For people who support this kind of ban, I'd ask if you would support a similar ban on new factories for, say, car parts. Like data centers, factories use a lot of power -- which drives up electricity bills -- and their construction can have local environmental impacts. Data centers have a reputation for not providing too many local jobs, but modern factories are often highly automated and also don't provide too many…
Why not just require factories /data centers invest in solar/wind/renewables to cover their power usage. Banning is so childish when there is easy solutions.
What we _should_ be asking is where all the money we paid for infrastructure and upkeep went for the last two decades of decreasing power usage.
