Global Compute Map

Sites. Records are drawn from the publishable facility corpus (4,304 rows), which excludes licensed-vendor rows by definition (94 rows withheld); 72 duplicate records of a campus are counted once, leaving 4,232 sites. Of those, 3,670 render as marks, one per site; 561 have no coordinates, and the map’s filters (duplicate pins on one campus; bare OpenStreetMap records above 70° north) exclude 1. The methodology sets out how a facility enters the corpus.

The world. Equal Earth on the Greenwich meridian, an equal-area projection, so every region keeps its true share of the plate. The whole-world view runs from 74° north to 56° south. Land and coast are Natural Earth 1:10m; past about three times, the plate adds the countries its records sit in and pale land borders from Natural Earth 1:50m, which draws de facto boundaries.

Circles. A circle’s area is proportional to the site’s power, and it keeps its size at every zoom, so sizes compare across views; at the whole-world view it is the size the site’s own record draws. A pale circle is a figure not counted as operating capacity (announced, permitted or under construction; expanding with no operating share recorded; retired; or a build-out figure with no operating plant recorded inside it). Where a record states more power than it operates, a forest circle for the operating figure sits inside the pale one.

Dots. A dot is a site with no power figure, pale where its record is not counted as operating capacity. At the whole-world view, dots that would overlap settle round their recorded position and stay on land, so density builds into dark clusters; a dot can sit up to about 450 km from its record (median about 100 km). Zooming in returns dots to their records. A site with a circle never moves.

Heat. A Gaussian density of the drawn sites on the equal-area plane, with a standard deviation of about 241 km. The lines stand at 0.5, 2 and 8 sites per 10,000 km².

EU grid substations. The layer’s substations come from PyPSA-Eur’s prebuilt network, version 0.6, derived from OpenStreetMap.
