Case study | Aéroport de Paris – Orly |
Description | Faithful to the commitments made at the Grenelle Environment Forum in 2007, Aéroports de Paris creates a geothermal power plant for heating its buildings. Two wells are dug in The Dogger, a 1.8 km depth aquifer. The water comes up at 74°C. Geothermal energy reduces carbon dioxide emission of 9000 tonnes each year. |
