Home Improvement - Solar Panels or Insulation

The other day, I met an interesting fellow who told me that he was environmentalist and that it was too late, the Earth was doomed, and all the people on the planet were nothing more than lice on top of someone's head. That's an unfortunate way to look at humans, and I suppose if you look at some of the worst polluted areas on the planet you might agree. Personally, I don't see it that way, but he sure did. In fact he told me that there should be solar panels on every house by now. That is something I also disagree with. Okay so let's talk shall we?
You might be asking yourself why anyone would, especially someone who runs a think tank, believe that we wouldn't be better off with solar panels on top of every house. Well, the way I see it, we would get more bang for our buck would if we used the most efficient methodologies. Sometimes it makes sense to have centralized electricity production, and sometimes it makes sense to have a more distributed approach. Philosophically these are different ways of looking at things. In my opinion it makes sense to do both where it is feasible, and efficient based on mathematical metrics.
It doesn't make sense to put solar panels on top of every home, as some homes have trees in front of them or behind them shading certain parts of the roof also, not every portion of your roof is facing towards the sun. Further, the efficiency of today's solar panels isn't quite as good as it needs to be.
You might think otherwise, but the reality is solar panels are already 50% inefficient before they start, this simply because the sun does not shine at night.
Therefore, when people say that solar panels are 25% efficient, which right now is a very high efficiency rating, what they're really saying is they are 12.5% efficient, which is not sustainable, and it isn't efficient, especially for the cost. Now, you might get a tax break if you put up solar panels, but you are taking money away from the government which could use it for something else. Something like education, police and fire, military, or social services.
It might be wiser to do the inexpensive things first such as insulation, making your home 20% more efficient, meaning you will use less energy. After all if this is just a mathematical equation if you save 20% energy, that's probably better overall than having to produce 20% more. You see the point? Personally, I don't think we should put solar panels on every house and home in America, but it might make sense to put them on warehouse buildings, schools, and places where we get maximum benefit.
Further, it might be better to wait until we have improved the efficiency of solar panels, which we will do with the next generation, or perhaps the following generation of technology after that. Maybe it makes sense to wait from a cost and efficiency standpoint that is.
Therefore I disagree with the environmentalists who wish to push solar panel technology onto the public because they somehow believe that's the way to go. Mathematically, I can prove them wrong, even if their words do sound all warm and fuzzy and the right thing to do in their minds. Please consider all this and think on it.
