In an article posted the other day at U.S. News & World Report, Marianne Lavelle reports on the state of affairs in the renewable energy industry. While the story she tells is a good one, she makes two stunning errors that lead me to question every other figure reported in the article.
Error #1 -
Historically, ethanol has been more expensive than gasoline, but crude oil prices are now so high that ethanol would be cheaper even without its 51-cent-per-gallon subsidy. Indeed, one reason pump prices have not skyrocketed along with the price of crude oil is that so much fuel is blended with 10 percent ethanol.
Really? Ethanol (E100) prices on U.S. spot markets last week averaged $1.87 a gallon. That is indeed cheaper than the price of conventional gasoline in those same markets ($2.25 per gallon), but ethanol has only two-thirds of the energy content of gasoline. If you want to buy enough ethanol to displace the energy you get from a gallon of gasoline, you would have to spend $2.80 per gallon. Hence, ethanol is not cheaper than gasoline, and federal mandates to use ethanol in transportation fuel does not reduce pump prices.
Error #2 -
The plug-in advocacy group CalCars estimates that with today’s electricity prices, drivers would be paying the equivalent of 75 cents per gallon [were they to run their cars on electricity rather than gasoline].
Again, really? Electricity prices last week averaged 9.57 cents per kilowatt hour. Given that there are 3,400 BTUs in a kilowatt hour of electricity and about 124,000 BTUs in a gallon of gasoline, simple math dictates that it would cost almost $3.50 to buy enough electricity to get the same amount of energy we get from a gallon of gasoline.
Reporters have got to stop taking figures at face value from policy activists with political axes to grind. And editors have got to start asking reporters to independently back their numbers up. Until that happens, don’t bother with the print media. The “facts” bandied about therein are a crap shoot. Some are correct, some are not, but you never know which.
