Now, electrics are my favorite type. But, i don't know if they are in any biome or certain ones?
So, if someone could please write back that would be nice.

I mostly see Electric types in the plains. Here's a small list of my observations:

Voltorb/Electrode- Plains
Mareep/Flaafy- Plains
Magnemite- Tundra
Pikachu/Raichu- Plains or Forest
