Iowa has more renewables than CA but has cheaper electricity prices than the national average. There are a few examples like this that prove that the inference you're attempting to make is symptomatic of stupidity.
Does Iowa have the same heavy handed government regulations to strictly build out renewables and take non renewable power plants offline?
I agree with you, Texas has the most renewables, and power is relatively cheap. The problem is the strict regulations prevent utilities from make better economical decisions.
