Title: The needs and possibilities for improving the energy balance system


1
The needs and possibilities for improving the
energy balance system
  • Ann Christin Bøeng, Statistics Norway

2
Disposition of this presentation
  • Purpose with the energy balance
  • Why do we need an updated manual on energy
    balances?
  • Challenges in the work with the energy balance
  • Is it possible to merge information from the
    energy accounts and energy balance into one table

3
Purposes with the energy balance
  • Show in one table the overall picture of energy
    production, conversion and consumption for each
    fuel utilised in the country
  • Provide background information to the countries
    energy planning - Give a good picture of the
    countries energy situation - Show changes over
    time.
  • Basis for emission calculations
  • Basis for calculations of value figures for
    energy in the National Accounts.
  • Energy research and basis for preparing energy
    indicators
  • Public information to media etc.

4
Main principles in the energy balance
5
The needs for a new manual on energy balances
  • UNs manual for how to set up the energy balance
    is old, and needs a refreshment
  • A more user-friendly and easy available manual
    would probably increase the use of it.
  • There are just as many variants of the energy
    balance as the number of countries that prepare
    this. Some of the differences are due to lack of
    knowledge or that the international
    recommendations not are clear.

6
Different countries- different needs
  • Needs for guidance differ for different countries
  • Most developed countries have established a
    system for preparing the energy balance.
  • Not all developing countries have an energy
    balance, or energy statistics at all.
  • While many developed countries only needs some
    minor quality improvement in their energy
    statistics, some countries have to start from
    scratch
  • These countries have the most urgent need for
    guidance and will probably be the most active
    user of a new manual.

7
  • A new manual for energy balance should be
    prepared in a way that all countries can use it -
    independent of their background knowledge of
    energy statistics.
  • This means, it must include both basic
    information for countries that not have a energy
    statistics system at all..
  • ..and recommendations for countries that already
    have a system, but could need some advise in
    order to improve the quality.
  • Include best practices on problematic issues in
    the energy balance.
  • Preferably cover several purposes, as for
    emission calculations, National accounts, energy
    planning etc.

8
Energy balance vs energy accounts (from a
Norwegian point of view)
  • Statistics Norway publish both the energy balance
    and the energy accounts.
  • Both show supply, transformation and consumption
    of each fuel, and they are presented in the same
    units
  • There are some differences in the principles and
    definitions
  • Energy balance follows international standards
  • Energy accounts follows the energy consumption in
    Norwegian economic activity in the same way as
    the National Accounts.

9
Background for the Energy accounts
  • Closer link between the energy balance and the
    National Accounts.
  • Originally a claim from the Research Department
    in Statistics Norway.
  • Necessary for emission calculations by sector.
  • Can be used for preparing energy indicators,
    based on coupling of the energy accounts and
    National accounts.

10
Main differences in energy accounts and energy
balance
  • Energy balance excludes energy used in Norwegian
    vessels etc. abroad while the energy accounts
    includes this.
  • Foreigners use of energy in Norway are included
    in the energy balance, but excluded in the energy
    accounts.
  • Energy used as raw materials in industry is put
    on a separate line in the energy balance, but
    added with other energy consumption in the energy
    accounts
  • Energy for consumption purposes is put on the
    transport sector in the balance, but on the
    sector that actually use it in the energy accounts

11
The users frustrations
  • Most figures are equal in these balances, but
    differences in principles and methods imply that
    some important figures differ.
  • The users dont know which of the two balance
    systems that are most relevant for them. Its
    often random what they use.
  • Several users of the energy balance would prefer
    one single table where information from these
    systems are integrated.
  • The point with the two systems are to satisfy
    several needs. By merging the information, you
    will cover several needs in one table, and also
    avoid the users confusion (hopefully)

12
  • From our experiences we know that many are very
    interested in energy consumption by purpose, and
    the split between stationary consumption, energy
    for raw materials and energy for transport.
  • But they also wants to know where, and in which
    sector the consumption for different purposes
    takes place.

13
Merging energy accounts and energy balance
  • Our suggestion for maintaining information from
    both these balances in one table (very simplified
    model)

14
Explanation of the table
  • The upper rows in the table illustrate the energy
    account approach.
  • The lower parts of the table show energy used for
    transport and energy used as raw materials
    separate, as the energy balance does, but by
    sector.
  • Differences in territorial boundaries affects
    only a few figures for foreign shipping, air
    traffic and fishing. Could be covered by adding
    some additional rows in the table, or in a
    separate smaller table.
  • A more detailed plan and discussion for how to
    merge these tables is available in a paper on the
    ocg-web-site.

15
Energy balance quality depends on more than
principles
  • The quality on the energy balance depends a great
    deal on the primary energy statistics, as figures
    for production, imports, exports.
  • Consumption in some user groups are more
    problematic than other f.ex.
  • - Consumption in the service sector (often
    calculated as a rest)
  • - The split between energy used for transport
    domestic and abroad.
  • - Consumption for transformation purposes in
    thermal power plants (often calculated).

16
The measuring problem of renewable energy and
energy technologies.
  • Renewable energy sources and technologies (f.ex.
    biomass, solar energy and heat pumps)
  • Biomass is in large degree a non-commercial
    energy bearer, and difficult to measure.
  • Solar energy and energy from heat pumps is
    difficult to measure. Should it be included in
    the energy statistics or not, and is it possible
    to find good methods for measuring this?

17
Challenges in oil and gas statistics
  • Different classifications, aggregation levels and
    conversion factors.
  • How should for example liquid petroleum gas (LPG
    ), petrol coke or NGL be classified ?
  • Oil products The basis unit are tonnes, but is
    converted to a joint unit in the energy balance,
    on basis of a theoretical energy contents.
  • The theoretical energy contents vary between
    different oil fields, oil products, countries and
    organizations.
  • Natural gas The figures depend on if gross or
    net calorific value is used. The difference is
    about ten per cent.

18
How to improve input data and methods ?
  • As already mentioned in earlier presentations
    Exchange experiences and best-practices. Utilize
    the competence from each country
  • Use the electronic discussion forum for the Oslo
    group more active.
  • Writing drafts that can be used as a contribution
    for a new manual. For example describing own
    system and advantages / drawbacks with this.
  • We could also need views and advices from
    countries that dont set up the energy balances,
    but intend to do that.

19
  • Our intention is to implement improvements in the
    energy balance system at the same time as we have
    to adapt it to the revised classification for
    economic activity (revised NACE / ISIC). A good
    opportunity also for other to make changes ?
