Green web hosting – We tend to think that going digital is better for our environment, surely there’s less printing and the recycling bins aren’t as full?
In fact the datacentres, where our website information is stored, are vast buildings packed with servers that require a lot of electricity to power them and just as much electricity to keep them cool. To generate much of that electricity, fossil fuels like coal and gas are usually being burned.
Whilst it may seem clean and efficient, the internet is actually a carbon producing monster.
We decided to move our own website hosting to Kualo, a green web host who use E.ON Rewables to power their UK datacentres. In the UK, their datacentre runs on 100% green-sourced power as specified by E.ON and regulated by Ofgem.
E.ON are one of the leading renewable generators in the UK with over 20 on-shore and off-shore wind farms, including the London Array, the world’s largest off-shore wind farm with a capacity of 630MW.
Kualo’s primary hosting facility, Centro, is not only powered entirely by renewable energy, but has also been built from the ground up to be extremely energy efficient. Part of The Green Grid industry body, Centro complies with the EU datacentre code of conduct and is audited and certified to ISO 14001 (Environment Management) standards. The facility achieves a class-leading PUE (Power usage effectiveness) of 1.2, making it one of the most efficient hosting facilities in service today.
In the typical datacentre, a huge amount of energy is used to keep the servers cool – generally this is because inefficient design principals have been employed. In the vast majority of datacentres, the server rooms are kept exceedingly cold, but the servers sit there blowing out a heap of hot air back into the room. A huge amount of energy is thereby wasted constantly having to re-cool that hot air again, causing the cooling systems to work harder and consume more power than they ought to.
In Centro, the hot air expelled from the servers is contained and directly extracted from the building, meaning the cooling systems can operate much more energy efficiently. The super efficient water-based chillers additionally use ‘free cooling’ technology, which means that when it’s cool enough, the outside air can just be pumped through rather than waste energy keeping the chillers running at full-speed.
Whilst only a small change, we are proud that The Green Web Foundation has awarded us their green web badge & we are part of the green web revolution.
