Introduction
This 21st WEC Survey of Energy Resources contains a chapter
for each energy resource, ranging from the conventional fossil
fuels to the renewables, both new and traditional. Generally,
the coverage of each resource comprises a Commentary by a leading
expert in the field, followed by Definitions, Tables and Country
Notes. The tables summarise the worldwide resources, reserves,
production and consumption of fossil fuels and comparable data
for non-fossil energy sources, as applicable. The Country Notes
aim to highlight the main features of the resource and its utilisation.
¡Reserves/Resources - where relevant, tables of fossil fuels
provide reserve statistics (covered globally from WEC and non-WEC
sources) and amounts in place (as reported by the WEC Member
Committees);
¡Tabulations - data tables are arranged on a standard regional
basis throughout;
¡Units - where relevant, data have been provided in alternative
units (cubic feet as well as cubic metres, barrels as well as
tonnes) in order to facilitate use of survey data in an industry
context;
¡References and Sources - as far as possible, these have been
consolidated in introductory notes to the data tables and country
notes, or appended to the commentaries on each resource. |
Any review of energy resources is critically dependent upon the
availability of data and reliable, comprehensive information does
not always exist. While the basis of the compilation is the input
provided by the WEC Member Committees, completion necessitates
recourse to a multitude of national and international sources
and, in some cases, to estimation. Difficulties in obtaining information
continue to be compounded by trends in the energy sector. As further
deregulation and privatisation take place, the availability of
data tends to be reduced as some data-reporting channels may be
lost or specific items become confidential. Moreover, problems
in the quantification of energy resources persist, in particular
for those universally-found resources: solar energy, wind power
and bioenergy, owing to their evolutionary status and generally
decentralised nature.
Notwithstanding the efforts of the UN/ECE Ad Hoc Group of Experts
to codify and standardise the terminology of reserves and resources
reporting (UN Framework Classification for Fossil Energy and Mineral
Resources), it remains a fact that, at the present time, almost
every country that possesses significant amounts of mineral resources
has developed its own unique set of expressions and definitions.
Whilst the UN continues its work on harmonisation of the terminology,
it will take some considerable time before the theory can be applied
globally. It is customary for nationallevel reserves and resources
to be reassessed only infrequently. The improvement in reporting
will thus occur gradually over a period of time as reassessments
are undertaken and subsequently reported on a codified basis.
In the meantime, the resources and reserves specified
in the present Survey conform as far as possible with the established
definitions specified by the WEC. It is a matter of judgement
for each member country to determine which, among the available
assessments of resources and reserves, best meet these definitions.
A similar approach has been followed for non-reporting countries,
for which the Editors have selected the levels of reserves which,
in their opinion, are most appropriate.
This Survey is testament to the effect of a raised oil
price and increasing concern with aspects of climate change and
energy sustainability.
Resources and technologies that were previously uneconomic to
develop are now seeing enhanced R&D, with many schemes being
implemented or approaching fruition.
Particular points of emphasis in the present Survey:
¡ coverage of fossil fuel reserves, particularly in respect of
coal, has been improved by establishing the recoverable portion
of the in-place quantities in a number of countries where this
had not been previously reported;
¡ wood energy has been included with other biofuels;
¡ coverage of oil shale, natural bitumen, solar/PV, wind energy
and the marine technologies has been expanded and improved to
reflect their changing prospects. |
As Editors, we strive to develop and maintain contacts in the
energy world and hope that in time the availability of data will
not only improve
but expand to cover those energy resources that presently go unrecorded
(or under-recorded).
We are grateful to all those who have helped to produce this Survey:
we extend our thanks to the WEC Member Committees, to the authors
of
the Commentaries, to Nada Zupanc, Bob Schock and the Studies Committee
for guiding the production of the Survey and to Valli Moosa

Overview
gEnergy is essential for development, yet two billion people
currently go without, condemning them to remain in the poverty
trap. We need to make clean energy supplies accessible and affordable.
We need to increase the use of renewable energy sources and improve
energy efficiency. And we must not flinch from addressing the
issue of over consumption - the fact that people in the developed
countries use far more energy
per capita than those in the developing worldh (Kofi Annan, Secretary
General, United Nations.) |
Introduction
The availability of energy resources is of paramount importance
to society. This new World Energy Council Survey of Energy
Resources addresses the question of future availability at
a critical time in the development of global economies and the
people who depend on them. The fundamental dilemma facing us is
that energy is a vital ingredient for growth and sustainable development,
and for the vast majority of economic activities, but that energy
production and use contribute to global warming. The greatest
challenge facing the energy sector today is how to meet rising
demand for energy, whilst at the same time reducing our emissions
of greenhouse gases. Climate change is undoubtedly an imperative
which must be
addressed with a sense of urgency. We need to find new and innovative
ways of addressing mitigation of greenhouse gases as well as adapting
to changes in the climate. Given that the energy sector is critical
to the functioning of most economies, is long term in nature and
is very vulnerable to the negative impacts of climate change,
this issue should be at the top of everyonefs agenda.
Resources are the backbone of every economy. In using resources
and transforming them, capital stocks are built up which add to
the wealth of present and future generations. However, the dimensions
of our current resource use are such that the chances of future
generations having access to their fair share of scarce resources
are endangered. We therefore need to ensure the sustainable use
of our natural resources through the creation of a longterm sustainable
base and much greater focus throughout the energy value chain.
