# Energy Technology Data Exchange

The Energy Technology Data Exchange (ETDE) was formed in 1987 and officially ended 30 June 2014. It was initiated as a multilateral agreement under the International Energy Agency (IEA) agreement network, replacing numerous other bilateral agreements. The multilateral agreement was for the international exchange of energy research and development and information. The exchange resulted in a database which was the world's largest collection of energy research, technology, and development (RTD) information (ETDEWEB - described below). The collection of information was generated from energy RTD literature published in member countries and through other partnering arrangements with organizations such as the International Nuclear Information System (a unit of the International Atomic Energy Agency). This had the effect of creating a broad spectrum of information that was included in the ETDE database. The range of content included fossil fuels, renewable energies (including Hydrogen), End-Use (Buildings, Industry and Transport), fusion, energy policy, conservation, and efficiency, and cross-sectional activities. This fulfilled the need for timely exchange of global information towards the goal of a sustainable energy future. ETDE operated under an IEA Implementing Agreement and was governed by an Executive Committee of delegates from ETDE member countries. Officers of the Executive Committee included a Chair and two Vice-Chairs, elected to three-year terms. Day-to-day operations were managed through an operating agent organization, which reported to the Executive Committee.

## Energy Database

ETDE's Energy Database was a substantial collection that focused on energy research literature and technology literature. This database contained more than 4.5 million abstracted and indexed records, and was updated twice per month. Temporal coverage was from 1974 to 2014. The principle access point for this database was ETDEWEB (see next section). However, access was also available through commercial online hosts, and some countries offered their own products for access. Member country representatives supplied the best options for their citizens to access this database. Furthermore, the United States fed this database to Dialog which provided online access. Likewise, Germany fed this database to STN International.
Broad subject coverage included information on energy research and development; energy policy and planning; basic sciences (e.g., physics, chemistry and biomedical) and materials research; the environmental impact of energy production and use, including climate change; energy conservation; nuclear (e.g., reactors, isotopes, waste management); coal and fossil fuels; and renewable energy technologies (e.g., solar energy, wind energy, biomass, geothermal, hydro). The scope of topical coverage was worldwide in some areas. The database was used by scientists, researchers, engineers, policymakers, information specialists, librarians, industry leaders, university faculty, and university students, among others.

## ETDEWEB

Energy Technology Data Exchange employed an internet related database to disseminate the energy research and technology information which was collected and exchanged. The database was named ETDE World Energy Base or ETDEWEB.
ETDEWEB was produced and made available by ETDE. It had over 5 million references for literature that encompassed broad topical coverage, and allowed access to more than 500 000 full text documents and reports, which amounted to more than 1 million pages. ETDEWEB had unique access to these reports, which were often not available through other conventional sources. Over a million other references linked to sites containing cited documents. Open access was provided to member countries, countries with developing country status, or by Executive Committee decision.
Online access was extended through the wordwideenergy.org website.

### WorldWideENERGY.org (WWE)

After the previous ETDE consortium ended in 2014, the WWE application allowed ETDEWEB and other content to remain accessible, thanks to remaining funds and former member country support. But this extended access also ended in July 2016. There may be a possibility that ETDEWEB will again become accessible at some unspecified time in the future via the US DOE’s Office of Scientific and Technical Information (OSTI) systems.

### Subject coverage

ETDEWEB covered an extensive base of topics, the main areas included information on energy research and development along with energy policy and planning. Other areas of coverage included basic sciences (e.g., physics, chemistry and biomedical); materials research; the environmental impacts of energy production and use (including climate change); energy conservation; nuclear energy (e.g., reactors, isotopes, and nuclear waste management); coal and fossil fuels; and renewable energy technologies (e.g., solar, wind, biomass, geothermal, hydro).
