Current generations of solar cells consume more BTUs of fossil fuel energy to manufacture than they produce in BTU’s over their entire life span if they make it the full 20 years at full rated performance -which, of course, they don't.

By front loading the burning of fossil fuels they actually radically INCREASE the amount of CO2 emitted into the atmosphere

And that’s from 1997... Cell costs are far lower today than they were then while at the same time electricity isn’t cheaper.

If what you say were true the solar cell companies would be essentially selling the cells at a loss due to the energy consumed to manufacture them. And they would never pay for themselves - which they easily do in less than 10 years these days. You also neglect to mention that you lose substantial energy converting fossil fuel BTU’s into electrical BTU’s. And electricity is the goal.

And as far as CO2 goes, I could care a less about CO2 output one way or the other.