Access to energy and security of supply
Lack of access to energy hampers economic and social development
in many regions and is an obstacle to the achievement of social,
environmental and economic progress worldwide. Access to reliable,
affordable commercial energy provides the basis for heat, light,
mobility, communications and agricultural and industrial capacity
in modern society. Energy is important for development as is demonstrated
in consumption trends . notably, the increase foreseen in energy
demand, for example the International Energy Agency estimates
an increase of 60% by 2030, (World Energy Outlook, 2002). This
increasing demand will have to be met by a complex mix of energy
resources in order to meet a wide variety of
energy needs, whilst considering environmental Overview and other
constraints. Meeting societyfs needs, aspirations and expectations
for a better life will require growing supplies of reliable, affordable
and lower-carbon energy.
Multi-Energy Systems
We need to continue to keep all energy options open and to develop,
as appropriate, all primary energy supplies. Keeping all energy
options
available will enable every nation to tailor its approach to addressing
energy needs and climate change in the most efficient way, in
alignment with their respective resource base and long-term strategic
development objectives. One critical tool in the arsenal is energy
efficiency, as it is a critical component of any comprehensive
sustainable energy strategy and can make a significant and short-term
impact on emissions of greenhouse gases. Energy efficiency needs
to be promoted among producers and consumers of energy through
the establishment of appropriate fiscal and regulatory frameworks.
However more action is needed to turn ideas into action. Globally
everyone needs to identify opportunities to
reduce their consumption of energy and improve efficiency. Many
countries and companies are doing exactly that . and some will
be left behind
if they do not also rise to the occasion.
At the same time it does not help to address only one element
of the energy sector. Energy supply and use pose political and
economic issues related to economic growth, security, employment,
investment, climate change, environmental impacts and trade. Consequently,
energy challenges should be addressed through integrated policies
reflecting a broad range of issues including development priorities
and needs; social conditions and
aspirations; trade rules; environmental policies; and the promotion
of innovation, together with technology development and transfer
policies
and energy efficiency. Climate change is a multifaceted and broad-based
issue and thus it is particularly important that climate change
issues are integrated into all relevant policies.
The long road ahead
Let us not fail to fully understand the magnitude of the challenge
facing us. The challenge that we face is bigger than one country
or company
and the evolution of energy systems will require considerable
time and expense in order to alter energy and raw material inputs,
operations and
products and to develop and introduce technological innovations,
as well as to establish the infrastructure to support them. Companies
and governments should take these long-term considerations and
realities into account, and strive for consistency and predictability
over the corresponding time span.
Maintaining and growing the energy supplies required to provide
access to those lacking it and to meet future demand with reduced
environmental impacts will require significant investment in the
long term in every element of the supply and use chain. This investment
is estimated by the IEA to be US$ 20 trillion by 2030. Mobilising
the required energy investments will be a key challenge. In countries
with limited capital, and specifically for the leastdeveloped
countries, the role of Foreign Direct Investment should be complemented
by Inter-Governmental Organisation funds, Official
Development Assistance (ODA), and local private funds. Through
such innovative financing solutions, project creation and implementation
benefit from a variety of sources of funds, which are mutually
reinforcing, each fund being adapted to the type of investment
and risks it covers.
The challenge of climate change adds an additional dimension to
this issue and historical paradigms of investment in infrastructure
must be challenged if we are to meet the challenges of ridding
the world of energy starvation through a cleaner and lower carbon-emitting
path. In
adopting a holistic approach to this value chain there is a significant
opportunity for the public and private sector to work together
to build lower
carbon-emitting energy infrastructure and then use it for economic,
social and environmental development.
Energy for sustainable development will depend on the more widespread
use of existing efficient technologies as well as the development,
commercialisation and deployment of innovative and lower-carbon
technologies. To expand and take advantage of the full potential
of energy
options, all relevant stakeholders should allocate resources to
research and development of new technologies all along the energy
chain. The energy sector dedicates substantial resources to technology
advancement and the development of innovation but we also need
to be a partner in
defining mechanisms to identify, develop, commercialise and transfer
technologies on a global scale. In order to accelerate the development
and deployment of technologies, large demonstration or pilot activities
should be considered in order to develop capacity and to increase
the rate of uptake of key technologies. While fossil fuels will
continue to play an important role in energy supply in the decades
to come, every effort must be made to diversify the energy mix.
Urgent action is required to further diversify energy supply by
developing advanced, cleaner, more efficient, affordable and costeffective
energy technologies such as renewables (including large-scale
hydropower) and nuclear power. In addition, quantum leaps need
to be made in the implementation of energy efficiency measures.
Further, in areas were water is scarce, the application of technologies
such as dry cooling, needs to be employed. The publication of
the data in this report can provide the foundation for sustainable
energy planning as we move forward
This transformation, as well as meeting the need for skills to
build and operate plant is critical. Education is essential to
supporting research and facilitating efficient deployment and
operation of energy technologies. Furthermore, education is important
for helping users to make informed energy choices.
Conclusion
We know that the energy sector is a major contributor to global
greenhouse gas emissions and in order to meet the challenges of
meeting the rising demand for energy whilst reducing greenhouse
gas emissions and adapting to the impacts of a changing climate,
global efforts will be required. This has been the subject of
the recently released WEC report on Energy and Climate Change.
The efforts in this area require concerted action which replicates
successes around the world and through public-private partnerships
which leverage resources and channel international effort. The
energy sector will not only be a key implementer of global policy,
but will also contribute through innovation and the development
and deployment of new technologies. It is recognised that there
is no technological gsilver bulleth but that all technologies
are important to assess, including renewables and clean-coal technologies.
In addition, technologies that result in significant cuts in greenhouse
gases, such as nuclear
power, have a crucial role to play. Carbon markets also have an
important role to play and should be encouraged and normalised
as far as possible.
In conclusion, I am a firm believer in the words of an eighteenth
century British MP Edmund Burke, who said gNobody made a greater
mistake than he who did nothing because he could only do a littleh.
We all play a vital role in contributing towards global imperatives
and we need to define novel ways in which to leverage resources
in meeting the challenges we collectively face.
