Telehouse London switches to 100% renewable energy

Last week data centre company Telehouse announced that it's London Docklands data centre site ‘now purchases 100% renewable energy’ from UK provider SmartestEnergy. The data centre houses the IT infrastructure of almost 500 major international organisations.
SmartestEnergy is the UK’s leading purchaser and supplier of electricity from independent generators. The renewable energy it provides to Telehouse comes from projects throughout the UK using a variety of sources including wind, solar, hydropower and anaerobic digestion.
It’s a further step for Telehouse in its commitment to reduce its carbon footprint. The Telehouse London sites have already been awarded the Carbon Trust Standard, which certifies that an organisation has measured, managed and reduced its carbon emissions across its own operations and is committed to further reductions in the future.
Tokuji Mitsui, managing director of Telehouse and KDDI Europe, pointed out that "The majority of electricity supplied to us is utilised by our clients, therefore it is integral that we take on initiatives such as the 100% green energy supply, which in turn benefits our customer's credentials by reducing their carbon footprint. We intend to roll out this green partnership initiative with SmartestEnergy to all our European sites in the near future."

Well the press release is not absolutely clear. Some energy may be 100% renewable (in the UK ‘green’ energy is sometimes only that with a high renewable proportion), but it may not mean that all your energy comes from renewable sources. In this case, though, it does seem that Telehouse London now only uses renewable energy.
It will certainly make it easier for customers to assess their ICT carbon footprint with the knowledge that there are no Scope 3 (indirect) emissions from this part of their external service delivery. Among the sort of customers that Telehouse has, the question about supplier emissions will certainly have started to be asked.
