My point was that it makes more sense to compare total lifetime operational costs, rather than just capital costs. Dollar cost of buying fuel is one operational cost. Impact of CO2 emitted is another possible operational cost.Good, then stop adding it to every PV thread and I won't call you out on it.
While you may believe that the impact of CO2 emitted is zero, many others put a different cost on it. Since there's disagreement, we could perhaps come up with a cost/benefit analysis in which cost of CO2 is a parameter, so you get a whole family of answers depending on that parameter. Or we could poll people and take the median answer, or maybe the mode, or maybe the average after throwing out outliers, or whatever. As uncertainty of cost is not unique to CO2, there may be other standard methods or practices for dealing with uncertainty that I'm not aware of.
Anyway, the possible cost of CO2 belongs in a cost/benefit analysis, which is where the thread went, rather than the technical issues originally raised.
