- I fail to see why efficiency improvements and shifts to non-fossil energy
- sources are mutually exclusive. Your slant seems to imply that it is
- necessary to choose one of these approaches, but the use of the words
- "quite independent" shows that this is not the case.
-
- The argument you make above seems empty to me. It's as if you were advocating
- against unleaded gasoline on the grounds that you could always use your
- bicycle. (note for the unsubtle: I advocate bicycles, but am glad of
- unleaded gas for use in those instances where the bicycle is inappropriate.)
