I was wondering how long it would be before someone would try to make that sort of analogy... (And I am of course prepared for it...40 years ago, I wonder what the projections were for the percentage of families in the economically developed world which would own a "personal computer"? (Or a "mobile telephone"?)
Here's the problem with comparing solar power to technological gadgets like computers and cell phones, (or televisions or radios)
If you want what a computer can provide, there is no alternative to having a computer....if you wanted Uncle Miltie in your living room every Tuesday night, there was no alternative to having a television....
If you want what solar power provides, (ie, energy) there are numerous alternatives....
There simply is not the sort of "monopoly of need-meeting" in the case of solar power that drove the demand which led to the economies of scale for major technological devices that enabled their rapid expansion in our society.
