6. Conclusion
Disadvantages
Limited quantity of natural gas
To be fully consumed by
2070
Higher operating cost
Highly inflammable
substance
- a colorless and an odorless substance, detection of gas leaks can be difficult- The process of extraction of natural gas involves making large cavities in the
ground. The cavities result in an increase in soil pressure and can cause the ground to sink
- Natural gas occupies four times the space of a gasoline-equivalent energy
Transport is costly

FItaly : 40%
England, Spain,
Austria : 35%
French objective :
- To modernize production’s park of electricity- Since 2009 : Project to built every CCPP- In order to reduce waste and CO2 emissions- There will be 10 CCPP by 2012- Three of them are currently being built
