Computers and global warming
« on: 12 November 2019, 20:58:10 »

Could it be that cars and cows are not the whole problem.?

Everyone has a computer generating heat and powered by electricity.

Everyone is taking millions of photos all stored in something called the icloud, one drive or similar. Those servers must really be kicking out some heat.

Just a thought

There's a server bank in Orkney that's actually in a container on the seabed for that very reason. The servers are kept cool and the seals kept warm 8) Not sure what the polar bears make of the whole thing though...  :D

A lot less than 20 years ago, per server.. although there are a lot more servers out there now, I'd wager. That said, data centres have been switching to sustainable cooling & power for some time - it's why there are a number in Iceland (geothermal power), Alaska (free cooling) etc.

Fun fact, when Facebook brought up one of their passively cooled data centres, it created its own microclimate and rained inside the building - complete with rain cloud. https://www.theregister.co.uk/2013/06/08/facebook_cloud_versus_cloud/

As DG says, various companies are experimenting with dumping container loads of computers (ok, it's slightly more complex than that - https://news.microsoft.com/features/under-the-sea-microsoft-tests-a-datacenter-thats-quick-to-deploy-could-provide-internet-connectivity-for-years/ ) into the sea. Given the thermal mass of the sea, their heat output is a literal drop in the ocean..

I bet there are more computers than cars .  Even powered by green energy they are still contributing to global warming.

We need to get Greta on the case. Free abacuses for those scrapping their computer..

There must be, each car has multiple computers in it  ;D ;D

 I think having computers pumping out heat reduces global warming, as at this time of year we can turn the central heating down, maybe they should give these hard up pensioners a couple of servers in each room, and then the government could save millions,by withdrawal of the cold weather payments.   Win win.

Between the laptop, Tibetan Terrorist and a 13.5 Tog down duvet, I hardly ever have my radiator on...  :D

Its a lot less than you may think, and as has been said, there has been a big push in more energy efficient (more due to energy costs than tree hugging) equipment and cooling.  Generally the same amount of energy is needed for cooling as is used for the equipment.

The DC where I'm based* - think 4 small sports halls rammed with 1U and 2U servers, along with 20U and 40U routers and bloody great storage arrays - probably uses less power now than when it had a handful of mainframes 25yrs ago.


Based as in my official office. I support no kit there (their support teams are up north), all my stuff is scattered around the country.

No, I just have blood in my veins, and good circulation ;)

The servers we currently use - HPE ProLiant gen9 - for the load they are under, pull little more than an old lightbulb, each.

Ensure you have plenty of built in insulation like me.

Oh, hang on a min....
