Really? Over recorded history, people have an awful track record of predicting the future, good or bad. Economists are some of the worst. I seriously doubt that any significant number of people will disconnect from the grid even in the lifetime of my kids. Sure, will some people reduce their consumption with solar PV (which by the way has a horrible ROI especially when you factor in the cost of money), but only the most die-hard folks will disconnect completely. What was it you were selling again? I didn't bother to read the rest after being so distracted by the introduction.
