2Overview of the challenge
- Our industrial economy was built on cheap energy
- Transportation, communications, trade,
agriculture, heating/cooling, consumer lifestyle
all depend on energy - Energy demand is rising rapidly and the supply is
shrinking - Adaptation will be extremely expensive
- Western material civilization is unsustainable
3Energy demand 2005-2030
- Energy needs will grow 50 by 2030
- 45 of this in India and China
- Coal demand will increase 73, mostly in India
and China - CO2 emissions will rise 57 (2/3 from US, China,
India, Russia)? - IEA/OECD World Energy Outlook 2007
4Developing countries
- Two thirds of future growth in energy demand is
expected to come from developing countries where
at least 1.6 billion people are without access to
electricity in their homes. - Over half of people in developing countries still
rely on biofuel, including wood, dung and
agricultural wastes, for cooking and heating,
most of which is burnt indoors. - Between 10 per cent and 20 per cent of the fuel
used in households on biomass stoves is not fully
burnt, triggering a wide range of harmful
air-borne pollutants. - Globally, indoor air pollution of fine particles
from fuels like charcoal is ranked in the top ten
causes of mortality, causing up to 2.4 million
premature deaths a year from respiratory problems
and heart attacks. - In homes burning biomass, particle levels can be
between 300 to 3,000 microgrammes per cubic metre
( EU guideline 40 µg/m3). - GEO Year Book 2006 http//www.unep.org/geo/yearboo

5The Science of Energy
- Second Law of Thermodynamics entropy
- All resources are limited on a finite planet
- Human civilization has reached planetary limits
- Growth cannot continue indefinitely
- The human population is expected (barring
surprises war, famine, pestilence) to reach 9
billion in mid-century and then decline - Planetary carrying capacity depends on numbers
and standard of living
6The end of the fossil fuel era
- Consumption continues to grow at 1.1/yr
- At present consumption rates, conventional
reserves of oil will last 40 years, gas 60 years
and coal 165-285 years - Published reserves can increase through new
discoveries (declining) and new extraction
technologies, but costs tripled 1999-2006 - Other constraints are investment cost,
environmental impact and insecurity in supply - Massive investment in present infrastructure
creates great resistance to change
7Growth in oil use
- World 1.1/year
- OECD 1.3
- World less economies in transition 2.1
- Latin America 2.8
- India 5.4
- China 7.5 energy demand will double by 2020
- From 2001-2020, world oil consumption will rise
56, with OPEC production doubling - Non-OPEC production has already peaked
- Oil provides 40 of world's primary energy
8How much oil?
- (reserve estimates are highly controversial)?
- Ultimate recoverable reserve 2000 Bb
- Cumulative production 980 Bb
- Reserves 827 Bb, yet to find 153 Bb
- Production peaks and starts to decline at half of
recoverable resource, ca. 2008-2012 - Post-peak production will fall at about 2.7 per
year, dropping 75 in 30 years - Athabaska tar sands (300Bb) and Orinoco heavy oil
(300Bb) are environmentally damaging to extract
(and equal only 22 years current consumption)?
9The demand-production gap
- Present output 85m b/d, demand growing 1.1m b/d,
spare OPEC capacity 3.5m b/d - There are access and technical limits to
increasing production above 100m b/d - Oil production is declining in 33 of 48 largest
oil producing countries - Forecasts of 116-118m b/d by 2030 seem
unrealistic to industry insiders - Prices will rise to cut demand to fit available
production - (Ed Crooks and javier Blas, Financial Times, 9
November 2007)?
10Alternative fossil fuels
- Coal larger reserves but high mining impact,
less energy density, high pollution and CO2
emissions - Gas less polluting, but reserves also limited
- Methane hydrates in ocean sediments extraction
difficulties, potent greenhouse gas
11How much Coal?
