Title: About Time


1
About Time
  • Facing the end of fossil fuels

2
Our ignorance is not so vast as our failure to
use what we know.
M. King Hubbert

Shifting Time
  • 17th century
  • Archbishop Ussher earth formed in 4004 BC
  • 18th century
  • Count Buffon 75 thousand years
  • 19th century
  • Lord Kelvin 98 million years
  • 20th century
  • 4.5 billion years

4
Big Questions
  • How long are we here for?
  • How much energy do we need?
  • How much energy do we have?
  • How quickly can we change?

5
Business as usual
  • Energy consumption is growing at ½ the rate of
    long term economic growth
  • Global economic growth rate is 4
  • Global energy growth rate is 2
  • Current global oil consumption rate is
    31GBbl/yr, 1GBbl every 12 days

Consumption at 2/year

Total consumption doubles every 35

oil this century

Changing Views IEA
  • IEA undertook its first ground up analysis of
    energy production in 2008
  • Estimates for growth of oil production trimmed
    from 120 Mbpd to 105 Mbpd
  • IEA calls for investment of 28 Trillion to
    maintain growth

10
IEA 2008 Revised Oil Forecast
11
IEA Whistleblowers
  • "The 120m figure always was nonsense but even
    today's number is much higher than can be
    justified and the IEA knows this.
  • "Many inside the organisation believe that
    maintaining oil supplies at even 90m to 95m
    barrels a day would be impossible but there are
    fears that panic could spread on the financial
    markets if the figures were brought down
    further.
  • Key oil figures were distorted by US pressure,
    says whistleblower Nov. 9, 2009, guardian.co.uk

Lloyds of London
  • Traditional fossil fuel resources face serious
    supply constraints and an oil supply crunch is
    likely in the short-to-medium term with profound
    consequences for the way in which business
    functions today.

16
Oil Executives say
  • Christophe de Margerie, head of the French oil
    giant Total, flatly declared that the "optimistic
    case" for maximum daily output was 100 million
    barrels
  • Royal Dutch Shell's CEO, Jeroen van der Veer
    "after 2015 supplies of easy-to-access oil and
    gas will no longer keep up with demand."

17
US Joint Forces say
  • By 2012, surplus oil production capacity could
    entirely disappear, and as early as 2015, the
    shortfall in output could reach nearly 10 MBD.

    Joint Futures

18
Three reasons for Peak Oil
  1. Few large fields, many small fields
  2. Increasing capital costs
  3. Declining energy return on energy investment

19
1 Dependence on giant fields
  • Over half of our oil production comes from 130
    giant, aging oil fields
  • Remainder comes from about 4500 currently active
    fields
  • As giant fields decline they will have to be
    replaced by many smaller fields
  • Exploration rates and investment will have to
    increase

21
2 Increasing capital costs
  • At up to 100 million, deepwater wells cost 10
    times more to develop than onshore wells
  • Nonconventional oil is even more expensive
  • Share of global capital allocated to oil will
    have to rise

Saudi Conventional Wells 4,000
Saudi New Development 16,000
Kashgan Giant Field 93,000
Alberta Tar Sands 143,000

3 Declining EROI
  • Conventional oil 201
  • Tar Sands 51

3 Declining EROI
24
The downward slope
  • Likely too late to start mitigation before peak
  • Rate of decline is unpredictable
  • Peak may be masked by economic recessions
  • Mitigation strategies will take decades to
    implement

25
World energy use
Fossil Fuels 85
26
Mitigation vechicle efficiency
  • Vehicle efficiency
  • Mpg standards could be doubled
  • 20 year replacement time for auto fleet
  • Efficiency offset by growth in car ownership
  • Efficiency potential is limited
  • Engines at near practical limits
  • Aerodynamics are largest problem
  • Solution is small, lighter and slower

27
Mitigation Fuel substitution
  • Coal-to-Liquids/Gas-to-liquids
  • Half of the energy content of coal consumed in
    the conversion process
  • GHG emissions effectively double
  • URC Coal reserves being revised downward
  • Additional demand would reduce them faster

28
Climate Change
  • it is feasible to keep atmospheric CO2 from
    exceeding about 450 ppm by 2100, provided that
    emissions from coal and unconventional fossil
    fuels are constrained.
  • James E Hansen, Implications of peak oil for
    atmospheric CO2 and climate

29
Climate Change
  • Peak oil will not prevent climate change
  • But IPCC worst case emission scenarios may not be
    realistic

30
Time is running out
  • We are exhausting our non-renewable energy
    resources to destroy our renewable resources
  • Within a century we will be left with neither
  • The rate at which we can adapt is likely to be
    slower than the rate of energy decline
