simple matter
• however, valid data is not publicly available
– instead, there is a maze of conflicting information
– OPEC countries’ reserve data is closely guarded
– oil companies are afraid of their share prices declining should their actual reserve data become public
– so experts are left to piece together the incomplete and often conflicting data
• Kuwait added 50% in 1985 to increase its OPEC quota, which was based partly on reserves; no new discoveries had been made
• Venezuela doubled its reserves in 1987 by the inclusion of large deposits of heavy oil that had been known for years
• Other OPEC countries responded with huge increases
• Note how the numbers have changed little since despite production
OPEC’s oil reserves are inflated

Discoveries of oil
• In order to produce oil, one first has to discover it; this is an often overlooked fact
• Most of our current oil production comes from fields discovered in the 1960s & 1970s
• Oil discoveries peaked in 1960s
• We now consume 4 barrels of oil for every 1 we discover
• Declines in oil discoveries eventually must translate into declines in production
Types of Oil
• Conventional Oil: petroleum found in liquid form, flowing naturally or capable of being pumped at reservoir conditions without further processing or dilution.
• Unconventional Oil: heavy oil, shale oil, tar sands (bitumen) are considered to be unconventional oil resources. These compounds have a high viscosity, flow very slowly (if at all) and require processing or dilution to be produced through a well bore.
• Natural Gas Liquids (NGLs) are those portions of the hydrocarbon resource that exist in gaseous phase when in natural underground reservoir conditions, but are in a liquid phase at surface conditions.
• Conventional oil provides most of the oil produced today, and about
95% of all oil that has been produced so far. – it is the most important form of oil and will continue to dominate
supplies for some time
Source: Hirsch et al 2010: 53
Unconventional oil: will it solve the supply problem?
• Canadian tar sands– estimated up to 1.7 trillion barrels– current production: 1.5 million bpd– projected: 3 million bpd by 2020– processing requires huge amounts
of water & energy– produces giant lakes of oily water– CO2 emissions higher than
conventional oil production
• Venezuelan heavy oil– estimated 500 billion barrels of
recoverable reserves– perhaps the largest source of
untapped petroleum on the planet– converting this heavy oil into useable
petroleum requires vast amounts of energy and money

Dr. Fatih Birol, Chief Economist, IEA
• After a detailed survey of over 800 oil fields, the IEA revised its estimates of oil depletion rates upwards from 3.7% to 6.8%
• “When we look at the oil markets, the news is not very bright. We think that crude oil production has already peaked in 2006.”
• “The existing fields are declining sharply, in the North Sea, in the United States, in the Gulf of Mexico. Just to stay where we are today, we have to find 4 new Saudi Arabias. This is a tall order.”
The Hirsch Report: a seminal study on peak oil
• conclusions:
– Waiting until world oil production peaks before taking action leaves the world with a significant liquid fuel deficit for more than two decades
– Initiating a mitigation crash program 10 years before the peak leaves a liquid fuels shortfall roughly a decade after the peak
– Initiating a crash mitigation program 20 years before peaking appears to offer the possibility of avoiding a world liquid fuels shortfall
Why will the transition be so time consuming?
• energy transitions are inherently slow and large scale
• there are no alternative energy sources that are currently competitive with oil in the transportation sector
• any transition to more fuel efficient vehicles will require decades and trillions of dollars
– existing capital stock can only be replaced gradually
– would normally require 25-30 years to replace
– more energy efficient vehicles equipment can only be gradually phased in as new capital stock replaces existing stock
The Hirsch Report: conclusions
• “Oil peaking will create a severe liquid fuels problem for the transportation sector”
• “Peaking will result in dramatically higher oil prices, which will cause protracted economic hardship in the United States and the world.”
• “In the developed nations, the problems will be especially serious. In the developing nations peaking problems have the potential to be much worse.”
• “Intervention by governments will be required, because the economic and social implications of oil peaking would otherwise be chaotic.”
Geopolitics: the lessons of previous oil shocks
• in 1973, Arab members of OPEC imposed an oil embargo on the U.S. and Western European countries in retaliation for their support to Israel in the Yom Kippur War
– quadrupling of world oil prices– long lines at the gas pumps– U.S. economy was severely affected– showed that the economic well being of developed countries
was dependent upon a steady flow of cheap oil
• in 1979, the Iranian revolution led to a steep decline in Iran’s oil exports
– worldwide oil shortages ensued– world oil prices spiked– signified that internal conflict in an oil exporting country could
significantly affect global oil supplies and prices
• these crises were caused by political events, not by absolute declines in oil supplies
• Iran’s oil production & exports – produces 4.2 million barrels
a day– exported 2.2 million barrels
a day before sanctions
• 17 million barrels of oil a day pass through the Strait of Hormuz
• if military conflict were to break out with Iran, or if Iran were to somehow block the Strait, would be catastrophic for oil supplies
Iran: potential trigger to significantly higher oil prices?
Converging trends: why time is not on our side
• global oil production is flat while demand is rising, especially in the developing world
• due to steep decline rates in existing oil wells, producers are hard pressed simply to
maintain current production rates
• oil discoveries peaked in the 1960s and have been declining ever since
• oil reserves have been inflated for political reasons
• consumption is rising steadily in key oil producing nations, which will eventually lead to
declines in exports
• we’ve used up most of the easy oil; what remains is tough oil
• unconventional sources are unlikely to resolve the supply situation due to their low net
energy and serious environmental problems
• there are no alternative energy sources that are competitive with oil in the transportation
sector
• political instability in the Middle East is pushing high oil prices up further
• prices could skyrocket if hostilities break out with Iran
What are the alternatives?
• Shale gas / oil • Gas to liquids• Coal to liquids• Biofuels • Hydrogen • Other renewables• Electrified
transport• Conservation
No easy answers!
Can the current form of globalization be maintained in an era of increasingly scarce and expensive oil?
How will the airline industry fare in a tough oil world?
Modern agriculture: using land to turn fossil fuels into food
Each calorie of food requires 7-10 calories of fossil fuels to get to one’s plate
• industrial agriculture as currently practiced is unlikely to be viable in a post-peak oil world
• this implies major changes in the way we produce, transport and market food
• it could very likely mean a larger proportion of the population will need to be engaged in farming, the opposite of current trends
• agriculture may have to become much more localized than it is now
What is the future of modern agriculture?
Can present / projected population levels be sustained?
Source: Joint Operations Environment Report 2010 (based upon UN Population Reference Bureau)
Will the competition for resources lead to military conflict?
What can you expect?
– high gasoline prices are here to stay – get used to it!
– higher food prices
– rising inflation
– recession (past oil shocks have caused recessions)
– sectors which are sensitive to oil prices (e.g. airlines, trucking, agriculture, etc) will be hit hard
– air ticket prices are likely to be much higher in the near future
– the world economy will be hit hard, and all nations will be affected
Implications of the Coming Energy Crisis for China
China & Oil
• China was a net oil exporter until 1992
• China became a net oil importer in 1993
• China’s oil import rate surpassed 50% in 2009; estimated to be 56% today
• In 2010, China accounted for 10.6% of global oil consumption
• 9 million barrels per day or 428 million tons annually
• Fuel prices in China are controlled by NDRC
• NDRC raised fuel prices for the 2nd time this year by more than 6% to reflect int’l crude oil price hikes

