One of the useful exhibits incororated in Managing the Transition to Climate Stabilization is the tabulation at left. This is a convenient comparison of projected cost premiums for carbon-friendly electrical generation options. I believe the backup for these costs per kilowatt hour is in the CCSP papers — I just haven’t had time to dig through those yet.
There is a similar tabulation for nonelectric fuel options.
Keep your eye on that expensive PV row. It’s the only one with something like Moore’s Law deflation going for it. Tech advances could shave a bit off some of the other options, but already new efficiencies and designs are emerging from the labs. For that matter, an older technology called Ovonics hasn’t been nearly fully exploited yet.
