Energy is the only studio album by the American ska punk band Operation Ivy. It was originally released on vinyl and cassette in May 1989 through Lookout! Records with the catalog number LK 010. Although the album itself has never been released on CD, all of the tracks were featured on the career-spanning compilation Operation Ivy issued by Lookout in 1991. Despite achieving no mainstream success, Energy is considered one of the most important albums of ska punk and is frequently cited as an influence by many later bands of the genre. The album stayed in print on Lookout until 2006, when the band took back its recordings from the label due to unpaid royalties. Guitarist Tim "Lint" Armstrong's label Hellcat Records re-released the original album as a 12-inch LP picture disc in 2004, and in 2007 put out a remastered version of the self-titled compilation. A second vinyl edition was released by Hellcat on April 18, 2012 and debuted at number 13 on the Vinyl Albums chart.

Figuring the band was not ready to record an album, and fearing that Lookout did not have enough money to put it out, Livermore and Hayes attempted to talk the band out of their decision, but to no avail. As guitarist Lint would later say, "You can tell Operation Ivy, but you can't tell 'em much." The original intent was to record the album live at 924 Gilman Street during closed hours with minimal overdubs, with Gilman soundman Radley Hirsch as engineer. "I think they were hoping to capture the electricity and excitement of their live shows, a nice trick if you could manage it", Livermore later said. "But without an audience, Gilman was just a barn-like structure with mediocre acoustics. It lacked soundproofing, isolation booths, a control room and all those features." During recording, however, the band ran into a number of disagreements with Hirsch, such as not wanting
