It could take years for the US to refill its emergency oil reserves after last year's record sales

• It could take years to stock up the US emergency oil reserves after 2022's historic sales, per Reuters. 
• Last year, President Joe Biden ordered the release of 180 million barrels from crude reserves in a bid to lower gas prices. 
• The US energy secretary said maintenance costs at the Strategic Petroleum Reserve and last year's sales make it difficult to refill the stockpile. 

It could take years for the United States to replenish its emergency oil reserves after last year's record sales aimed at easing gas prices, according to energy secretary Jennifer Granholm.
