The objective of EUROREX was the implementation of an internet web site on renewable energies. Country specific information and data for 30 European countries were collected as part of the project, systematically arranged, updated and extended. The ZEW was responsible for several countries in the EUROREX daten base: Germany, Switzerland, Netherlands and Austria. Specifically the dissemination of information on the development of renewable energies in Germany was made central to the project. This was acieved primarily through the EUROREX newsletter published every two weeks, available for subscription on the internet at www.eurorex.com. Since November 1999 the project and its services are continued on a commercial basis by the project co-ordinator ESD.
