About WREN

Get Started Here: Access the Knowledge Base


WREN (Working Together to Resolve Environmental Effects of Wind Energy) was established by the IEA Wind Committee in October 2012 to address environmental issues associated with commercial development of land based and offshore wind energy projects. As the operating agent for WREN, the US leads this effort with support from Pacific Northwest National Laboratory (PNNL), the National Renewable Energy Lab (NREL), and the US Department of Energy's Wind Energy Technologies Office (WETO).


The primary objective of WREN is to facilitate international collaboration and advance global understanding of potential environmental effects of wind energy. To support this effort, WREN Hub has been created to serve as a collaborative outreach and engagement space, and to disseminate knowledge and information, housed on Tethys. While most WREN information and content is publicly accessible, some space is reserved for WREN member nations for collaborative work, under password-protection.

Knowledge Base and Map Viewer

Tethys has collected over 2,200 documents related to the environmental effects of wind energy - offshore and land-based. All documents are available in a table format via the Tethys Knowledge Base and any documents related to a spatial location have also been geotagged and made available on the Tethys Map Viewer (note: this is a subset of the documents available in the Knowledge Base).
