"Bloomberg News reports[1] that David Keith, a Harvard professor of applied physics and public policy, used to be a solar power skeptic but has reexamined the economics of current solar power and now expects solar power to be important because the economics have changed." I don't follow solar/power/coal news much, so forgive me ... Is all of this ex-subsidies ? That is, if we remove the subsidies that coal gets and the tax credits / subsidies that solar gets, does the math still pencil out in the way that still makes David Keith no longer a skeptic ?

Yes, solar and wind are both below the cost of coal, natural gas, and nuclear, without subsidies (doesn't take capacity factor into account though). I'm always reposting that data here, so I won't dump a full page of citations here, but if you response with contact info, I'd be happy to send detailed information.

> Is all of this ex-subsidies? Also ask what price point would be needed to scale back CO2 emissions to something sustainable. Then run the economic analyses.