- Official reserves 847 billion tonnes, but hard
coal reserves down 25 since 1990 some countries
have not adjusted reserves for decades - Production (2007) 6 bt, should rise 70 by 2030
- Reserves to production ratio 277 yrs in 2000,
155 yrs in 2005, 144 yrs in 2006 - Global consumption up 35 2000-2006, but price
rise has not increased reserves - Coal output could peak as early as 2025
12Our dependence on fossil fuels
- Road transport, shipping, aviation
- Chemical feedstocks, plastics, synthetics
- Energy/raw materials for industrial production
- Agricultural fertilizers
- Mechanized agriculture
- Electricity generation
- Heating and cooling, lighting
- Town planning, suburban lifestyle
- Global trade, food distribution
13Energy and Population
- 80 of global energy comes from fossil fuels,
which we must stop burning - to reduce global warming
- The world population has expanded sixfold,
exactly in parallel with oil production - Can the world maintain such a population without
the cheap energy from fossil fuels? - What will happen if it cannot?
14The question energy planners never ask
- Even if we could exploit every fossil fuel
reserve, can we really afford to cause so much
global warming?
15Fossil fuels and CO2
- Fuel oil produces 2.9 tonnes of CO2 from burning
1 tonne of oil equivalent (toe)? - Natural gas produces 2.1 tonnes CO2 per toe
- Coal produces 3.8 tonnes CO2 per toe
16Coal has a significant impact on global warming
- Major coal producing/ consuming countries US,
Australia, Japan, South Korea, India, China, have
45 of world population, consume 45 of world
energy, produce 52 of CO2, with both expected to
double by 2025 - China plans 560 new coal-fired power plants,
India 213 - 25 of global CO2 emissions come from coal-fired
power stations
17Controlling greenhouse gases?
- UN Framework Convention on Climate Change (Rio,
1992)? - Kyoto Protocol on reduction of greenhouse gases
return emissions to 1990 levels by 2012 - CO2 emissions rose 4.5 in 2004 to 27.5 b tonnes,
26 higher than 1990 - China and India have doubled CO2 production
since 1990, US 20, Australia 40 - US released 5.8, China 4.5, Europe 3.3, India 1.1
billion tonnes of CO2 in 2004
18The Nuclear Option?
- Cannot scale up to make a significant difference
- Uranium reserves are expected to be exhausted in
60-100 years - Research costs and development highly subsidized,
including by military uses - High energy input in construction and fuel
fabrication, not carbon free - Risks of accidents uninsurable
- Decommissioning costs not included (UK 140b)?
- UK unable to privatize its nuclear industry
- High waste disposal costs are imposed on future
generations, with no safe long-term disposal yet
found - Fusion still "40 years" off
19New Energy Technologies
- Hydrogen
- Fuel cells
- Metal nano-fuels
- still require a source of energy, fossil or
renewable
20Investment challenges
- The International Energy Agency estimates needed
investment in energy infrastructure at 22,000bn
by 2030 to replace ageing capacity and meet
growing demand (2 global GDP, 130 per person
per year)? - Responding to climate change would add 2,000bn
21Problems of energy economics
- Hidden subsidies are frequent
- Price instabilities produce windfall profits and
discourage investments - Reserve estimates are notoriously unreliable
- The market is politically manipulated 75 of
oil reserves are under government control - As with any addiction, users will pay anything to
maintain their habit
22The business community is worried
- Carbon Disclosure Project
- The Carbon Disclosure Project, representing a
group of 225 investors with 31 trillion of
assets under management, i.e more than 50 of the
worlds invested assets, has invited 2,100
companies worldwide to disclose
investment-relevant information concerning their
greenhouse gas emissions. - See http//www.cdproject.net
23Investment in developing countries
- The Clean Development Mechanism (CDM) of the
Kyoto Protocol will make available over 3bn of
carbon funds currently managed by public and
private bodies for investment in projects that
cut emissions of greenhouse gases. This new
source of finance for clean energy projects in
Africa and other developing countries is putting
them firmly back on the map for clean energy and
forestry project finance. - See Carbon finance for Africa - An Investors'
Guide - http//www.africapractice.com/case.html
24The politics of fossil fuels
- Fossil fuel reserves are concentrated in a few
regions, accentuating the unjust distribution of
wealth - The struggle to control reserves and access is a
major source of conflict - Since access to energy is a vital national
interest, these problems will increase as
supplies diminish - Only global management assuring just distribution
of energy resources can resolve this situation
25How do we go back to life without fossil fuels?
