What I think would happen in a realistic wold with Pokemon (lol) is that while the predictable stuff like Electric types being used for power generation and grass types being used for their produce would happen, I believe that highly intelligent Pokemon Like Alakazam an the Lati Twins would be the reason for advance civilization the cities that benefit from that kind of stuff. Why? No humans. That's right, I believe that in a realistic Pokemon world Humans would die out way before they start civilization. Pokemon can use moves like Double Team or Dig to defend themselves and humans have pointy rocks on sticks at best before carnivorous Pokemon use us as a defenseless meat source. Even the non-carnivores would be lethal to us with their self defense. I don't need to use individual Pokemon as examples, because I can use entire types instead. Fire burns us, Ice freezes us, Poison poisons us, Electric electrocutes us, and Ghost eats our souls. In the unlikely case that humans do survive long enough to see civilization, I believe that it would be as livestock. From a Pokemon's point of view, humans are so stupid that we can't understand them, so they shouldn't have any reason to feel bad about anything stupid as human, right? Long story short, were ether dead or Man Chops.
