This is a far from the truth as a I can imagine. There are still a large number of wind and solar projects in progress and I don’t believe the cadence has changed.
The reason here is it makes no sense for what they are trying to do. They want to power a DC, the sun sets and wind comes and goes. You would need overcapacity on both and then batteries. Probably something in there with not wanting to connect to the grid.
Wind and solar would require lots of land next to the DC to guarantee power.
Your statements are borderline lies. Texas gets a lot wrong but it is still building out lots of solar and wind but neither of those power and onsite DC very well.
Trump paid a wind farm company $1,200,000,000 of taxpayer money to stop building a wind farm
What if..... the USA had a national grid and what if.... they connected solar and wind across the country and for kicks, invested in storage.
