Title: Peak oil
1Peak oil
Transition Training 2007
2 Peak oil- What is it?
- Peak oil is the point at which we can no longer
increase the amount of crude oil we extract and
globally petroleum production goes into
irreversible decline. - This typically happens when an oil province has
extracted roughly ½ of all the oil that is ever
going to be extracted from that province - it is
not when the oil runs out. - This slide illustrates why the sum total of a
collection of oil fields in a region when added
together creates a peak at about the half way
point in production
3Typical Oil Well
Transition Training 2007
4Peak oil- What is it? How an oil well works
- Initially the oil is under pressure and when you
drill into the oil bearing rock, the pressure
drives the oil out of the stone and upwards to
the surface. - You can drill several wells into the same field,
increasing output from that field - After a time the pressure begins to fall so
production falls. To get the last recoverable oil
out water or gas is pumped into the field

6Peak oil- What is it? Oil field production
- These two large oil fields illustrate the basic
dynamics of oil production - A steep initial increase, a production plateau
and then a slow but irreversible decline. - Once the peak is past there are many techniques
and technologies that can brought to maximise the
declining output, but it is a losing battle and
production will never return to it former levels.

8Peak oil What is it? Oil production follows
discovery
- Oil production peak follows oil discovery peak,
usually 25-40 years later. - This is the time it takes to get production going
after the initial finding. - In country after country and oil province after
oil province the pattern is broadly the same
four examples are shown of countries that have
peaked. - Globally we are now discovering 1 barrel of oil
for every 5 or 6 that we use.
9UK production profile

10When will it happen? UK Oil production profile
- This is the pattern in the UK, showing oil
production from the North Sea. - Each coloured band shows a different oil field
- Britains production peaked in about 2000 and is
now in steep decline. - Britains oil and gas will be virtually gone in
15 years.
11Global oil discovery and production
Transition Training 2007
12When will it happen? Global oil discovery,
production, and demand
- To produce oil you first have to discover it.
World discovery peaked in the late 1960s and has
been falling ever since, and despite rapidly
improving and sophisticated, technology, there
is no prospect of it ever increasing. - At the same time production has been rapidly
rising. - Demand is projected to go on rising, (with
production failing to keep up), especially in
rapidly industrialising countries like China and
India, and is leading to rapidly rising oil
prices. -
13When is the global oil peak?
Transition Training 2007
14When will it happen? When will global oil
production peak?
- The argument is when will we peak, not whether.
This graph shows various predictions of the
global oil peak. They cluster around 2010, with a
few optimistic analysts, predicting a peak many
years in the future. - Dr James R. Schlesinger, former US Energy
Secretarystated in 2007, You (peak oilists) are
no longer the beleaguered small minority of
voices crying in the wilderness. You are now main
stream. - The predictions are from government bodies like
the International Energy Agency, oil companies
like BP, and independent researchers like Chris
Skrebowski. -

