I realize I'm an outlier -- but I'm not fond of solar. Though when I was younger, I was an enthusiastic supporter. But now I realize that a 30 year life-span for solar panels means that there will be a huge recurring cost associated with solar. That is a huge cost to our society. And the more we use solar then the larger that cost will be. In contrast, Wind Turbines and their blades can be repaired and continue to work for much longer. On top of that, I understand that in some countries there are neighborhoods who share ownership of wind turbines - largely eliminating the Big Utility middleman who might extort profit (as is so common here in the United States.) The role of the utility becomes power transmission rather than monopoly sourcing of energy.
