Discussion on:

From deep underground, data center will help heat Helsinki homes

I really applaud the heat capture but at the same time they are saving
energy use on the inside of buildings, the solar exposed exterior is
being "radiated" and producing energy that is heating the atmosphere.

Very progressive on their part I will provide a link where they can see
time-lapsed infrared videos of buildings becoming urban heat islands.
See what a coat of paint or shade does for a building.

You still don't explain the significance of the church. Although, I
have a hunch you are implying something: Was there some sort of
gentlemen's agreement to not bomb churches in WWII?

The church mentioned is a Russian Orthodox Church. Perhaps Russians did not want to bomb it during the war years. Secondly it was situated on the outskirts of the city near harbor, and I think it is a island originally, or Peninsula. As I remember it over 60 years ago when visiting the church out of curiacity, it also was sitting pretty alone by itself there. Nothing much else were there at that time. This majestic church on top of the hill that one can see from everywhere in the city.
How do I know this? I am a Finn born in Helsinki, living in California now. Good for Finns for their clever use of extra "green" heating .

This is a tired old claim and no longer credible. Only the incompetent are now building data centres that lose 50% of their energy in cooling, across most of Europe / North America you can build a data centre which only needs chillers for a couple of hundred hours per year without any innovation.
This 50% claim is like Chevrolet claiming their new car will save 50% on fuel because it is better than a Ford model-T.
On the flipside the sourcing of the energy from geothermal is very smart and should actually be the focus of the PR.

I thought the cave would produce natural cooling. Wouldn't there be a
net savings because of that? If it saves it is a good idea.

"the server farms run by Google alone use 1 percent of the world?s energy"

That is a pretty amazing claim. Where did you get this information. I have a hard time believing this is true.

More like 0.5% of the power used in the UK!!

"the server farms run by Google alone use 1 percent of the world?s energy"

Source? That's a stunning figure. I'd find it hard to believe if you said "server farms use 1 percent of the world?s energy"...

Who called me ? The information about unknown phone number to find out who owns that number and why they call. Who is calling me.
