"Dieselpunk" is sometimes considered the next door neighbor term for WW1 through early 1950's retrofuturism with electricity and radios/very early televisions.
Sometimes people use "Steampunk" for shorthand for both because there are some overlaps in either direction, especially if you are trying for "just" pre-WWI retrofuture. Though I think the above poster was maybe especially trying to highlight the sort of pre-WWI overlap with Steampunk with more electricity but not yet as many cars and "diesel".
