2. Energy Statistics Energy use: -- UN since 1929 (no online access) -- BP (fastest update) Publications – Statistical Review http://www.bp.com BP + 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.asphttp://www.bp.com Emissions: All gases/sources: EDGAR http://www.mnp.nl/edgar/ CO 2 : IEA (see class server) and UN based (http://cdiac.esd.ornl.gov/trends/trends.htm), energy focus!http://cdiac.esd.ornl.gov/trends/trends.htm 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

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)
