Texas has 100GW of solar and 50GW of batteries in ERCOT’s interconnect queue. Eleven times smaller than Australia, far more rapid and ambitious decarbonization based on the economics alone. I would not expect the remaining coal (14GW) and gas (66GW) in Texas to be around long.

(we deployed about 1GW/day of solar on average globally in 2023, and this is expected to rise to ~2.7GW in 2024, reaching 1TW deployed annually; the US is also now one of the largest LNG exporters in the world)

Natural gas isn't so terrible for the environment, despite not being renewable.

But coal? Yikes. As you've said it, as gas is so cheap, perhaps use lots of gas and invest in renewables. But go coal-free.
