WASHINGTON, D.C. - November 3, 2009 - Good news for American motorists: Despite doomsday prediction from energy-industry-funded interest groups, U.S. consumers actually will see a net reduction of $13 billion in 2020 and $46 billion in 2030 in their gasoline expenditures ($100 and $326 in average net savings per household, respectively) if Congress moves ahead to impose a cap-and-trade system, according to a new report from the American Council for an Energy-Efficient Economy (ACEEE).
