There's a huge amount of uncertainty, mainly. The EPA is trying to act on its own, and despite losing lawsuits, cost of regulatory compliance and lawsuits goes up. Investors don't want to risk entering the "new market" in case the "old market" isn't actually shut down or run out of town and remains competitive. Uncertain indirect subsidies via govt driving up your competitors costs is less enticing than guaranteed subsidies for building more wind and solar. The best solution is not allowing arbitraty administrative agencies to take the place of legislative certainty. But that's been deemed unacceptable by those demanding change at all costs despite lacking popular or legislative support.
