I know there’s no single answer, but it seems to be surprisingly hard to get even a ballpark figure to this question: approximately when did electric power become a “standard feature” in reasonably sized towns/cities in the “developed world”? (I’m thinking mostly of the US and the UK).
I find a page (from the UK) saying that mains electricity was introduced in 1882, although it doesn’t say where. Wikipedia expands on this by saying that the town of Godalming (only a few miles from where I live!) was the first to have electric street lighting in 1881, with mains power following in London and in NY in 1882.
But presumably these were fairly pioneering supplies. What I really want to know is at what stage houses began to be built with electrical wiring and sockets as standard. Assuming the town in question had an electricity supply, would new houses being built in, say, 1910, likely have mains electricity as standard, or would people still have to get it installed especially?
I know the dates will vary a lot by area, but if anyone can dig up any links showing when various cities got powered up, that would be great.
