I actually think the people in this forum are pretty self-reflective and aware of a lot of the imperfections in the pro-car-free arguments made here. But I also think that people sometimes fail to see the big picture in their own fossil fuel use and that of others. I think that it's pretty normal to spend a substantial amount of one's income on electric and gas bills, which isn't really better than spending the same amount of money on gasoline in terms of how much fossil fuel energy one uses.
In the USA an average commute is 16 miles each way, and average fuel economy is 21 mpg.
If we assume that for car-owners commuting is a 5 day a week round trip and those (on average) 160 miles account for two thirds of their driving distance, then each motorist is driving 240 miles a week on an average of 11 gallons of gasoline/week= 48 gallons of gasoline/month.
I live with one other person in a small 1 bedroom apartment, and we put a lot of effort in to conserving energy. My 50% share of the apartment energy usage (electric/natural gas) is the equivalent of 18 gallons of gasoline* even though we run the heat low in the winter and do not use any air conditioning. (this is philadelphia, and as non-AC-owners we are quite unusual.)
If your rates are similar to mine, every ~$2.40 USD you spend on natural gas represents the energy of one gallon of gasoline, with dollars-of-electricity usually representing slightly less fossil fuel use.**
*70.5 kwh electricity plus 2,000 cubic feet (20 ccf) of natural gas = 238,000 btu electricity+ 2,040,000 btu natural gas= 2,278,000 btu = the energy equivalent of 18 gallons of gasoline.
(see here for conversion rates)
** assuming that your electricity is mostly fossil fuel with a little bit of nuclear/wind/etc, and accounting for the fact that many of the BTUs in fossil fuels that generate electricity actually go up the smokestack rather than generating electricity.
