SEEA and Energy
Includes various accounts relevant for describing and analysing the role of energy in the economy and the links to the environment
Methodology based on national accounts’ definitions and framework
Supply-use tables and balancing (supply = use)
Asset accounts (opening stock + changes = closing stock)
Physical and monetary
Residence principle in stead of territory principle
Same classifications as used in the national accounts, e.g. ISIC

Purpose of the physical energy flow accounts
Describe Extraction and capture of energy from environment Transaction of energy within the economy The losses of energy and residual flows back to the
environment
Measurement unit: In principle all natural units can be used (depending
on purpose) Tonnes, cubic metres, litres, but most often practical to use a common unit like Joules

Energy products
![Page 6: Physical Energy Accounts Ole Gravgård SEEA Training Seminar for the ECA Addis Ababa 2-5 February 2015.](https://reader035.fdocuments.us/reader035/viewer/2022081516/56649f3b5503460f94c5a009/html5/thumbnails/6.jpg)

Energy products: SIEC – Standard International Energy Classification
Part of the International recommendations for Energy Statistics
http://unstats.un.org/unsd/statcom/doc11/BG-IRES.pdf
Also recommended for the SEEAenergy Accounts
No one-to-one relationship between CPC and SIEC

Energy Residuals
Energy residuals, Joules
Losses of energy during- extraction- distribution- storage- transformation- others (= end use of energy - by industries and households)
Energy residuals - weight

USE table for energy - JOULES I – NATURAL INPUTS and PRODUCTS

USE table for energy - JOULESII – PRODUCTS (cont’d) and RESIDUALS

Various balances in the supply and use tables must apply
Balances for ”energy”: Supply of products=use of products Supply of natural inputs=use of natural inputs Supply of residuals=use of residuals Total supply = total use
Balances for industries and households:
Total inputs must equal total outputs + Net additions to stocks (accumulation)

Implementation in countries
The SEEA Central Framework tables are generic: • Not all items are relevant for all countries • In some cases it is useful with more details
You need to decide what is most relevant and where to start
Start with what is available and focus on the elephants – not the mices

Sources, etc. for the energy accounts
Energy statistics Energy balances Foreign trade statistics Production statistics Agricultural/forestry statistics, etc. Monetary data and unit prices
Often necessary to make estimations and assumptions
Note that defintions and borderlines may be different in different statistical sources

Basic Energy Statistics
Energy Balances Energy Accounts
Statistics on natural gas
Statistics on crude oil
Statistics on oil productsStatistics on electricity
Statistics on biomass
• Energy statistics serves different purposes and are presented in different ways
• Energy statistics put together on standardised form
• Production and consumption
• Territory principle
• Detailed description of the energy sector
• Transport treated as individual sector
• The basis is the energy balances
• Complemented with data on international transportation etc
• Information on prices and values
• Supply always equals the use
• National accounts concepts
• Residence principle
•No statistical discrepancies
Etc.
Physical units Physical and monetary units
Geographic area
Economy as described in the
national accounts
Other sources• International transportation between third countries• Prices and values• Etc

Other publications that are useful for energy accounting
International Recommendations for Energy Statistics (IRES)
Adopted by the United Nations Statistical Commission, in 2011.
Complete set of recommendations covering all aspects of the statistical production process framework, from basic concepts, definitions and classifications to data sources, data compilation strategies, energy balances, data quality and statistical dissemination.

SEEA Energy
SEEA-Energy, a SEEA 'sub-system', is under development to provide compilers and analysts with agreed concepts, definitions, classifications, tables, and accounts for energy and energy-related air emission accounts. SEEA-Energy elaborates and expands the guidance on accounting included in the IRES and is fully coherent with the broader SEEA.
