Tony's was 7.18¢ per kWh. Mine is 9.4¢. And, for the record, my gas is $1.34 per therm and his is $8.67 per Mcf.

I found statistics that claimed about 4kWh of electricity or 0.22 therms of gas per load.

On a related subject, I can't believe that the gas company sells gas in units based on heat generation rather than on volume, even if it does more-or-less equal 100cf. But there you go.
