HotBlast 1557m Blower fan help

[Jlawson23]

I got my grandfathers 1557m off of him as he said he is too old to be cutting wood anymore, I can’t remember a specific year when he got this stove but I do know he replaced the blowers on it once. My question is do they have a more “green” blower I can replace these with? I feel my electric bill has only dropped 20-30 dollars from running the ac in the summer.

Thanks so much!
