Yes, the economic factors are the result of EPA regulations that the Obama administration put into effect.
Which economic factors are those? You mention them without specificity.
Like, are you talking about the reason it retired Unit 1? That was because Los Angeles Department of Power and Water sold its 21% share to a public utility, the Salt River Project.
Maybe we should take it from Peabody Energy, who provided the NGS with coal and filed for bankruptcy last year: "The company cited an “unprecedented industry downturn,” which it attributed to a range of factors including an economic slowdown in China, low coal prices and “overproduction of domestic shale gas.” In the United States, cheap natural gas, driven by the shale-gas boom, has been steadily eating into coal’s share of electricity generation."
So, how has the Obama Administration responsible for: (1) the economic slowdown in China; (2) low coal prices; and (3) the overproduction of domestic shale gas? And, presuming these facts to be true, how can these not be linked to Republican policies regarding: (1) enforcing competition laws against China; (2) de-regulating coal to lower its cost; and (3) permitting and proliferating shale gas mining operations in order to combat OPEC-directed oil shortages?
Please respond with something more than "because." I'm interesting to know how Pruitt plans to change all of this, and meet Trump's mandate of "saving coal."
