I'm not up to date on current industrial-scale solar cell manufacturing processes, but doesn't the manufacturing proccess still require massive amounts of coal? And what is the lifespan of the cells before they have to be replaced with new cells that also require coal to be produced?

On the battery side, I'm pretty sure that industrial-scale production still requires mining and mountain top removal. And what are wind turbines made out of? Where are we getting those resources from?

Like I said, I'm not up to date on the state-of-the-art industrial manufacturing processes required to make solar cells / turbines. But I'm pretty sure it will still require massive habitat destruction and the release of unimaginable amounts of greenhouse gasses to get us where we need to be.
