It's still not earning you money to spend electricity because you still have to pay the transfer fee which is around 6 cents / kWh but it's pretty damn cheap nevertheless, mostly because of the excess in wind energy.
Last winter because of a mistake it dropped down to negative 50 cents / kWh for few hours, averaging negative 20 cents for the entire day. People were literally earning money by spending electricity. Some were running electric heaters outside in the middle of the winter.
I can assure you the same is true for fossil fuels in Texas right now, so I don't see how this is a strike on renewable energy
I heard only shale gas but good to know about oil. As far as I know, USA is not one of the main oil exporters, mostly middle east countries, especially of Arab peninsula. Venezuela, Iran, too but they are under sanctions. American oil / gas, please, correct me if I am wrong serves mostly as strategic reserves so it may be that USA that it's better for Texas to use solar energy. However, most of calculations don't track the whole lifecycle of solar panels and their environment conditions - I mean whole energy produced for the solar panels lifespan (15 - 25 years) minus the costs of production and utilization. The analysis needs to be done per each case not mandated for all because it doesn't make sense with the total costs adjusted like in Poland. I know many owners of solar panels in Poland and it's not that 'rosy' with the solar energy savings
To be honest, I'm struggling to keep track of the points you are making because you brought in several tangential topics all at once without much context (shale gas vs. oil, oil exports, LCOE, Poland all in a thread about solar energy in Finland compared to fossil fuel energy in Texas). I'll just point out that the US is #4 in oil exports, by either barrels or export value (source: https://en.m.wikipedia.org/wiki/List_of_countries_by_oil_exports) and the number one oil producer (source: https://en.m.wikipedia.org/wiki/List_of_countries_by_oil_production), so I think it is pretty obvious that the investments into fossil fuel infrastructure in the US are well and above what is necessary for a "strategic reserve" use case
It brought it up because I know that most these analysis are just misleading at best. Once again, I know exact numbers for Poland and these are very, very poor. It's beyond my surprise that somebody says that in Finland where they have polar days and nights and almost in arctic circle (the strongest sun radiation is on equator), its energy effectiveness balance could be positive. Nobody has provided numbers so far

We shall see only then how the solar panels market develops without subsidies. It can't be done without energy storage which will be beyond expensive (which is the most cases for now) and power networks / providers don't want to buy the energy back. That's the current state in Poland - I know, my father has solar panels
The US is the world's largest oil producer. The US, however, does not export the most crude oil, but instead exports large quantities of refined products (gasoline, diesel, etc.).
The US was the largest exporter of liquefied natural gas in 2023.
