I think it's genuinely because wind is a pretty mature technology, lighter-than-air turbines notwithstanding. We know what a state-of-the-art turbine costs, what it produces, and we can make a good estimate of its useful life. There's just not much for a capital allocator to do in the wind space. Solar still has startups and experimentation, so there's at least the perception that as a capital allocator it's possible to pick winners.
