The study's major mistake was to highly penalize solar for availability. Why? As long as there are other fuel using waste producing assets that can be idled when solar is available, every kilowatt can be productively used.
You want to build an expensive fossil fuel plant and run it only part of the time, and you don't think that solar should be penalized for the inefficient use of the fossil fuel plant?
You're yet another example of a liberal who failed economics.
We already have all of the fossil fuel pants we'll ever need.
You're yet another example of a conservative who failed common sense.
Solar, but more particularly wind NEED to be penalized for inefficiencies associated with idling the main generators. You cannot idle a coal plant and expect it to be there instantly when a cloud passes by or tthe wind lulls. Nat gas and hydro are quicker, but when you shut down a nat gas gas plant, you are wasting heated water .. Same with a nuclear plant..
These are REAL costs of trying back up unreliable sources...
