I would promote a more conservative number, actually.

Where are you getting 6%?  :-)

$0.123 kWh is about what some New Englanders pay.  Similar costs are
found in other parts of the country, though that's twice what I pay.

Maintenance costs I'll agree with; amortization does not seem to apply
as you are already comparing to an interest-yielding account.

I would place the number closer to $0.25 kWh to be on the safe side.
Cheap?  Not in short term costs, but what does pollution cost us in the
long run?
