| Abstract |
The Geothermal Trend Report, an annual publication by the International Energy Agency Geothermal Technical Collaboration Programme (IEA Geothermal), provides an overview of geothermal energy statistics in member countries. The work for this report is accomplished within Working Group 10 - Data Collection and Information. The main objective of this working group is to collect data on geothermal energy uses, trends and developments in member countries in a standardised way, and to publish these data in a brief report on a yearly basis. Data collection within the IEA Geothermal covers topics from specifications on geothermal power generation and heat uses, CO2- and energy savings by geothermal energy uses as well as project highlights. All IEA Geothermal member countries are required to support the work on the Trend Report by providing information. Additional data from sources such as publications associated with the World Geothermal Congress and the IEA Geothermal Annual Reports have been compiled and analysed to show trends in geothermal energy uses in member countries from the year 2000 on. Based on the results of the first data collection, which started in 2011, and publication reviews, the Report Trends in Geothermal Applications - Survey report on geothermal utilization and power development in GIA member countries in 2010 with trends in geothermal power generation and heat uses, in short the Geothermal Trend Report, was published in 2012. Thus, in the year of the World Geothermal Congress 2020, the work on geothermal energy statistics within IEA Geothermal has been running since 10 years. During this time there have been several changes in the approach of data collection. Among other things data collection was adapted to the one of the International Energy Agency in order to make geothermal statistics of different organisations more comparable. Overall, the IEA Geothermal Trend Report adds substantial information on geothermal energy use on an international scale and helps to point out trends and market developments. Due to the fact that data on geothermal power generation is easier to access – compared to information on direct use applications and ground source heat pump data – IEA Geothermal decided to prepare a separate Power Report (IEA Geothermal Power Statistics) and publish this earlier in the year.
