Energy Storage 9+3 (15)
Inspiration 8
Glyph of Elemental Power
Thunderclap {elite}
Lightning Orb
Lightning Strike
Energy Tap / Aracne Mimicry
Spirit of Failure
Conjure Lightning
Ether Feast
With the Glyph, Thunderclap will only cost 5 energy each time it hits, making it optimal conditions for energy management. Use Orb and Stirke sparingly, as you do not want Conjure Lightning to go to waste. Spirit of Failure is a good way to combat the energy loss from Thunderclap.. cast it on a warrior or ranger and you should get a good amount of energy. Then, when energy gets lower, use Energy Tap on a higher energy source (not ranger or warrior). The other option to Energy Tap, which i hate the 3 second casting time, is Arcane Mimicry (only if you know what spell your getting). Sometimes in TA you can find another elem that will have Ether Prodigy, Renewal, or a mesmer that will have Energy Drain. Obviously, this is very rare that you can make this work, but when you do, it drastically helps.
I made this build because i was tired of all of my elementalist builds being prone to either quick energy depletion, or being pwned by Enchantment Removers. This build only has one enchantment, and if it gets removed, you still get all of your kds with Thunderclap, and you still have Strike and Orb to dmg. With all of the mesmer energy replenishing spells, i find that despite Thudnerclap, energy management is not much of a problem.
I realize that Thunderclap is usually used E/R or R/E and a shocking bow string is used, but this build has more damage output if played correctly, please keep that in mind

Looking forward to comments/questions/critques
