Instead, he viewed the Force more as a complement to his combat style rather than a direct tool to be utilized. All of this would fall in line with Maul being a warrior, more than a Force-user. Just because Maul never used Force lightning, that doesn't mean he couldn't.
Some members of the New Jedi Order such as Luke Skywalker (who also used the dark side version at times), Jacen Solo and Jaden Korr also used light side Force lightning known as "Emerald Lightning", or Electric Judgment, but it remained somewhat controversial to some Jedi.
Dooku first used Force lightning at a young age. According to the audiobook, Dooku: Jedi Lost, he was once abducted for a Dark Side ritual, conjuring lightning to kill his captors and escape. Dooku went on to become one of the greatest Jedi masters, but his ability to use lightning was seemingly a natural talent.
While many Star Wars fans would consider Yoda and Palpatine to be almost perfect antitheses of one another, it seems that they share a strange connection through Yoda's usage of Force Lightning in The Last Jedi that is eerily similar to something Palpatine did just a few years prior–and that connection goes much deeper ...
Why Darth Maul Never Used Force Lightning - Star Wars Explained
Who was the first person to use Force lightning?
Chronologically, Count Dooku is the first to use Force lightning in Star Wars: Attack of the Clones. He then goes on to use it extensively all throughout Star Wars: The Clone Wars, with he and Palpatine being the only people seen to use it in the prequels.
Kylo demonstrably couldn't defeat Snoke directly, instead killing his master via deception. Kylo most likely never learned how to conjure Force lightning, which is considered an advanced skill for dark side users.
Mace Windu, with his lightsaber combat form Vaapad, could reflect the lightning back to its source with a "superconducting loop". It required tremendous effort on the reflector's part, however, as seen in Windu's battle with Palpatine; Windu was seemingly able to overcome Palpatine's lightning.
She and Kylo Ren were both trying to bring the transport to themselves with the Force, and in her anger, she accidentally unleashed lightning upon it, destroying the ship immediately.
Either way, while Vader can use most other Force abilities, Force Lightning needs to be channeled, and Vader's limbs are explicitly not connected to the Force. The Star Wars: Episode III - Revenge of the Sith Visual Dictionary confirms Darth Vader cannot use Force Lightning, and even suggests this is the reason why.
It became seen as a gateway to the dark side, with some choosing to practice it in secret. Remarkably, Mace Windu is only one of a few Form VII users who didn't fall to the dark side thanks to his refining Juyo into Vaapad.
He just wasn't explicitly taught it, or dark side sorcerery more generally. His training was focused on the skills of a Sith assassin, being an overwhelming lightsaber duelist. You need real legs to be able to force-siphon the electric current from the ground. That's why Maul or Vader can't use lightning.
Two easily explainable reasons for why Maul never used Force lightning, which have come up several times, are one) that he wasn't a Sith Lord and two) he never learned the ability in the first place.
Yoda is a Jedi Master, and he's had centuries to perfect his skills. He's so attuned to the Force that he can channel it through his body, using it as a conductor to absorb and neutralize that electric zap. It's like catching lightning in a jar, but instead, Yoda just absorbs it into his green, wrinkly skin.
Anakin Skywalker's Chosen One Potential Was Permanently Stunted. The Darth Vader comic book series reveals that, while the eponymous Sith Lord was indeed capable of using Force Lightning, the electricity could potentially destroy his life-sustaining suit.
Using the Force, the Jedi and the Sith had the ability to deflect energy-based attacks like blaster bolts and Force lightning. A few even could block melee attacks, such as those performed with lightsabers.
Palpatine carried the lightsaber for a great deal of his life afterward, though he only rarely wielded it in combat, as his position as Emperor made battles with other Force-users few and far between, and he preferred to rely on his raw ability with the Force in any case.
It was a technique of telekinesis that was frequently employed by the Sith and other users of the dark side of the Force, although there were some cases where Jedi or other users of the light side would use the technique.
As a result, Palpatine's face changes in Star Wars: Episode III - Revenge of the Sith because his dark side-induced mask was broken by the Force Lightning rather than the Sith lord actually being disfigured by his own attack.
Ok so let's get into it Mace Windu survives, The fall but he has lost his weapon and is servilely wounded in now hostile territory. This is why I believe he would go into hiding for some time thoughout the early years of The Galactic Empire.
