Frequently Asked Questions

What is World Wind Turbine Map?

World Wind Turbine Map is a free, interactive map for exploring wind turbines based on OpenStreetMap (OSM) worldwide, merged with several national wind turbine registers for higher accuracy where they're available - see below for the full list of sources.

You can use it to discover turbines and wind farms near a location, explore the global distribution of wind energy, or inspect available turbine attributes such as manufacturer, model, rated power, hub height, rotor diameter, and operator. For more technical work, you can download the turbines currently visible on the map or the complete global dataset in several formats for your own analysis.

Attribute availability and data quality vary by region and by which of these sources a given turbine comes from - see below.

Where does the turbine data come from?

Turbine locations and attributes come from several sources:

• OpenStreetMap (OSM), queried via the Overpass API - the primary source, covering every country worldwide.
• Germany's Marktstammdatenregister (MaStR), the German Federal Network Agency's official register of power-generation units - used only for turbines located in Germany, since it's a more complete and authoritative source there than volunteer-mapped OSM data.
• The United States Wind Turbine Database (USWTDB), a joint product of the USGS, Lawrence Berkeley National Laboratory, and the American Clean Power Association - used only for turbines located in the United States, where its imagery-verified locations and technical specifications are more complete than volunteer-mapped OSM data.
• Sweden's Vindbrukskollen, a joint service of Länsstyrelserna / Energimyndigheten - used only for turbines located in Sweden, where it provides authoritative public-register data including approval/planning status, the official turbine identifier, and the source record's own last-updated timestamp.
• Denmark's Stamdataregister for vindkraftanlæg, Energistyrelsen - used only for turbines located in Denmark, where it provides the Danish Energy Agency's official master-data register for wind turbines, including the official 18-digit GSRN identifier and an operating-vs-decommissioned status signal.
• France's Éolien terrestre, Géorisques register - used only for turbines located in France, where it provides the official public onshore wind turbine register, including permit/operational status and technical dimensions.
• Canada's Canadian Wind Turbine Database (CanWTD), published by Natural Resources Canada / CanmetENERGY-Ottawa - used only for turbines located in Canada, where it provides an official public turbine register with technical dimensions and a simple operating-vs-decommissioned status signal.

When a turbine from one of the national registers above and an OSM turbine represent the same physical wind turbine (matched by location, within about 100 meters), the register record is shown and the matching OSM entry is hidden, since these registers are treated as higher-quality sources than volunteer-mapped OSM data for turbines in their respective countries. Every turbine's information box states which of these sources its data comes from, with a link back to that source's own record - see below.

Turbines is each source's raw record count before deduplication. OpenStreetMap's Turbines shown count is lower because turbines matched to a national register are suppressed there in favor of the register's own record; MaStR, Vindbrukskollen, Energistyrelsen, Géorisques, and CanWTD raw counts also include decommissioned records, which are never shown on the map.

How often is the data updated?

Each data source is checked independently, on its own schedule, so different sources may reflect data from different points in time. The table below shows when each source was last checked for updates.

Combined dataset last built: Thu, 22 Oct 2026 04:49:19 GMT. This is when the individual sources were last merged together and published to the map. It only happens if any source has new data and not necessarily after every check.

How many wind turbines are shown on the map?

The current worldwide dataset shows 479,080 wind turbines that are operating, or assumed to be operating. Most turbines (every OSM-sourced turbine, every USWTDB-sourced turbine, plus any MaStR-sourced one whose status couldn't be determined) carry no regular status information, and are assumed to still be operating unless a source explicitly states otherwise.

The map additionally shows 3,296 approved wind turbines that have been permitted but are not yet built, sourced from Sweden's Vindbrukskollen register.

The map additionally shows 14,842 planned wind turbines that are not yet built, sourced from Germany's MaStR register, France's Géorisques register, and the "under processing" / "under appeal" Vindbrukskollen layers.

In total, 497,218 wind turbines (operating, planned and approved) are shown on the map.

A further 3,565 register-sourced turbines (currently from MaStR, Vindbrukskollen, Energistyrelsen, Géorisques, and CanWTD) are known to be decommissioned and are therefore excluded from the map entirely, along with any OSM entry at the same location.

The total number is also shown at the bottom right of the map. The same panel also shows how many turbines are currently visible in your map view. This number changes as you pan or zoom the map.

Which data is shown on the map?

The map combines every source listed above - OpenStreetMap plus the German, US, Swedish, Danish, French, and Canadian registers - into one dataset, with each real-world turbine shown only once even where multiple sources describe it.

Whichever source a turbine comes from, its information box shows the same standardized set of fields (manufacturer, model, operator, name, rated power, diameter, hub height, and - where available - status), normalized to consistent names and units rather than each source's own raw field names. It also always shows a Source row naming the dataset the shown data comes from, with a link back to that source's own record - and, for a turbine that replaced a matched OSM entry, a further link to that original (now-hidden) OSM entry too.

The sections below list the underlying field(s) each source provides for every attribute, and any source-specific quirks worth knowing.

OpenStreetMap

Sourced from individual node and way features tagged generator:source=wind worldwide. OSM wind-farm relations are used only to fill missing shared metadata for their member turbines; a relation is never displayed as a turbine.

OpenStreetMap features can carry many other tags beyond this list (for example construction dates, data sources, or Wikidata links). Those additional tags are not shown, but they can be viewed directly in OpenStreetMap via the view/edit in OpenStreetMap link.

Germany – MaStR

Germany's official register of power-generation units, maintained by the Bundesnetzagentur (Federal Network Agency). See the Marktstammdatenregister for the full public dataset.

A MaStR-sourced turbine's information box links to its own record at marktstammdatenregister.de using its MaStRNummer (for example SEE911005051808), and - if it replaced a matched OSM entry - to that original OSM entry as well.

Sweden – Vindbrukskollen

Sweden's public wind turbine register, operated jointly by Länsstyrelserna and Energimyndigheten. See Vindbrukskollen for the full public dataset.

A Vindbrukskollen-sourced turbine's information box links to the public vbk.lansstyrelsen.se map application, and - if it replaced a matched OSM entry - to that original OSM entry as well.

Denmark – Energistyrelsen

Denmark's official master-data register for wind turbines, maintained by the Danish Energy Agency (Energistyrelsen). See the Stamdataregister for vindkraftanlæg for the full public dataset.

An Energistyrelsen-sourced turbine's information box links back to the ens.dk dataset listing page, and - if it replaced a matched OSM entry - to that original OSM entry as well.

Canada – CanWTD

Canada's official Canadian Wind Turbine Database, published by Natural Resources Canada / CanmetENERGY-Ottawa on the Government of Canada Open Data portal.

A CanWTD-sourced turbine's information box links back to the public open.canada.ca dataset page, and - if it replaced a matched OSM entry - to that original OSM entry as well. The dataset's own Turbine Identifier is not shown separately because it is not globally unique; the shipped map id instead uses a synthetic CAWTD-prefixed sequential number.

France – Géorisques

France's official onshore wind turbine register, published by Géorisques (a partnership between the French Ministry for Ecological Transition and BRGM). See the Géorisques Éolien terrestre page for the full public dataset.

A Géorisques-sourced turbine's information box links back to the public georisques.gouv.fr dataset page, and - if it replaced a matched OSM entry - to that original OSM entry as well.

United States – USWTDB

The United States' official wind turbine database, a joint product of the USGS, Lawrence Berkeley National Laboratory, and the American Clean Power Association. See the United States Wind Turbine Database for the full public dataset.

A USWTDB-sourced turbine's information box links to that turbine's own record - looked up by its case_id - directly at the USWTDB's public ArcGIS FeatureServer (USWTDB has no per-turbine webpage of its own), and - if it replaced a matched OSM entry - to that original OSM entry as well.

How complete is the dataset?

The Available column above shows what share of all turbines shown on the map (OSM-, MaStR-, USWTDB-, Vindbrukskollen-, Energistyrelsen-, and Géorisques-sourced together) have a value for that attribute. Status is only ever populated for MaStR-, Vindbrukskollen-, Energistyrelsen-, and Géorisques-sourced turbines (see above). If you think you can provide missing information for an OSM-sourced turbine, see below.

Can I share a map view with someone else?

Yes. Use the Share button to create and copy a link to your current map view. Anyone who opens the link will see the same map location, zoom level, and selected map style, whether it's the standard map, satellite imagery, topographic, or minimal view.

You can also share one specific turbine. Select it on the map and use the Share turbine button at the bottom of its information box. The copied link carries that turbine along with the map view, so whoever opens it arrives at the same place with that turbine's information box already open. The Share button described above behaves the same way while an information box is open.

Can I download the turbine data and what can I use it for?

Yes. Use the download button on the map to export either the turbines currently visible in the map view or the complete global dataset.

Exports are available in several formats:

• CSV – universal tabular format for spreadsheets, scripts and data analysis
• Excel (.xlsx) – convenient for viewing, filtering and working with the data in Excel
• GeoJSON – suitable for GIS software, web maps and geographic analysis
• KML – suitable for Google Earth and other GIS applications

Each turbine includes its coordinates and the standardized attributes available for that record, such as manufacturer, model, operator, name, rated power, rotor diameter, hub height, commissioning date and status.

Every turbine also carries a source field identifying the underlying dataset it came from (OpenStreetMap or one of the national registers) and an id containing that source's original record identifier, such as an OSM node/way ID, MaStR MaStRNummer or USWTDB case_id. Where a register-sourced turbine replaces a matched OpenStreetMap entry, the original OSM ID is retained as well, allowing the record to be traced back to its source even if that OSM turbine is no longer displayed on the map.

The exported data can be used for exploration, research, geographic analysis, data-quality checks and visualisation, as well as other applications permitted by the Data Licence & Terms. If you publish, redistribute or build products using the dataset or extracts from it, please also follow the attribution requirements.

The dataset is not a certified turbine register and may be incomplete, inaccurate or outdated. It should not be used as the sole basis for safety-critical, regulatory, contractual, navigation, aviation, investment or operational decisions.

Can I use this data for my own project?

Yes. We merge all of our sources (see above) into a single combined dataset, the "Merged Global Wind Turbine Dataset by ventodyne", which we make available under the Open Database License (ODbL) v1.0. You may use, copy, modify, and share it, including for commercial purposes, subject to the ODbL and a required attribution statement naming ventodyne and every upstream source.

See the Data Licence & Terms for the exact attribution wording you must include, as well as the original licensing terms of each upstream source. The website, its design, application code, data pipeline, and ventodyne branding are not covered by the ODbL or any of these upstream data licences.

If World Wind Turbine Map is useful to you beyond the required data attribution, we also appreciate a link, acknowledgement, or recommendation to others who may benefit from it.

I miss a turbine or found one with incomplete details. How do I fix it?

Check the Source field in the turbine's information box first - how to fix a turbine depends on which source (see above) it comes from.

If the source is OpenStreetMap, use the view/edit in OpenStreetMap link in the information box to open the turbine in OpenStreetMap. There you can update the information yourself, or use OpenStreetMap's community channels if you need help. Once an edit is published in OSM, it should appear here after OSM's next refresh (see above for the current schedule).

If the source is one of the national registers (see above for the current list), this map cannot accept corrections directly - it only shows a periodic snapshot of that register. Use the link to the source's own record in the information box to check the original data, and follow that register's own channels for reporting an error there. Any correction made at the source will appear here after that register's next refresh (see above).

Is the turbine data accurate and complete?

The map is designed to make wind turbine data from OpenStreetMap and several national registers (see above) easy to explore, but coverage, positional accuracy, and attribute completeness vary by location and by source. Data can be incomplete, outdated, incorrectly tagged, or contain errors.

Do not use this map or its exports as the sole basis for safety-critical, regulatory, contractual, navigation, aviation, investment, or operational decisions. Verify important information against authoritative sources.

How can I support this project?

World Wind Turbine Map is free to use and is built on data contributed by the OpenStreetMap community, merged with several national wind turbine registers (see above). There are several ways you can help:

• Improve OpenStreetMap data: If you find a missing turbine, an incorrect location, or incomplete turbine details on a turbine whose Source is OpenStreetMap, select it on the map and use the view/edit in OpenStreetMap link. Adding or improving information in OpenStreetMap benefits this map and other projects that use OSM data. Turbines sourced from one of the national registers are typically not community-editable this way - see above.
• Share the map: Send a map-view link to colleagues, friends, researchers, or anyone interested in wind energy. The share button preserves the current location, zoom level, and selected base map.
• Acknowledge the tool: If World Wind Turbine Map or its data export is useful in your work, publication, presentation, or project, we appreciate a link or acknowledgement to World Wind Turbine Map.
• Recommend it: Mention the map to people who may find it useful, such as wind-energy professionals, researchers, educators, mapping communities, and travellers.

When you reuse OpenStreetMap data, please also comply with the applicable OpenStreetMap attribution and ODbL requirements.
