President Bush is threatening to veto an energy bill that would raise auto fuel efficiency standards for the first time in thirty-two years. On Thursday, the House approved the energy bill by a 235-to-181 vote. The bill would raise the corporate average fuel economy level for cars and light trucks to thirty-five miles per gallon by 2020. The legislation also revokes $21 billion in tax breaks to oil companies and will require utilities to produce 15 percent of their power from renewable sources by 2020. The bill now goes to the Senate. Republicans criticized the bill because it would increases taxes on oil companies and not boost production of oil, natural gas or coal.
