Paris Basin, France • 34 district heating projects since 1969 • Thermal capacity equivalent to 308 MW • Provides heating for over 150,000 units • Over 250,000 tonnes of CO2 emissions avoided
Benefits From Using Geothermal Energy • Available for the long-term • Near zero greenhouse gas emissions • Sustainable • Reliable • Not subject to significant price volatility • Can be integrated with existing infrastructure
Limitations of Deep Geothermal • Energy produced is non-transportable • Project development requires significant upfront investment • Timing of development schedule
Potential Uses of Geothermal Energy • Heating buildings in new industrial park developments • Heating homes in new residential subdivisions • Retrofitting commercial buildings • Pre-heating industrial boiler or process water • Drying ethanol plant distillers grain • Tourism • Greenhouses • Electricity generation
