WASHINGTON (AP) _ President Bush, who has said he doesn't believe the government should set arbitrary automobile mileage standards, is signing into law a requirement that motor vehicles meet an average 35 miles per gallon by 2020.
Congress sent an energy bill to the White House late Tuesday _ delivering it in a gas-hybrid sedan _ that increases the federal auto mileage requirement for the first time in 32 years and also requires a huge increase in the use of ethanol as a substitute for gasoline.
The measure passed by veto-proof majorities in both houses. The House passed the bill 314-100, with 95 Republicans joining Democrats in support of the legislation, after the Senate approved it last week 86-8.
The White House immediately announced that Bush would sign the measure Wednesday morning at a ceremony at the Energy Department.
``This is a choice between yesterday and tomorrow'' on energy policy, declared House Speaker Nancy Pelosi, D-Calif., who had personally conducted the sometimes testy negotiations that led to the bill's approval in the House.
Democrats said the legislation represents a turn away from fossil fuels to using more renewable energy sources and put greater emphasis on conservation.
It increases energy efficiency ``from light bulbs to light trucks,'' said Rep. John Dingell, D-Mich., a longtime protector of the auto industry who was key to a compromise on vehicle efficiency increases.
The bill requires the industry to achieve an average of 35 miles per gallon for all vehicles, including SUVs and small trucks, by 2020, about a 10 mpg increase from what these vehicles get today. While all vehicles from small sedans to large SUVS must make some improvement in fuel economy, the required improvements may vary among vehicle classes as long as the overall industry average is 35 mpg.
The bill also calls for:
_ A sixfold increase in ethanol use to 36 billion gallons a year by 2022, a boon to farmers. Of that, 21 billion gallons will have to be from feedstock other than corn such as prairie grasses or wood chips.
_ Improved energy efficiency of appliances such as refrigerators, freezers and dishwashers, and a 70 percent increase in the efficiency of light bulbs.
_ Energy efficiency improvements in federal building and new efficiency standards for construction of new commercial buildings with an aim that they produce as much electricity as they use.
The new lighting standards alone are projected to lower consumers' annual electricity bills by $13 billion in 2020, remove the need for 60 mid-size power plants and reduce emissions of carbon dioxide, the leading greenhouse gas, by 100 million tons a year, said the advocacy group Alliance to Save Energy.
Democrats said the fuel economy requirements will save motorists $700 to $1,000 a year in fuel costs and reduce oil demand by 1.1 million barrels a day when the fuel-stingy vehicles are widely on the road.
The overall bill including more ethanol use and various efficiency requirements and incentives, will cut U.S. oil demand by 4 million barrels a day by 2030, more than twice the current daily imports from the volatile Persian Gulf, Democrats said.
But some Republicans complained the legislation fails to address the need for more domestic production of fossil fuels, especially oil and natural gas.
``What we have here is a mandatory conservation bill,'' said Rep. Joe Barton, R-Texas. He argued that the auto fuel efficiency requirements and the huge increase in ethanol use may not prove to be technologically or economically possible.
Earlier this year, Bush announced his own plan, which he said was aimed at cutting U.S. gasoline use by 20 percent in 10 years. Like the legislation passed by Congress, the president's plan included a sharp increase in ethanol use. It also urged Congress to overhaul fuel economy rules to give auto companies more flexibility, some of the provisions lawmakers adopted.
But Bush _ until now _ remained strongly opposed to any arbitrary, numerical increase in auto fuel efficiency.
The bill is HR 6.
