Poland’s Bełchatów, Europe’s largest coal mine, is slated for a transformation into a leisure lake by 2070 under the state-owned utility PGE’s plan. While PGE views the lake as a way to reuse the land, critics argue the project diverts from urgently needed green energy infrastructure that could bring more immediate economic benefits. Local officials emphasize renewable energy would create more jobs and help the area transition economically, while the lake project’s timeline raises concerns in the coal-dependent community.
