Renewables Information - IEA Online Database
Renewables Information is an annually updated database providing sound market information on renewable and waste energies to policy and market analysts, and those em-ployed in all sectors of the renewables industry.
This monitoring and reporting of historical trends as well as the current energy market situation pro-vides a strong foundation for policy and market analysis, to better inform the policy decision proc-ess towards policy instruments that are best suited to meet domestic and international objectives.
Renewables Information brings together in one volume the basic statistics compiled by the IEA on renewable and waste energy sources. It covers production, trade, transformation to electricity and heat, final consumption and installed generating capacity from renewable and waste energy sources.
The OECD data shown in this publication are primarily based on information provided to the IEA’s Energy Statistics Division (ESD) in the Annual Renewables and Waste Questionnaire. This questionnaire is completed by the national administrations of the OECD member countries and provides statistics for electricity and heat production, primary supply, transformation sector, end-use consumption and installed capacity for electricity generation from renewable sources. The Annual Renewables and Waste Questionnaire was implemented in August 2000 and is a joint questionnaire between the IEA, Eurostat and the Statistical Division of the Economic Commission for Europe of the United Nations.
The non-OECD data were collected by the non-member section of ESD, which receives its data from the Annual Renewables and Waste Questionnaire for some countries and from secondary sources for the other countries.
The collection of the data presents national administrations with some unique challenges. Renewable energy systems tend to be smaller than conventional systems, and harder to track. Operators tend to be more diverse and a much larger population. Many systems are connected to the grid at the distribution level rather than the transmission level and so do not require interconnection permits. National governments are now seeking to improve data collection methods to reflect the particular nature of renewable energies. In general, the dispersion of renewables and waste production, specifically that of the off-grid production (such as domestic solar collectors and/or small wind turbines), creates transparency and measurement problems. Thus, the nature and structure of the renewable energy market impedes data quality and reliability when compared to that of the traditional fossil fuels, which are mainly pro-duced in grid-connected plants.
In order to improve the quality of renewables and waste statistics and to ensure data compatibility, the IEA initiated a project in 2002 to compare and harmonise historical IEA data with those of national administrations and/or Eurostat, where applicable. Due to the unavailability or inaccuracy of renewables and waste statistics before 1990, emphasis was put on the reconciliation of data after 1990. Thus, 1990 is the first year reported in this database. Minor discrepancies between the different data-collecting bodies may remain in the early years of our analysis because renewable energy classification systems were not well established and coordination between the member countries was poorly developed.
Where possible, these discrepancies have been resolved and the following pages incorporate the results of the reconciliation process. Differences from national or Eurostat statistics are retained where different definitions of renewable energy are applied or where IEA data are more accurate.
Country notes and individual country data should be consulted when using regional aggregates. IEA analysis suggests that data are more accurate for electricity and heat production, and electricity generation capacity, than for supply and final con-sumption of renewable and waste energy.
The OECD currently has 30 Member countries. Energy data for all Member countries are presented in this publication and included in all OECD totals or regional aggregates.
The IEA has 26 member countries; Iceland, Mexico, Poland and the Slovak Republic are members of the OECD but not of the IEA.
The tables listed below are presented in the format very similar to those published in the book but data for all available years are provided, generally from
1990 onwards.
Renewables Information - OECD Tables
- Energy Supply, GDP and Population:
This table provides a full set of main indicators for each OECD aggregate and Member country such as TPES, percentage of renewables, GDP, population, electricity generation and the share of electricity produced from renewable products.
- Net Generating Capacity of Renewable and Waste Products (MW):
This table shows a comprehensive status of net electrical capacity by type of fuel, as well as solar collectors’ surface.
- Gross Electricity and Heat Generation from Renewable Sources (GWh, TJ):
This table presents gross electricity and heat production from each of the renewable and waste sources as well as the breakdown according to the type of plant (electricity only, CHP or heat only). It should be noted that the heat part of this table is not available for all countries.
- Primary Energy Supply, Transformation and Final Consumption of Renewable Products:
In this table, a balance for different products is shown. These products are: geothermal, solar ther-mal, industrial waste, renewable and non-renewable municipal waste, solid biomass, gas from biomass and liquid biofuels. In the case of geothermal, if transformation inputs are not sub-mitted by the national administrations they are estimated based on 10% efficiency for electricity generation and 50% efficiency for heat generation. Solar photovoltaic and thermal transformation in-puts into electricity and heat production are estimated at 100% efficiency (based on the IEA methodology that the first energy form down-stream in the energy production is considered the primary supply).
Renewables Information - World Table
- Selected Renewables Indicators by Country
This table presents for every country and regional aggregate the main indicators on renewable energy such as TPES, percentage of renewables and the shares of the main fuel categories in total renewables.
Supporting information such as list of tables, general notes, country notes, geographical coverage and conversions is supplied in PDF format.
