On Capitol Hill, the Senate has voted to force automakers to raise fuel efficiency standards for the first time in more than 20 years. The bill calls for all new cars, trucks and SUVs to get an average of 35 miles per gallon by the year 2020. Meanwhile, Republican senators stripped sections of the bill that would have required oil and gas companies to spend some of their profits to help research renewable energy sources. Republicans also blocked a proposal to require utility companies to produce 15 percent of their electricity with renewable fuels by 2020.
