If Texas want to be green, build more nuclear power plants. They just built a new one in Georgia.
They should use the small units that have been touted
over the last few years.
As I understand it, they can be online in a few short
years, not the 10+ years it takes to get the large
plants online.
Whether you want green or just power Nuclear is expensive but the best option for reliable power. I have been impressed with Solar and how well it is doing but as I said it is only as good as the sun is. I don’t know how expensive Natural Gas Power Generation is but if you want them to be on standby then you have to pay them something to just set idle.
