I wonder what the yin and yang / success rate of such mandates are / how the response really goes.
I remember the light bulb rules at a national level had to be rolled back when there just wasn't enough capacity to replace them all with non incandescent options.
The light bulb rules in the UK were frequently snorted at, but everyone has moved over now, and whether it is associated with it or not, we're using less electricity these days too.
