Title: The needs and possibilities for improving the energy balance system
1The needs and possibilities for improving the
energy balance system
- Ann Christin Bøeng, Statistics Norway
2Disposition 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
3Purposes 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.
4Main principles in the energy balance
5The 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.
6Different 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.
8Energy 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.
9Background 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.
10Main 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
11The 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.
13Merging energy accounts and energy balance
- Our suggestion for maintaining information from
both these balances in one table (very simplified
model) -
14Explanation 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.
15Energy 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).
16The 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?
17Challenges 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.
18How 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 ? - Thank you for your