16When will it happen?Of the 98 producers 64
countries have already peaked
- There are 98 countries in the word that produce
oil, some large some small. - The countries in red are the countries that are
now post peak. - Their oil production is now in decline and
nothing they can do will ever reverse that. - Of 98 producers 64 have already peaked. Anyone
who tries to tell you that peak oil is a myth
should look at one of these countries- not one
has ever failed to follow the Hubberts peak
and then decline
17Exports from oil producers
Transition Training 2007
18When will it happen? Exports from oil exporting
nations
- Oil exporting nations are using their oil for
their own internal consumption at an ever
increasing rate. - Oil is often very cheap, like in Saudi Arabia,
30p per gallon, so there is no incentive to
conserve. - As their economies are booming, and their
population is also growing rapidly, this means
they have less oil to export. - Oil export peaked in 2005, and after a short
plateau, is declining rapidly. This is very bad
news for countries like the USA which need to
import 16 million barrels of oil a day. -
198020 rule
- The worlds giant oilfields are in steep decline
Transition Training 2007
20When will it happen?8020 rule decline of the
giant oil fields
- The 8020 rule is that 80 of your result comes
from the first 20 of your effort with
diminishing returns after that - In oil terms we find the easy to find and produce
oil first - the largest oil fields. 50 of global
oil is produced by the 120 largest oil fields in
the world (out of over 4000 fields) - This graph shows that discovery of giant oil
fields peaked in the late 1960s. Now we find
very few giant (greater than 1 billion barrels)
oil fields, and that rate of discovery is
declining.
21WHERE WE GET OUR ENERGY
Source ExxonMobile web site
22Why is oil so important?
It is frightening how dependent we are on fossil
fuels. We have only begun the move away from
fossil fuel energy. Even if we were to double
the amount of energy we get from renewables, and
then double it, and then double again, which
would be a heroic achievement, it would still
only create 3 of energy requirements.
23If peak oil was imminent, what would be the
Canary in the Coal mine?
24When will it happen?
- Light sweet crude peaks first.
- The worlds largest oil fields peak and decline
- Countries start to decline.
- Oil price increases rapidly, and then maybe
crashes, erratic behaviour. - Exports from oil producers peaks
- Oil producer countries take control of their
resources. - .......all this has happened, and has
accelerated, in the last 5 years
25Why is oil so important? How many men does it
take to push a car?
Transition Training 2007
26Why is it so important? The phenomenal energy in
petrol
- A tank of petrol contains 8,000 human hours work!
- If you worked for 8 hrs/day, 52 weeks a year, 7
days a week that equates to about 3 years work. - Most of us take for granted the amount of energy
we have at our disposal instantly, everyday. No
human society had anything near the amount of
energy before the discovery of fossil fuels.
27What do we use oil for?
Transition Training 2007
28Why is oil so important?What do we use oil for?
- Our entire way of life, and a bewildering array
products are reliant on oil. - Transport is only the beginning of our oil use.
- Many products are derived from, or use oil or gas
as their raw material. Plastics, synthetic
fibres, drugs, laminates, paints, ink the list
is endless - The so called Green revolution , modern
agriculture depends on oil. Fertilisers and
pesticides are made from oil and natural gas,
tractors and machinery use it, irrigation
requires huge amounts of energy and this is
before food miles, processing, and storing,
cooking, and packaging and retailing are taken
into account. - Industry and even the service sector use huge
amounts of energy. -
29No country has yet decoupled economic growth from
energy use
Transition Training 2007
30Why is oil so important?
- Economic growth requires growth in our energy
supply. - We have an economic system that is dependent on
growth. - Therefore we are dependent on increasing supplies
of energy. - All forecasts of economic growth also show rising
energy demand. - When peak oil arrives we will have less total
energy so economic growth will slow and probably
decline, perhaps permanently
31The carbon cycle
1
Transition Training 2007
32The active carbon cycle
- The carbon dioxide cycle is a natural one ,and
one that has been in dynamic balance and
undergone many fluctuations and cycles over
millions of years. - There is a balance between the seas and the land
and the atmosphere. Carbon is locked up in the
seas in plankton and other marine life, and
dissolved in the water. Carbon is also locked up
in plant matter on the earth (active carbon
cycle), and in fossil deposits (inactive carbon
cycle) of oil, natural gas, and coal. - The destabilising factor in the carbon cycle is
that we have taken the locked up (inactive)
carbon from fossil fuels and put that carbon in
the atmosphere. The land and the sea carbon sinks
are unable to absorb this excess carbon.
33What is climate change?
2
Transition Training 2007
34Define Climate Change The term "climate change"
is sometimes used to refer to all forms of
climatic inconsistency, but because the Earth's
climate is never static, the term is more
properly used to imply a significant change from
one climatic condition to another.
What is causing Climate change or Global
Warming? Rising human made CO2 concentrations in
the atmosphere.
It this a theory? Yes
Why? Because it is trying to establish two cause
and effects. Firstly that CO2 is the cause of
global warming and secondly that humans are
causing it through the burning of fossil fuels.
35Is it proven?
3
Transition Training 2007
36- Have both cause and effects been proven? Is
the earth warming, and are humans causing it? -
- Main Point
- Yes, as much as a scientific theory can be
proven. It It has been confirmed by the
International Panel for Climate Change is a
worldwide group of scientists who have reviewed
all available scientific research. - Detail
- The 4th IPCC report published in 2007 states,
- 1-Warming of the climate system is unequivocal.
- 2-Most of the observed increase in globally
averaged temperatures since the mid-20th century
is very likely (confidence level gt90) due to the
observed increase in human greenhouse gas
concentrations. - This is scientific speak for yes!
- This United Nations study, which was just awarded
the 2007 Nobel peace prize, was the most
comprehensive study of peer reviewed climate
research ever undertaken, and one of the most
comprehensive studies of any scientific question
ever. Its conclusions are that there is no more
debate, the science is clear. The only question
is how fast can we act to create real reductions
in atmospheric CO2.
37What are the main problems with out of control
CC?

