Huh? Solar is widely acknowledged to be significantly cheaper than building new coal. And it is everywhere, you can just buy containers of it and have it delivered anywhere in the world.
Have you paid attention to anything since 2020? Are you paying attention to anything now?
Suggesting PV is "cheaper" because of the per-watt cost to install it misses so much reality it's hard to take seriously. We live in the now, not some idealized future state. We need energy NOW. Do you think solar cells are immune to supply and demand? And that the economics will not be affected by a global shift?
