France offers some great examples of converting oil infrastructure into cleaner geothermal systems.
In Le Teich, Nouvelle Aquitaine, a former oil borehole has been reconverted in the 1980s into a geothermal hot water producer (73°C). Today it supplies 3,000 m2 of hot water for ponds in a fish farm. The use of geothermal energy avoids the emission of the equivalent of 5,000 equivalent tonnes of CO2 to produce a local caviar. Bon appétit!
