one fact u miss is that the more solar panel s, are made , then u can

the electricity from these panels to produce more, , which can be made

It's not free. The "cost" equals the energy used to produce, install,
maintain, repair and replace the panels. It all has to be paid for...

The point is, that every factual calculation I have seen shows that
there is a net loss in energy. -On average-, it costs more energy than it
produces. I wish it didn't.

So the energy to make new panels isn't free, making the energy they make
"not free". It's a cycle with a friction load. It must wind down.

Until the energy cost of production decreases and the efficiency of the
panels increase, it doesn't seem to pay.

At this point, GMO fermentation of cellulose seems the best choice for
automobile fuel if you want to replace oil.
