Lets address your claims line by lines
>It's not that solar cannot scale as is, it simply cannot scale as a power grid
Grid forming inverters have solved all your claims
>Solar is cheap if you only look at the panels and how much energy it produces. It is not cheap if you look at the whole grid, which is something omitted from reports you see.
This is untrue, the math conclusively proves your claims wrong, the solar industry produces a KWH for cheaper than any other source.
All the costs from harvesting raw material, making solar panels from raw material, building batteries, building grid forming inverters etc... are all captured. In the final cost in how much that producer sells a KWH for
Companies that operate solar panels and sell the KWH produced are able to undercut all other power generation companies using other methods.
Fossil fuels are massively subsidized compared to solar companies
Fossil fuels are subsidized by public transportation infrastructure to move their fossil fuels, special tax writeoffs, get to lease land that has oil for dirt cheap from the government. They also get special payments from the government even when they don't produce power, IMF data also shows far more direct subsidies.
Furthermore the trillions we spent on the Iraq war, and now the Iran war are being subsidized by the government that aren't being reflected in the price per KWH of a operator selling KWH generated by fossil fuels (If the oil companies had to use their own profits to pay for war). Oil companies also don't have to pay for negative externalities for exhaust fumes, and dumping waste into the water.
>Relying on China for panels & batteries for energy security?
China cannot cut off panels and batteries, these are commodities, these things are produced and sold in such large numbers that there is no possible way to track down or monitor such information.
These are not Jet Engines, nuclear centrifuges, advanced military microchips, Lithography machines, Rare Earth
There are only a handful of companies that buy rare earth, they are low volume, highly specialized (Hence possible to cut off)
While there are 1,000,000x more companies that buy their panels and inverters from china. Every single gas station, Every single convenience store, Every single grocery store, Every walmart, Every mcdonalds, Every auto repair shop, Every corporate building, Every one with a parking lot etc... would be a potential customer to buy solar panels, and batteries and install their system themselves.
They can cut off Rare Earth because theres a handful of companies in the US that can actually use them. While there are millions of companies in the US buying batteries and/or solar panels.
Once a ship leaves with 50,000 panels theres no tracking them. BTW China produces 1 billion solar panels a year!
