A quick history of the lists

Originally, these email lists were hosted at CREST (the Center for Renewable and Sustainable Technology). Founded in 1993 CREST focused on renewable energy, energy efficiency, the environment, and sustainable development, which included these email lists, and ftp, gopher site and Mosaic server called the Energy Source. Later the lists were hosted by the Renewable Energy Policy Project (REPP) at with online copies of the email lists, and additional resources on web sites and via ftp.

Tom Miles has provided web hosting and technical support for the bioenergy web sites at since 2004 and assumed responsibility for hosting the mailing lists in 2010.
