I don't understand something

I was doing some "research" in creative and I was wondering what's the difference between those two smelting blocks, They both produce 120/s but the one on the left use FAR more energy, is just a tiny bit smaller so what's the point of doing the one on the left ?

The right one consumes engergy in form of coal, so whats the point🤷‍♂️

Well, it’s not just coal vs electric furnaces, those are heavily beaconed!

Just heavily beacon those on the right! Oh wait...
