> When you drop a data center into an area, energy prices will spike

Why is that?

Where I live my energy bill is a fixed cost. It's a super expensive fixed cost, since I'm living in Germany, but it is fixed none the less. It increases year by year because all costs only go up, but it remains completely unaffected by unrelated infrastructure being built around where I live.

I've been to a data center before due to work and my impression of the place was really good. It's kinda invisible from the outside, everything is extremely clean. There's no noise on the outside and the excess heat is used to get people cheap warm water or something like that.

I'm quite confused why people suddenly hate on them. Feels like I'm missing a whole lot of context.
