Quite clever reclaiming the energy from the data centre as heat I guess but energy is still being consumed to run it. Don’t know much about them but if they’re springing up everywhere with high energy requirements they’re perhaps just increasing the burden on energy supplies whatever the source of the power
May not make much sense but a bit like recycling, if we didn’t have recyclable packaging to dispose of there’d be no need to recycle it.
Yes, data centres chew energy, but the point is that it’s better to find ways to use the heat they generate than it is to waste it as is the case in most large data centres. I’d guess that it would be more efficient to make large data centres recover and use the heat they generate. There are a few that do this, to heat local housing or a public swimming pool for example, but most will be using active cooling that is putting that heat straight into the atmosphere 24/7.
New data centres could be made to work off grid and without using fossil fuels but of course if any country passed legislation the centres would simply move to a country where they don’t give a ****.
Yes, with a bit of thought and planning, you’d think there could be a more joined up approach to data centre location and potential users of waste heat.
Not far from us is the old National Gas Turbine Establishment site, which has now become a big new housing development. Across the road from this development are a couple of large data centres, venting all the waste heat to air. I’m sure there could have been some better thinking here, perhaps in a district heating system for the new development using the waste heat for something useful.
Data centre in the shed reduces energy bills to £40
energy bills drop dramatically, from £375 a month down to as low as £40,
The heat hub is not solely relying on heat from the shed to heat the house, there doesn’t seem to be any indication of the savings due to the data centre.
There is also a link provided, which you would have thought the BBC would have read, that indicates the manufacturer claims the heat hub can provide savings of between 20% and 40%. This contradicts the headline savings.
I doubt the energy centres will be venting much heat. They will be actively cooled, the air inside the the data centres will be about 20c. The chillers will be producing heat, but they will be outside, so it’s not easy to capture that heat and re-use it.
But, it’s something they will be working on. It makes sense.
It can be done on a small scale. All new Sainsbury’s stores are heated using waste heat from the chillers, used to cool the cool aisles. They are also upgrading existing stores, but obviously that will take time.
To be fair they did say in the article that solar panels and a battery installed at the same time contributed to the savings, but yes, the headline taken on its own is misleading.
I am absolutely not suggesting anyone rushes in and buy’s Scottish Mortgage stock, even if SpaceX is its biggest holding and is still trading at a 12% discount.
