Paris Geothermal Boom Brings Deep Drilling to Crowded Suburbs

Squashed between a highway overpass and a towering suburban shopping center east of Paris, a drilling rig is completing the second of two geothermal wells aimed at capturing the earth’s natural heat for homes and offices.

The project is one of five around the French capital being built by Engie, the new name for GDF Suez SA, accelerating a geothermal boom in the region. Greater Paris already boasted the world’s largest concentration of deep geothermal wells linked to heating networks, even before these latest additions. An energy law making its way through the French parliament that seeks to spur rewewable energy could lead to more.