Transition Training 2007
38What are the main problems with out of control CC?
- Main Points
- Severe one in a hundred year weather events
becoming common - Sea level rises, leading to increasing land loss
and cc refugees - Species loss
- Additional Points
- Increased droughts/desertification. This slide is
of the Australian Murray River system, which has
faced an extreme multi year drought. The
government has had to take the decision to
allocate whatever water there is to the cities
rather than allow farmers to irrigate their
crops. This has lead to a decrease in the
Australian wheat harvest of 35 this year.
Australia is one of the bread baskets of the
world. - Increased floods- like this year in the UK.
- Acidic seas
- Species loss due to temperature zones migrating _at_
the rate of 2km/yr. This will accelerate species
loss due to habitat loss, as many species of
plants and animals will be unable to migrate with
the temperature. We face a potential of 50 or
more loss of life on earth. We are depended on
the web of life for our survival.

40The natural carbon cycle and human effects
- Main points
- This shows the ice core data measuring
atmospheric CO2 concentrations over the last
60,000 years. As you can see CO2 levels have
risen and fallen. To keep the climate from
warming more than 2 degrees C we would have to
keep CO2 concentration to below 450ppm - They are currently at 380ppm without counting the
other GHG which are Methane, nitrous oxide, CFCs. - Additional Points
- The last ice age ended 20,000 years ago and lead
to a rise in CO2, and if we went back a few
100,000 years we would see this pattern of rise
and fall. What happens next (in red) shows the
result of a new agricultural system, and human
population increase, and then the green shows the
beginning of the industrial era and the burning
of fossil fuels. The orange is the 20th 21st
century.
41The need for an urgent response
6
Transition Training 2007
42- The need for an urgent response
- Once global temperatures rise to certain levels
positive feedback loops will cause further
releases of greenhouse gases, leading to runaway
climate change - On the best evidence we need to keep temperature
rises to less than 2 C. - Emissions already made have not yet had their
full impact so we are perilously close to
reaching this even if we reduce emissions
dramatically now. - Positive Feedback loops
- For example if the arctic tundra melts it will
emit so much methane, a powerful green house gas,
that it will dwarf human CO2 emissions.
43Responses to Peak Oil Climate Change

-
- PEAK OIL
- Burn everything!
- relaxed drilling regulations
- biofuels
- tar sands and non-conventional oils
- Resource nationalism
- Resource Wars
- CLIMATE CHANGE
- Climate engineering
- Carbon capture and storage
- International emissions trading
- Climate adaptation
- Nuclear power
- P O C C
- Systems Re-think
- Planned Relocalisation
- Energy Descent Pathways
- Local Resilience
44Response to PO and CC
- Looking at peak oil alone you look for
replacements tar sands, remote fields such as
the antarctic, bio fuels, coal to liquids. - If we dont reduce oil dependency in rich
countries there will inevitably be either climate
disaster from replacements or resource wars. - Looking at climate change alone you may look for
energy intensive solutions to mitigate climate
change, including nuclear. - When PO and CC are taken together you have to
redesign the system a low energy, re-localised
and resilient system is the only viable future.
