I wrote an article about the need for low-carbon and and the path towards zero-carbon computing.


** The problem:
* By 2040 emissions from computing alone will be close to half the emissions level acceptable to keep global warming below 2°C. This growth in computing emissions is unsustainable: it would make it virtually impossible to meet the emissions warming limit.
* The emissions from production of computing devices far exceed the emissions from operating them, so even if devices are more energy efficient producing more of them will make the emissions problem worse. Therefore we must extend the useful life of our computing devices.
** The solution:
As a society we need to start treating computational resources as finite and precious, to be utilised only when necessary, and as effectively as possible. We need frugal computing: achieving the same results for less energy.
** The vision: please read the article, I'm out of characters.


@wim_v12e I like your broad view on #greenIT!

I have been reading sustainability reports of some hosting providers and mostly they talk only about efficiency (= less idling servers, newer servers, and less cooling)... but #sustainability contains also consistency (which servers do I buy, which energy do I consume, which buildings do I have) and sufficiency ("less is more"/use only when necessary)

Though, the reports I liked the most:
- hostsharing.net/ziele/digitale (it's German only; they explicitly say that they run their hardware as long as possible and if they buy new hardware, then based on sustainability aspects, too)
- ungleich.ch (I believe their message, but they are small...)
see also
(maybe you have some other good examples)

But here again hosting providers are just the tip of the iceberg and relying on other resources like network, buildings, hardware vendors, cooling...

@greenfediverse FYI

@aligyie @wim_v12e @greenfediverse Buying new hardware as rarely as possible can be very bad for energy efficiency. Updating a rack of 2010 servers to 2020 ones can easily cut the power consumption in half while increasing the computing power at the same time.


@dmbaturin @aligyie @greenfediverse
In general for computing devices, servers as well as desktops or laptops, the total emissions from production exceed those from operation over a currently typical lifetime. So upgrading too soon to newer servers results in net higher emissions.
Of course the economic argument is different: it will reduce your power bill.
