"Critics have derided Perry's proposal for its potential to upset the last two decades of electricity generation, which have been marked by free competition and little intrusion by the government."

Breathtaking intellectual dishonesty!  Intrusion in power markets by federal and state govts over the last 20 years, o renewables' behalf has been unprecedented.  Not only the heavy subsidies that renewables get (e.g., production tax credits), but more importantly the literal (state) mandates for large amounts of renewables use.  (CA's is 50%, and they may try mandating 100%).  Such mandates go way beyond affecting competition, they eliminate competition entirely.  And yet, such large interventions get no complaint from these "experts", whereas there is a huge hue and cry over much smaller support for coal and nuclear.

YES, the tax credits are a thumb on the scale!  Why doesn't Perry come out and say it?  BTW, the PTC phase out dates are meaningless.  Congress will just extend them, again.
