To me, there is a lot of blame to pass around. I don't think you can simplify the world by selecting one causative agent. It seems to me that all the selections above were just a part of a much bigger picture.
It's my opinion that the "big picture" is the loud and often exaggerated noise of the far left politicians and their minions when ballyhooing the benefits of the NEW GREEN DEAL.
Now, all at once .........."Miller is against renewable energy and doesn't care about the planet!!"
Of course, that's wrong. Am I against wind and solar power? Absolutely not. However, I think the noise from selling the product has exceeded it's ability to perform. I believe solar and wind generated power has been oversold. I believe renewable energy is not quite ready for prime time. I am for continued research and development of renewable energy and it's use, but NOT TO RELY ON IT. It is not perfect. I feel some flaws have been exposed, as evidenced by the Texas incident.
I believe all the potential culprits mentioned above made the same mistake. They over-relied upon loud and boisterous noise of overzealous supporters when selling renewable energy. Power plants were taken off line. Gas pipelines were cancelled. Anti-freeze methods were relaxed because of typical Texas weather. Suppliers let maintenance efforts slip. Committees made bad contingency plans when relying on renewable energy, and on and on.
All mistakes were made because of a single issue. Solar and wind energy was oversold. And, the government is spending more money on subsidizing this research than keeping proven supply channels open and sufficient to meet emergencies. Any business school undergraduate should know this. It is just damned poor planning caused by too much hype from the left.
I know this. I would hate to have 29 million Texans pissed off at me.
