A counterpoint is that wind and solar are impossible to defend in a conflict (especially off-shore wind), and can be irretrievably wrecked with minimal risk to the attacking force. I don't think this should be any sort of impediment to putting renewables everywhere we can though. If there is a war big enough that countries are destroying each other's energy infrastructure we'll almost all be dead anyway. Nuclear winters will kill solar production (and also most of the demand, I guess).
