Nuclear Intensive Scenarios
•Scenarios by difference:P.A.BauquisD.Heuer and E.Merle
•Objective oriented ScenariosH.Nifenecker et al.

No miracle from renewables•Hydro:
Limitation of ressource (Europe-USA)Environment and localization (Am.Sud, Asie, Afrique, Russie)Large Investments Reliable, availableMight provide 20% of world electricity.
France: 70TWh/450•Wind
« fatal » EnergyLimit: 10-15% of electricity production

No miracle with renewables
•Solar
PV: Ideal for isolated sites (Africa, SE Asia). Mostly artificial in Developed Countries and very expansive
Thermal: interesting for heating and warm water
Thermodynamic: Fiability? Hot and dry climates Hot and dry climate.
•Biomass
Bio-fuels (10 Mtep/50)
Wood energy.
Competition with food, energy and environmental balance
