Welcome to ETDEWEB World Energy Base (or more simply, ETDEWEB) where you can search and explore literature references and many full text documents not typically available through conventional sources. ETDEWEB is no longer being fully supported as of mid-2014, and there are no new records being added. The non-United States ETDEWEB content is made available by DOE's Office of Scientific and Technical Information in honor of the many devoted delegates and partners who shared energy-related content for over 25 years. The United States content contributed to ETDEWEB also continues to be available, but it is included in the whole US collection information (including newer information) at https://www.osti.gov. ETDEWEB was produced by the member countries and partners of the Energy Technology Data Exchange (ETDE), which was an international agreement under the International Energy Agency (IEA) framework from January 1987 - June 2014.
