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, Tethys was expanded to serve as a collaborative outreach and engagement space, and to disseminate knowledge and information. While most WREN information and content is publicly accessible, some space is reserved for WREN member nations for collaborative work, under password-protection.

WREN White Papers
WREN is producing a series of white papers that address common problems facing wind and wildlife interactions, for which solutions are often elusive, and that do not fall within the purviews of industry, regulators, or researchers. The list of white papers is available below. As each paper is produced, it will be made available on Tethys. Each white paper is also summarized into a 2-page fact sheet, also available on Tethys. The summaries are translated into additional languages, representing the WREN network.
WREN White Papers:
Individual to Populations (expected in 2017)
Cumulative Effects Assessment (expected in 2018)
Green versus Green (expected in 2018)
Risk-Based Environmental Management (expected in 2019)
Tethys Fact Sheet
To highlight Tethys content, key functions, use of the site, and growth, a fact sheet with a summary and assessment of Tethys over the past 4 years, 2012 to 2016, was created.
WREN Short Science Summaries
WREN seeks to summarize the current state of the science on interactions between wind energy development (land-based and offshore) and wildlife. A series of short science summaries are being prepared and made available for download on Tethys:
WREN hosts quarterly webinars on the environmental concerns that are of importance to the land-based and offshore wind energy industries, as a means to effectively disseminate new information and research efforts to a large international audience of stakeholders.
Presentations from past wind energy webinars are hosted on Tethys, along with the associated video, as well as questions and answers. Visit the archive.
Knowledge Base and Map Viewer
Tethys has collected over 2,400 documents related to the environmental effects of wind energy (land-based and offshore). All documents are available in a table format via the Tethys Knowledge Base, which can be easily filtered to find documents relevant to specific searches such as document type, technology type, or environmental effect. Any documents related to a spatial location have been geotagged and made available on the Tethys Map Viewer (note: the Map Viewer contains only a subset of the documents available in the Knowledge Base).
As an international initiative with 11 countries participating, in-person meetings among WREN country representatives are an important aspect as we work together to achieve the goals of WREN. These meetings occur twice a year, often in conjunction with related international conferences. The following is a list of all WREN meetings – both past and upcoming:
