Built this over a weekend to experiment with AI-assisted coding.

Data comes directly from Germany's official energy registry (Marktstammdatenregister / MaStR) — 40,500 wind turbines with real GPS coordinates, capacity, manufacturer, hub height, and commissioning date.

Technical details: - The bulk export is a 2.8GB ZIP. Instead of downloading it all, I used HTTP range requests to read the ZIP central directory (42KB), locate EinheitenWind.xml, and download only that file (7.5MB compressed → 184MB XML)

  - Rendered with deck.gl + MapLibre (CartoDB dark tiles, no API key needed)

The EEG layer is what surprised me most: 9,247 turbines have already lost Germany's 20-year wind energy subsidy. Another 3,094 expire by 2028 — those are the repowering candidates.

Happy to answer questions about the data pipeline or rendering approach.

Very cool! How hard would it be to add all the solar installations? They must be in the register as well
