President Barack Obama will double down on his “all-of-the-above” energy strategy on Thursday when he announces the Interior Department’s new lease sale to make roughly 38 million acres available for drilling in the Gulf of Mexico. The announcement comes as part of the president’s post-State of the Union trip through Las Vegas and Denver, where he’ll expand on the energy blueprint he laid out in his address on Tuesday night. In his State of the Union speech, he vowed “responsible development” of domestic oil and natural gas. Speaking at a UPS refueling facility in Las Vegas, the president will detail the terms of the June 20 lease from Interior’s Bureau of Ocean Energy Management, which could yield up to 1 billion barrels of oil and 4 trillion cubic feet of natural gas off the coasts of Louisiana, Mississippi and Alabama.
