GRID · WIND FARMS
The Renewables Build-Out
Wind is the fastest-growing slice of the world’s generation fleet, and this layer maps where it actually sits: 11,211wind farms from OpenStreetMap, drawn as radar-green turbines and sized by capacity — from a single community turbine to the great North Sea arrays like Hornsea and Dogger Bank. The biggest farms anchor the world view and the smaller ones reveal as you zoom in, so the map shows the giants first and never dissolves into clutter. Tap any turbine for its name and capacity. Capacity is mapped on about 81%of farms — the rest draw at the smallest size rather than invent a number.
The biggest farms
The giants are overwhelmingly offshore, where turbines can be bigger and packed into open sea: the North Sea arrays — Hornsea, Dogger Bank, Sofia — lead the world, alongside the big onshore complexes in India (Muppandal) and the US (SunZia). These are the largest singlefarms as tagged in OpenStreetMap; a few aggregated “wind bases” (China’s Gansu base runs to roughly 10 GW) and the odd mis-tag are held out of this list so it reads true.
Where the farms are mapped
Read this as a map of where wind farms are mapped, not where wind power is. About 70%of the farms here sit in Europe — not because Europe has most of the world’s wind, but because OpenStreetMap is mapped most completely there. China is the largest wind market on Earth and India is in the top five, yet both are thinly tagged as wind plantsin OSM, so they look far smaller here than they really are. The shape of the data is the shape of the mapping — a caveat worth carrying on every OSM-based layer.
About this data
Every farm comes from OpenStreetMap (power=plant with plant:source=wind, via the Overpass API, ODbL). OSM also holds over 460,000 individual turbines, far too many to draw at world scale — so this layer maps the 11,211 wind farms, the “where wind power is” story. Capacity (the plant:output:electricity tag) is recorded on about 81% of them (9,115 farms), so capacitysets the size; it’s drawn on a square-root scale and capped so a single mis-tag — a German “park” tagged at 5,755 MW, say — can’t paint a monster turbine, and farms with no capacity tag draw at the smallest size rather than a fabricated one. Operators are never shown. Coverage follows OSM mapping completeness, which leans heavily to Europe, so this is the publicly mapped fleet, not a complete census. Snapshot taken 2026-06-26.
