I was just pointing out what I perceive to be a problem in the way we evaluate alternative energy in relation to fossil fuel energy.  I don't presume to be smart enough to know what the solution is:-)
At some point in an individual's thinking on the cost/benefit ratio of alternative energy systems, and, at some point in the whole industry's thinking, the question will change from (for example): what is the cost in $/kwh for on grid electricity vs PV electricity, to: what is the cost of no electricity vs the cost of PV electricity.
Many individuals have reached this point. I think the industry as a whole is pretty far from this point.
