Men den brave miljøforkæmpers forbrug af naturgas blev kun nævnt i forbifarten.
“What’s maybe even more interesting is the gas bill, reported to average $1,080 a month over the last year (none of these figures, first released by a Tennessee free-market think tank, have been disputed).
Nobody else seems to have done so, so it’s interesting to see what that translates into in terms of emissions.
We learn from the US Department of Energy that Tennessee residential gas prices were around $13.50 per thousand cubic feet last year. So $1,080 would buy about 80,000 cubic feet. That dollar amount is an average monthly figure, so that would account for 960,000 cubic feet over the course of the year.
One cubic metre equals 35.29 cubic feet, so that translates to 27,200 cubic metres.
One cubic metre of natural gas emits 1.891 kg of CO2 (see page 13), so this represents a total of 27,200*1.891 = 51435.2 kg (51.4 tonnes) of CO2 emission.
By striking coincidence, this is within a whisker of total CO2 emissions per average US household – including household operations, automotive uses, and “indirect emissions” – which amount to about 118,000 pounds (53,636 kg).
The point bears repeating. Mr. Gore’s natural gas-based emissions alone account for as much warming as the total due to electricity, heating, transport and “indirect” factors of an average American household.
But that’s OK, isn’t it? After all, the Gore family purchases carbon offsets – “a concept the right-wing fails to understand“.”
