ETDEWEB: An International Information System for Energy Technology Data Exchange


 The Energy Technology Data Exchange (ETDE), formed in 1987, is an international information exchange agreement under the International Energy Agency (IEA) Implementing Agreement structure.  Current member countries (Brazil, Canada, Denmark, Finland, France, Germany, Korea (Rep. of), Mexico, the Netherlands, Norway, Portugal, Spain, Sweden, Switzerland, the United Kingdom, and the United States) provide R&D information to the exchange and enjoy unlimited access to the collection within their borders.  ETDE welcomes new members.

ETDE's mission is to provide governments, industry, and the research community in the member countries with access to the widest range of information on energy research, science and technology and to increase dissemination of the information to developing countries.   ETDE collects and disseminates its information through an ever-growing database of citations to worldwide energy literature. Over 3.6 million of these records are available through ETDE's internet-based system called ETDEWEB.  In addition to the citations (most with English abstracts and subject indexing), more than 140,000 have direct links to downloadable full-text documents, and many, many more have links to sites where the full text may be obtained. 


More detailed subject areas include renewable energy technologies (such as solar, wind, hydro, geothermal, wave, and biomass); hydrogen; fuel cells; energy conservation and efficiency efforts; fossil fuels (including coal, natural gas, and petroleum); nuclear energy (reactors, biomedical, and other applications); basic energy, physics, chemistry and materials research; energy policy; environmental and economic aspects of energy use; and much more.


The database is useful to researchers, policymakers, students, teachers, industry professionals, information specialists, and more.  Some of the known benefits of using the database are:


- Staying abreast of recent developments in various research areas (including some basic sciences)
- Avoiding duplication of research effort and learning from expected and unexpected results
- Jump-starting research at a point further along than anticipated
- Identifying which countries and people are involved in particular research areas
- Understanding how countries deal with energy-related environmental and climate change issues
- Finding approaches to energy use, including policy and economic factors, alternative and renewable energy sources, and conservation aspects


In addition to information from ETDE member countries, the database contains citations published worldwide regarding nuclear, coal, and global climate change information.  This broader coverage comes as a result of cooperation with other international organizations (e.g., IAEA's International Nuclear Information System, the IEA Clean Coal Centre, etc.).  By late 2005, distributed sources of information, including, will also be accessible through ETDEWEB, making an additional 50 million pages of R&D information available through this single website.


One of ETDE's objectives is to grow and diversify the database even further.  Not only does a new country get access to the wealth of knowledge in the database submitted by other members and through other international organizations, but it also gets to share its own research results more widely. 


Membership in ETDE involves both cost- and task-sharing.  Each country contributes financially on an annual basis, where the contribution consists of a base fee plus an additional amount based on the energy R&D expenditures in the country.  Each country is also obligated to ensure that the energy information published within its national borders is provided in a common format for database entry.  Submission of citations with abstracts and accompanying full text of non-copyrighted material is expected.

Contact Information

ETDE is run by an Operating Agent (OA) located at the US Department of Energy's Office of Scientific and Technical Information (OSTI) in Oak Ridge, Tennessee, USA. The OA functions on behalf of the ETDE Executive Committee comprised of delegates from each member country who meet at least annually to review and direct the program.  See for more details about ETDE and its database.
