Well, let's compare France and Germany. Their per capita emissions should be identical except for power generation.
France: 6.80t of CO2 per capita (about 90 % CO2 free power) Germany: 10.21t of CO2/capita (about 33 % CO2 free power)
And this in spite of a higher French per capita power consumption!
So power the kind of power generation utilized is obviously one of the most, if not the most , important factor for CO2 emissions. And it is more important in what way the power is generated than what how much power is consumed. Peak oil is not an energy crisis. It is a liquid fuel crisis.
If Germany abandons its nuclear plants, its carbon production will rise.
The effect in botanical terms alone is much greater than had been previously thought:
