Since you're using Emolga on Wifi, I'll put my full critique into it since I don't have to consider in-game aspects.
Emolga has a terrible time trying to compete with the other Electric/Flying types, both of which are legendary. Emolga, when compared to them, just can't compete.
Even as a Pokemon in general, it's just a terrible choice. I've seen many Pokemon with low stats still be used on Wifi because of their niche (Mawile and Weezing, for example). Emolga has low stats but that's not what makes it bad: it's stats re so horribly placed that it can't do anything!
This thing has nothing to set up with that Speed, its typing is pretty good, but most Pokemon online who learn Earthquake also learn Stone Edge. It has 75 attacking stats, 55/60/60 bulk, which is a joke, and Speed that still lets it get outrun by many threats.
Its movepool is pretty fair, intertwining two useful movepool aspects that come from Electric AND Flying-types. The problem is that, with its stats, it can't put any of it to use. Even with that Speed, it could be used to set up stuff in NU. Too bad it can only set up Light Screen, though.
So yeah, in short: Emolga is far from worth using. In fact, I'd recommend to never use it. Ever.
