The skyrocketing cost of rare-earth metals from China is pushing up the
cost of gasoline production in the U.S., the latest sign of the wide-

Prices for some of the chemicals refiners use to process gasoline have

The average gasoline price is calculated by the Energy Information Agency,

A gallon of ethanol gives about 77 KBTU, and require 35KBTU, and thus net

A gallon of gasoline gives about 125 KBTU and requires about 15 KBTU, and
thus net energy is 110 KBTU, more than 2.5 times higher than ethanol.
Ethanol is about $2.02 /gal (after 0.51/gal of tax-payer money subsidy) in