Conclusions: • China’s oil consumption cannot continue to grow at present
rates; there is simply not enough oil out there• China is very vulnerable to oil shocks, and increasingly so
as imports rise (esp. in industry & transport sectors)• China has no choice but to electrify its transport system as
the country’s vehicle stock expands• In the global competition for resources, China is WAY ahead
• the US consumes 19 million barrels of oil per day (2x China), 21% of global consumption
• US is the world’s #1 oil importer at about 10 million barrels of oil a day
• the transport sector accounts for 71% of US oil consumption
• Overall, the US is extremely vulnerable to supply shocks, despite projected increases in domestic production

The age of cheap and abundant resources is over
• Americans – and the world – haven’t grasped this yet
• Not just oil:– water– many metals & minerals– uranium– grain production (per
capita)– wild fisheries
• We are in a different era now, which calls for different approaches
We’re in for a bumpy ride:The next 20 years will not be anything like the last 20 years
Conclusions
Due to geological and geopolitical reasons, a global energy crisis centering on liquid fuels is likely in the near future
• we need to rapidly put in place a sustainable energy infrastructure to replace the existing oil infrastructure
• we need to do so NOW, not simply because of climate change (the usual justification), but also because of the global energy supply picture
• a smooth and seamless transition to an alternative energy regime is no longer possible because we have far waited too long
• we must get actively involved in the conversation about alternative energy sources, or it will be imposed upon us
Thank you!

The Shale Gas Revolution
• IEA is now referring to a ‘golden age of gas’
• ‘hydraulic fracturing’ or just ‘fracking’
• Horizontal drilling combined with fracking has dramatically changed the natural gas landscape
• EIA estimates US has 860 tn cubic feet of ‘technically recoverable’ reserves
• China: 1,275 tn cubic feet
• Global shale gas reserves of 6,600 tn cubic feet; roughly equal to today’s current reserves
Shale Gas: Boon or Bane?
• Requires vast amounts of water: 2m-4m gallons per well + 15,000-60,000 gallons of chemicals
• Not suitable for arid regions
• Sand mining
• Risk of groundwater contamination by toxic chemicals and methane
• Risk of earthquakes
• Generated a popular backlash in US & Europe
• France has banned it; NY State temporarily banned it, now lifted
• At best, shale gas should be treated as a bridge fuel

German military think tank report on peak oil
• Conclusions of the report by the Bundeswehr Transformation Center (leaked to the media in August 2010):
– In the near term, rising oil prices will lead to lower consumption and economic output (e.g., recession or worse)
– Increasing transportation costs will lead to lower trade volumes, lower incomes for many and unaffordable food for some
– Pressure will increase on gov’t budgets as they struggle to keep populations fed, deal with mass unemployment and try to invest in sustainable forms of energy
– “In the medium term, the global economic system and every market oriented national economy would collapse.”
Causes & consequences of the oil shock of 2007-08
• “Whereas historical oil price shocks were primarily caused by physical disruptions of supply, the price run-up of 2007-08 was caused by strong demand confronting stagnating world production.”
• “The experience of 2007-08 should thus be added to the list of recessions to which oil prices appear to have made a material contribution.”
