 The transparency this provides also attests to the reliability and accuracy of these data sources. The //Energy Statistics Act// (Energiestatistikgesetz) has no separate paragraph relative to surveys on the domestic coal sector; its refers instead explicitly to the functioning system of coal statistics. The transparency this provides also attests to the reliability and accuracy of these data sources.

 Such changes in the available statistics have made it necessary to adjust the methods used for the Energy Balances – especially for their descriptions of industrial final energy consumption. As a consequence of the described expansion in the data supply, separate data on fuel inputs as of 2003 for industrial electricity generation – i.e. for electricity-only generation – are now available. The Federal Statistical Öffice does not collect data on breakdowns of fuel inputs by "electricity" and "heat" in industrial and public-supply combined heat / power generation (CHP) systems; such statistics are collected by the AGEB and estimated by institutes it commissions.  Such changes in the available statistics have made it necessary to adjust the methods used for the Energy Balances – especially for their descriptions of industrial final energy consumption.

 With regard to quality assurance, the Finnish method makes calculations relative to power/heat production for the public supply and for industry logical and transparent. The necessary pertinent framework assumptions, such as the reference efficiencies of non-CHP generation as provided in the documentation for the Energy Balances, are clearly stated in the process.  With regard to quality assurance, the Finnish method makes calculations relative to power/heat production for the public supply and for industry logical and transparent.

 The figures on electricity generation from biomass, and on biomass-fuel inputs in decentralised CHP systems, are based on internal calculations of the Working Group on Energy Balances (AGEB). In this connection, a method is used that was developed by ZSW and EEFA in the framework of reporting to IEA and Eurostat. With regard to wood consumption in the Residential and Commercial / Institutional sectors, figures of RWI/forsa and of the Thu nen Institute were carried forward. Figures for electricity generation and fuel inputs in small CHP systems fired with natural gas and HEL (< 1 MW) were calculated with data the BHKW (compact combined heat-and-power (CHP) generating systems) database of the Öko-Institut e.V. Institute for Applied Ecology. The same data are used for reporting in the IEA/Eurostat context. The figures on electricity generation from biomass, and on biomass-fuel inputs in decentralised CHP systems, are based on internal calculations of the Working Group on Energy Balances (AGEB).