- Or can we go forward toward a new integrated
approach to energy capture and efficient use?
26HOW DOES NATURE DO IT?Energy management in
thecoral reef ecosystem
- Efficient solar energy capture by generating
large surface area - Efficient energy transfers within system,
symbioses - Little waste, effective recycling
- High complexity and integration
- Maximizes total productivity, not just most
productive
27Solar Energy
- The only long-term, large-scale
- energy source
28Plants are highly efficient solar energy devices
29Bio-fuels
- Wood
- Dung, animal wastes
- Ethanol
- Biodiesel
- Coconut, palm, rapeseed oils
- Bagass (sugar cane waste)?
- Biogas
- but their production will compete with food
production and other land uses
30Problems with biofuels
- Most present biofuel crops require high energy
inputs to grow, harvest and process, with little
net CO2 benefit (maize ethanol 0-12, soy
biodiesel 41)? - Competition with food production, raising food
prices - Pressure to clear tropical forest for oil palm
and soybeans - Area not sufficient to meet present fuel needs
(US only 5)
31Technologies for solar energy capture
- Photovoltaic
- Solar water heaters
- Parabolic reflectors (need steering)?
- Tubular captors with reflectors
- Greenhouse effect
- Passive solar heating in buildings
- but solar energy is diffuse, not concentrated
32Indirect solar power
- Water hydroelectric power is widely used where
resources permit - Wind commercially viable as part of a mix of
energy sources - Tides selected locations
- Waves engineering challenges
- OTEC ocean thermal energy conversion
- Chimney effect (air thermal gradients)?
33Energy efficiencythe first priority
- Reduce the resources and energy necessary to
maintain our standard of living - Factor 4 (von Weizsäcker, Lovins et Lovins, 1997.
Factor four Doubling wealth halving resource
use. Earthscan, London)? - Factor 10
- Targets adopted by OECD
- Examples more efficient appliances, reduce heat
loss from buildings, public transport
34 Where does our electric energy come from? Total
Electricity Generation Worldwide
(TWh) (source
International Energy Agency 2002)? World
Alliance for Decentralized Energy (WADE)
http//www.localpower.org
35Centralized versus decentralized
- The Western economic system has encouraged
centralized energy systems (large generating
stations, large dams, large refineries, extensive
power grids)? - Transmission produces large losses
- Small-scale systems close to users do not
interest large corporations - Solar energy and most renewables are inherently
decentralized - The economic system biases technology choice
36Some strategies
- Iceland hydrogen economy
- Sweden plan for oil-free economy by 2020
- Sustainable electricity in Geneva 86
- Village in Luxembourg
- Hawaii Energy for Tomorrow (efficiency,
renewables, biofuels, hydrogen technology,
consumer incentives)?

- http//www.wbcsd.org
41Barriers to change
- the biggest obstacles to the take up of
technologies such as renewable - sources of energy and "clean coal" lie in vested
interests, cultural barriers to change and simple
lack of awareness. - - Avoiding Dangerous Climate Change, UK
Meteorological Office - - from http//www.unepfi.org/ebulletin
42The double challenge
- On current trends, ...humanity will need twice
as much energy as it uses today within 35
years.... Produce too little energy, say the
economists, and there will be price hikes and a
financial crash unlike any the world has ever
known, with possible resource wars, depression
and famine. Produce the wrong sort of energy, say
the climate scientists, and we will have more
droughts, floods, rising seas and worldwide
economic disaster with runaway global warming. - John Vidal in The Guardian Weekly, 9-15 February
2007, Energy supplement, p. 3
43Ways forward
- Harness all available sources of energy on the
surface of the planet - Reduce environmental impact to sustainable limits
- Accelerate the transition to reduce the shock
- Create global governance mechanisms to manage
this global challenge - Share the cost, effort and benefits globally with
equity and justice
44Things you can do
- Walk, bicycle or use public transport
- Make your personal residence energy efficient
(light bulbs, appliances,no standby,
heating/cooling, etc.)? - Choose electricity from renewable sources if
available - Consume less, buy local
- Consider the energy implications of everything
you do
45Building a sustainable energy future is a major
challenge for your generation
