Half Hour of Power is Sum 41's first album. It was released on June 27, 2000 on Big Rig Records, a subsidiary of Island Records (US), and Aquarius Records (Canada).
The album is dedicated "in loving memory" to the band Closet Monster. The album title is a direct reference to its running time which is about 30 minutes (a few minutes of silence were added to the final track to make up this time).
This is the first of two times that "Summer" appeared on a Sum 41 album, the second being All Killer No Filler. The band planned to put the song on each of their albums as a joke, but scrapped the plan after All Killer No Filler.
Three of the songs on the record, "What I Believe", "Another Time Around" and "Summer" were all originally featured in their first-stage demo versions on the "Rock Out With Your Cock Out" demo tape.
