Republican opponents said the legislation ignored the need to produce more domestic oil, natural gas and coal. One Republican lawmaker bemoaned "the pure venom ... against the oil and gas industry."
The House passed the tax provisions by a vote of 221-189 Saturday. Earlier it had approved, 241-172, a companion energy package aimed at boosting energy efficiency and expanding use of biofuels, wind power and other renewable energy sources.
"We are turning to the future," said House Speaker Nancy Pelosi.
The two bills, passed at an unusual Saturday session as lawmakers prepared to leave town for their monthlong summer recess, will be merged with legislation passed by the Senate in June.
On one of the most contentious and heavily lobbied issues, the House voted to require investor-owned electric utilities nationwide to generate at least 15 percent of their electricity from renewable energy sources such as wind or biofuels.
The utilities and business interests had argued aggressively against the federal renewables mandate, saying it would raise electricity prices in regions of the country that do not have abundant wind energy. But environmentalists said the requirement will spur investments in renewable fuels and help address global warming as utilities use less coal.
"This will save consumers money," said Democratic congressman Tom Udall, the provision's co-sponsor, maintaining utilities will have to use less high-priced natural gas. He noted that nearly half the states already have a renewable energy mandate for utilities, and if utilities cannot find enough renewables they can meet part of the requirement through power conservation measures.
The bill also calls for more stringent energy efficiency standards for appliances and lighting and incentives for building more energy-efficient "green" buildings. It would authorize special bonds for cities and counties to reduce energy demand.
Pelosi, a Democrat, said it was essential to commit to renewable energy while reducing reliance on fossil fuels. Doing so, she said, will help address global warming and make the country more energy-independent.
"It's about our children, about our future, the world in which they live," Pelosi said.
