One has to consider why the cost is dropping... which has a lot to do with manufacturing in China. I don't take it as a given that in the geopolitical turmoil that seems to be developing, and the trend to deglobalisation, that the prices will continue to fall, or even remain stable. The other aspect of this is that after Europe's recent experience everyone is likely to get much more paranoid about energy securtiy and redundant capacity, which will also affect uptake of renewables. It is also not clear to me that the same driving forces in the West will apply to the big fossil fuel consumers of the next 50 years, India and China. But it doesn't matter I guess, if renewables are cheaper they will win whatever someone thinks.
