Carbon Free Power Production by 2050

Is that self sufficient, or by governmeant subsidies.

And manufacturing the solar power panels, is that green?

I'm all for cheaper greener power, but with solar, are we there yet? I mean Really there or does it need to be subsidized.

Subsidies affect the cost, but not the energy payback. The energy it takes to manufacture the solar panel is the same regardless of who pays.

There are two price breaks. One is where installing solar panels on your home saves you money that you would have paid to the energy company. We are way past that point. The other is for energy companies to produce energy more cheaply using solar panels than with other sources. We are pretty close to that, or may be past it, depending on region and on the company.

I don't know about how green solar cell manufacturing is.
