I've heard various arguments for this, none of which seemed that convincing. Centralized power generation seems like one of the great successes of the 20th century. What do you think the advantages of decentralization are?
From the point of view of large producers and investors, sure. Tesla's idea of decentralized power was viewed as pie-in-the-sky by his benefactor, JP Morgan.
I wouldn't call nuclear power a success story.
