About WREN | Tethys

Wind Energy-Environmental Research & Engagement Network (WREN)

WREN (Wind Energy-Environmental Research & Engagement Network), also known as Task 59 (formerly Task 34), was established by the International Energy Agency (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 United States (US) leads this effort with support from the National Renewable Energy Laboratory (NREL), the Pacific Northwest National Laboratory (PNNL), and the US Department of Energy's (DOE) 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 & Publications

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 purview 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. The following are completed or planned:

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:

Wind Monitoring and Mitigation Technologies Tool

As part of its mission to support the global deployment of wind energy through a better understanding of environmental issues, WREN has created a free, online Wind Monitoring and Mitigation Technologies Tool to catalog technologies that assess and reduce potential wildlife impacts resulting from land-based and offshore wind energy development. WREN will continuously maintain and update the research status of technologies to ensure the international community has access to current, publicly available information on monitoring and mitigation solutions, their state of development, and related research on their effectiveness.

Offshore Wind Metadata

WREN partnered with the Tethys team to create a catalog of environmental monitoring at offshore wind project sites around the world. Each offshore wind farm lists a description, timeline, characterization of the environment, environmental monitoring reports, monitoring data, and details on monitoring conducted during baseline, construction, operation, and decommissioning. Information is vetted by project developers, when possible, and will be updated on an annual basis.

WREN Webinars

WREN hosts 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. You can sign up to receive invitations to webinars here.

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 3,600 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).

Wind Energy in Latin America (Energía Eólica en Latinoamérica)

WREN launched a Wind Energy in Latin America (Energía Eólica en Latinoamérica) page on Tethys that highlights literature and resources focused on wind energy in Latin America, including WREN short science summaries and other documents available in Spanish.

History of WREN

WREN began in 2012 and currently within its fourth phase, as summarized below.

Loading Data...

Phase 1: 2012-2016

The goal of WREN is to facilitate international collaboration that advances global understanding of environmental effects of offshore and land-based wind energy development, though the formation of a community of practice around research, monitoring and management of the environmental effects of wind energy development. Two key products were developed during phase 1: 1) Tethys was expanded to include land-based wind and host WREN activities and 2) a white paper focused on adaptive management.

Partner Nations (7):

Phase 2: 2016-2020

The second phase of WREN included the expansion of Tethys, development of several white papers, continuation of the webinar series, and outreach and engagement efforts. All these activities were aimed at contributing to supporting the expansion of land-based and offshore wind energy deployment.

Partner Nations (10):

Phase 3: 2020-2024

The objective for the third phase of WREN is to assess the global state of the science related to the environmental effects of both offshore and land-based wind energy development. Over the course of the third phase, WREN will: (1) Identify priority international needs for further research related to the environmental effects of wind energy development; (2) Aggregate, synthesize, and disseminate information on the global state of the science on high-priority issues and recommended practices within the wind energy industry; and (3) Assess the technical readiness and effectiveness of solutions and explore the feasibility of transferring technologies and methodologies among jurisdictions.
