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

15
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

16
Limitations of Deep Geothermal

• Energy produced is non-transportable
• Project development requires significant upfront
  investment
• Timing of development schedule

17
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
