Energy Data

This brief summary provides an overview of energy statistics, including primary energy sources, emissions, economics, efficiency indicators, and technology. It includes links to reputable sources such as the UN, BP, EIA, and IEA. The summary also explains how primary energy is calculated and provides equivalence factors for different energy forms.

  1. Energy Data A brief summary Arnulf Grubler

  2. Energy Statistics • Energy use:-- UN since 1929 (no online access)-- BP (fastest update) Publications – Statistical Review http://www.bp.comBP + UN: Primary energy supply by source (no non-commercial)-- EIA (US): Primary and secondary energy (no final, no non-commercial)-- IEA: supply and disposition (primary and final energy by fuel …and sector; incl. non-comm. [OK since ca. 1995]) http://www.iea.org/Textbase/stats/index.asp • Emissions: All gases/sources: EDGAR http://www.mnp.nl/edgar/CO2: IEA (see class server) and UN based (http://cdiac.esd.ornl.gov/trends/trends.htm), energy focus! • Economics:-- IEA Energy prices and Taxes (see class server) end-use focus, no upstream and no cost data • Efficiency: only imputed indicators (intensities), cf. IEA (rather than EIA!) • Technology: no official statistics, individual efforts e.g. IIASA CO2DB

  3. Austria Energy Balance 2001 (1000 toe): Supply Arnulf Grubler

  4. Austria Energy Balance 2001 (1000 toe): Disposition IEA: Energy Balances (common energy unit) and Energy Statistics (physical units) Arnulf Grubler

  5. PE Accounting Methods of IEA/BP • Substitution equivalent for nuclear • Calculate PE as: “…the primary heat equivalent of the electricity produced by a nuclear power plant with an average thermal efficiency of 33%.” • Primary energy form = heat - Geothermal: assumes 10% thermal efficiency • Direct equivalent for hydro, solar, wind • “Hydro shows the energy content of the electricity produced in hydro power plants.” w/ no thermal efficiency factor. • Primary energy form = electricity (assumes 100% efficiency) • Result • Nuclear = weighted to be larger proportion of TPES than hydro, solar and wind US EIA does not publish equivalence factors used(implied direct equivalent for all non-fossils)
