- The studies that were mentioned for the high and medium case were
- created just for that purpose. Since all of the results of these
- studies were not detailed, I am not sure how the mix was seen to
- vary over time, but CO2 emissions were provided for each case
- without being modified for nuclear or efficiency strategies.

- I would agree that growth models for future decades are shaky, but they
- are all that is available, outside of intuition, for policy-makers.
- The study said "effectiveness" and I interpreted this to mean energy
- intensity as a function of GNP, but you may be right. There is a
- UCS/NRDC study that makes aggregate cost estimates for a variety of
- energy scenarios. Which externalized costs are you referring to?

- These studies were for electricity, so unless ZEV's become popular (and
- I am not aware of any such assumption), it is a different issue.
