That's sad. Texas is pretty green in terms of power generation - even compared to California. Texas is 20% renewables [1], California is 32% [2].

Texas, by contrast, has close to zero 'large hydro'. It's not clear to me that 'large hydro' is a non-renewable', certainly it's a lot different from most non-renewables, and it's not carbon dioxide producing. If you take that into account, then from (coal/natural gas/oil/nuclear) California has more like 53% of energy while Texas has 80%. That gives a little different perspective.
Compare, e.g., with this list, which includes hydro as a category of renewables: https://en.wikipedia.org/wiki/List_of_U.S._states_by_electri...
