SEEA/Environmental accountings’ user needs with regards to renewable energy

Julie L. Hass, Ph.D.

Kristine E. Kolshus

Division for Environmental Statistics

Statistics Norway

London Group Meeting

17-19 December 2007

Rome, Italy

goals
Goals:
  • Where are renewables an important category?
    • example from energy statistics, sustainable development indicators
  • What are renewables? Definition(s)?
  • What type of information is needed about renewables with respect to environmental accounting/statistics?
  • Identify SEEA-user needs to be able to communicate to others that are also working in this area.
fuel shares of world total primary energy supply tpes
Fuel shares of world total primary energy supply (TPES)

** Geothermal, solar, wind, tide/wave/ocean. Totals in graph might not add up due to rounding.

slide4

Energy use per unit GDP1 and total energy use (PJ) for renewable and non-renewable energy sources. 1976-2004 (official Norwegian sustainable development indicator)

challenges with renewables with norwegian sdi
For energy in general:

Systems boundaries & coverage, break down by institutional units, terminology

For renewables:

Classification of renewables

Coordination between renewables classification and product classifications (HS/CPA/SITC)

Information regarding the sources of the energy used – how it was produced

System boundary – GDP vs Kyoto related energy use

Definition of “renewables” – what to include?

Waste

Import of electricity (99% of Norwegian electricity production from hydro sources) – need to know production source of imported electricity

Are all own-use/auxillary energy included? Biogas from sewage treatment facilities (newer energy sources) – coverage?

Challenges… - with renewables: - with Norwegian SDI:
iea renewable energy commodity categories
IEA Renewable energy commodity categories
  • Combustible Renewables and Waste:
    • Solid Biomass
    • Wood, Wood Waste, Other Solid Waste
    • Charcoal
    • Biogas
    • Liquid Biofuels
    • Municipal Waste (renewables)*
  • Hydropower
  • Geothermal Energy
  • Solar Energy
  • Wind Energy
  • Tide/Wave/Ocean Energy

*Some of the waste (the non-biodegradable part of the waste) is not considered renewables as such. However, proper breakdown between renewables and non-renewables is not always available.

Source: IEA (2007a) Renewables Fact Sheet – page 23

slide7

IEA/OECD-Eurostat-UNECE energy manual, page 116

Is this electricity-only vs. Stock and/or non-stock?

Then where to place hydro since that has water reserve basins that are stocks (in the sense of the word used here like solid biomass)?

slide8

Renewables and Waste

Electricity-only renewable sources (Group I)

Multiple use renewable sources (electricity, heat, etc.)

Renewable sources without stock changes (Group II)

Renewable sources with stock changes (Group III)

liquid biofuels
Liquid biofuels
  • Increasing interest - specific biofuel goals - March 2007 European Council: raise the share of biofuels in transport to 10 per cent by 2020
  • How to measure this?
  • “As there is no specific customs classification for biofuels, the exact amount of imported ethanol, oilseeds and vegetable oil ultimately used in the transport sector cannot be quantified.”
  • “…assessment will have to specify whether the focus should be on CN codes (internal EU) or on international HS codes. Creating a new HS code requires international negotiation, while a new CN code may be appropriate for EU statistical purposes.”
biofuels hidden in hs codes
Biofuels “hidden” in HS codes

“Beverages, spirits & vinegar” (chapter 22):

  • Bioethanol denatured HS Code 22072000
  • Bioethanol undenatured HS Code 22071000

“Miscellaneous chemical products” (chapter 38):

  • Biodiesel HS Code 38249099
clean green emissions free electricity production use imports and exports
“Clean/green/emissions free” electricity production, use, imports and exports
  • European Electricity Directive 2003/54/EC of 26 June 2003 concerning common rules for the internal market in electricity:
  • Member States shall ensure that electricity suppliers specify in or with the bills and in promotional materials made available to final customers:
    • the contribution of each energy source to the overall fuel mix of the supplier over the preceding year;
    • at least the reference to existing reference sources, such as web-pages, where information on the environmental impact, in terms of at least emissions of CO2 and the radioactive waste resulting from the electricity produced by the overall fuel mix of the supplier over the preceding year is publicly available.
  • With respect to electricity obtained via an electricity exchange or imported from an undertaking situated outside the Community, aggregate figures provided by the exchange or the undertaking in question over the preceding year maybe used.
need new products that also include production technique source information
Currently: electricity

Do we need?

Electricity from nuclear

Electricity from hydro

Electricity from coal

Electricity from waste

Etc.

Is this practically possible?

Bioethanol

From crops such as corn, sugar beet, palm oil, vegatable oil

From cellulosic biomass feedstock

Etc.

NACE Rev. 1.1

40.110 Production of electricity

NACE Rev. 2

35.11 Production of electricity…

35.111 …from hydro

35.112 …from wind

35.113 …from biofuels, waste and landfill gases

35.114 …from natural gas

35.115 …from other sources

Need new products that also include production technique/source information ?
conclusion
Conclusion
  • Terminology is confusing and needs to be harmonized – Oslo Group actively working on this
  • A number of fora are involved in discussing product categories for renewables, for example a Eurostat working group. LG should coordinate with these energy and trade experts to provide input to the revision of the standard product categories in the standards (HS/CPA/SITC)
  • What is different with regards to renewables is the need to identify how the energy is produced and/or transformed. How to solve this? More detailed product and source product categories?
