I really love the used blade issue! Life expectancy quoted as 20 years. Real world experience is 8 to 9 years before replacing. Well that doubles the costs of blades! Oh and there really is no way to recycle them, so they are dumped in a land fill.... that’s Greens for you..... more latte for you?
In my opinion, there are “potential” ways to use solar energy to provide a major component of society’s energy needs. None of the current conversion/storage approaches seem feasible to me on a society-wide basis.
The BIG problem is that our overlords have chosen the ‘winner’ already and sounder approaches to the problem will not be given a chance. The dead horses of wind turbines and solar panels will be flogged to generate profits for the few while leaving most of us in actual danger from disastrous outages.
