See? This is what I was talking about.
Don't think that the next 20 years are going to be like the 80's, 90's, or 00's --
With 10 cent/KWh electricity, $3 gasoline, etc.
With all this global warming nonsense, plus governments teetering on bankruptcy, there are going to be some major changes to the world as we know it.
So don't compare the cost of solar power with current electricity costs, for example. And don't bet that your disposable income will remain the same for much longer than the next 6 months. Plan for the worst.
