Senate Panel Approves Energy Bill
June 18, 2009 06:26 AM - JOHN M. BRODER, New York Times

A Senate committee on Wednesday approved an energy bill that would open large tracts of the Gulf of Mexico to oil and gas drilling and provide federal loan guarantees for a gas pipeline project in Alaska. The measure, which cleared the Senate Energy and Natural Resources Committee on a 15-to-8 vote, would also require utilities to produce up to 15 percent of electricity from renewable sources like wind and solar power by 2021. That standard is somewhat weaker than one in a House energy and climate change bill that is headed for a floor vote as early as next week.
