Washington ? Citing the public outcry about $3-per-gallon gasoline and America’s heavy reliance on foreign oil, the House on Thursday voted to open an Alaska wildlife refuge to oil drilling, knowing the prospects for Senate approval were slim.

Drilling proponents argued that the refuge on Alaska’s North Slope would provide 1 million barrels a day of additional domestic oil at peak production and reduce the need for imports.

But opponents to developing what environmentalists argue is a pristine area said Congress should pursue conservation and alternative energy sources that would save more oil than would be tapped from the refuge.

The House voted 225-201 to direct the Interior Department to open oil leases on the coastal strip of the Arctic National Wildlife Refuge – an area of 1.5 million acres that is thought likely to hold about 11 billion barrels of recoverable oil.

But the action may be little more than symbolic. Arctic refuge development, while approved by the House five times, repeatedly has been blocked in the Senate.
