To everyone arguing about the costs, pic related happened. The original $45bn estimate was done in 2006, then in 2008 QE and money printing happened causing the dollar's value to defacto drop by 50% by 2012 resulting in the new $80bn estimate. This is also why everything else is expensive too, like gas being $3.50 now and not $1.50.
And more to the point, from the get go the Feds were going to supply about $33bn plus $10bn in a Prop 1A approved bond sale, which gives us a $32bn gap. However thanks to cap-and-trade's ~$1bn per year through 2030, this brings the final shortfall down to $22bn (and $0 if cap and trade continues indefinitely or has more than $3.2bn in yearly revenues through 2030).
