Are you getting the NG delivered by pipe?

I am assuming a BTU of fuel will make so many Wh of energy.

That would cost me *$35* from the power utility.
A gallon of diesel is abou $3.25 around here. 139000 btu.
Diesel then is about $23 per 1M btu.
However diesel engines are only 30% efficient so it will cost me *$76*
in fuel to make that 292.3 kWh
If that assumption is approximately correct:
I pay about $7.80 per decatherm in the winter for NG. A decatherm is 1
million btu
About half that in summer.
$7.80/.3= *$26*/293.3 kWh for NG not considering depreciation and maint
of the generator.
It seems to me that NG is the hands down fuel cost winner? Anyone see
mistakes in this?
