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.
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.
Emperor Palpatine, also known as Darth Sidious, is not only the first Star Wars character to use Force lightning onscreen, but also the ability's deadliest practitioner.
At one time, it was classified as a forbidden Force power within the Jedi Order; however, some Jedi such as Plo Koon, Luke Skywalker and Jacen Solo practiced it.

Is there a Jedi version of Force Lightning?
Electric Judgement
Also known as Emerald Lightning, this Light Side variant of Force Lightning was used by some Jedi Knights and Masters to launch green or orange bolts to stun or kill their enemies.
Darth Vader can not use force lighting, because of his severed arms. Robotic hands can't summon the force lighting. However Darth Vader can still use other forms of the force, such as force choke.
Some have even speculated Sith can grow addicted to Force lightning. This naturally explains why Jedi do not generate Force lightning. Jedi seek to master their emotions rather than be mastered by them; Force lightning is therefore forbidden, as it is best understood as a spontaneous outpouring of hatred and rage.
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.
During the mission to Pasaana, while battling Kylo Ren, the Jedi Rey released a burst of Force lightning so powerful it was able to obliterate a First Order troop transport ship.
However, there is a third variety seen only by the most dangerous masters of the Dark Side: Red Force Lightning. Unlike normal Force Lightning, Red Lightning was generated by a Dark Side individual gathering and releasing cosmic energy of the universe itself. It can also be used to suck the life out of a target.
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.
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.
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.
And therein lies the answer. Sith specifically channel Force lightning using their hands. Seemingly, because Vader's hands are no longer there, he can't channel the dark side of the Force through them, meaning that he can't use Force lightning.
This could change over time as Cal succumbs further to the dark side's allure, so his Force Lightning could start off stunning his opponents before inflicting damage, then ultimately being used to kill.
Like his master, Darth Sidious, better known as Sheev Palpatine, Maul's main weakness was his overconfidence. In Luke Skywalker's confrontation with Palpatine during The Return of the Jedi, he tells the Emperor that his overconfidence is his weakness.
Due to Vader's mechanical suit, he cannot interact with lightning under the pain of suffering malfunctions in the vital life support systems he uses. This is a rare problem for him to come up against, due to only other Sith commonly utilizing such a capability.
Darth Vader's true form, revealed in a Star Wars comic, is even scarier than fans can imagine, showing his remaining humanity being overwhelmed by darkness. In his meditation, Vader is depicted floating among a lightning storm over dark waters, covered in bloody tendrils and represented by white missing limbs.
You can bounce enemy blaster bolts back at them to wound or kill them, or use them as a one-hit shield to stop blaster fire. Once you kill 50 enemies, you will temporarily gain Force lightning, which you must hold the Force button to use.
