NOx regulations that make more smog but mandate construction of new plants that replace the old instead of increasing capacity. That creates power shortages that drive prices up.
Mandate oxygenates that polluted groundwater, produce asthma cases, and then the agencies use the cases to mandate more regulations. Resulting boutique gasolines require massive amounts of natural gas. Guess who wanted those regulations?
It's corruption. There's so much of it that I could write a book, but then, I already did.
