EV economics updated and a Catch-22

EV economics updated and a Catch-22: "calculated the annual pounds of CO2 the Camry would produce. Using EPA mileage, 12,000 miles per year, and the EPA’s CO2/gallon of gasoline figure, I computed the Camry would produce 9,502 lb/CO2 per year.

Next, to calculate the Leaf’s CO2 production, I adjusted the Leaf’s kWh consumption back to the generation level by adding back transmission system losses. Then I determined the amount of natural gas consumed using night time combined cycle heat rates of 7,500 Btu/kWh.
