My guest on this podcast is Strato’s Executive Director for Information Technology and Innovation Rene Wienholtz.

Strato are Europe’s second largest hosting company and Strato are also carbon neutral! Amazingly they achieved this without buying any offsets. How did they do it?

Listen to René explain it.

Here are the questions I asked René and the approx. times I asked them:

Can you tell us something about your own background first and who are Strato? – 00:34

If I heard you correctly you are now the largest hosting company in Europe? – 02:28

You guys are a bit like RackSpace in the sense that you don’t do co-location, you rent space on your servers, id that right? – 02:38

You mentioned that you decided to re-architect the setup in Strato and reduce your carbon footprint, was this for environmental reasons or business reasons? – 03:34

Questions from readers:

Jiri Ludvik
what percentage in carbon reduction they achieved by each of the step you mention? – 05:48

Do you use underfloor plenums as well to direct the air to the cold aisles? – 21:47

Can you talk to us too about the energy savings you are getting from buying CO2 free energy? – 25:44

Have you negotiated a set price from your clean energy supplier for a set period? – 29:36

Can you tell me how long this price is guaranteed for? – 30:15

Have you had any independent 3rd party certify that you are carbon neutral? – 30:27

More questions from readers:

Jim Hughes
Has the carbon saving had a real cost benefit? Or have the lower power costs been exceeded by the premium for carbon neutral electricity? – 31:42

Would you recommend other hosting providers take the same route? – 32:53

Do you think environmental awareness is an area where European hosting companies have a head start over the US? – 34:47

Despite being Europe’s second largest hosting company, Strato are also carbon neutral!

They didn’t achieve this by purchasing offsets either. Strato did it by:
1) purchasing energy efficient hardware
2) using very precise cooling methodologies
3) using customised software to run its facilities and finally
4) by buying CO2 free energy from NaturEnergie.

Strato’s Executive Director for Information Technology and Innovation is Rene Wienholtz and I will be chatting to him tomorrow morning asking him how a hosting company, typically a massive power sink, can go carbon neutral.

If you have any questions you’d like me to put to Rene in the podcast, either leave them in a comment on this post, or email them to me ([email protected]).
