There's 3 options for gaining XP quickly. In order of least energy efficiency to greatest - the furthest quest you have access to, Karma Dungeon Lv 3 (368/en), Trials (but you can only get the xp once)

Trial 001 awards 20,000 xp for 50 energy. That's 400/en Trial 002 awards 30,000 xp for 50 energy. That's 600/en and so on...
