Cloud Computing: Google Apps cloud has a relatively high carbon intensity

Cloud
I have been researching and publishing on Cloud Computing for quite some time here. Specifically, I’ve been highlighting how it is not possible to know if Cloud computing is truly sustainable because none of the significant Cloud providers are publishing sufficient data about their energy consumption, carbon emissions and water use. It is not enough to simply state total power consumed, because different power sources can be more, or less sustainable – a data center run primarily on renewables is far less carbon intensive than one that relies on power from an energy supplier relying on coal burning power stations.

At Greenmonk we believe it’s important to get behind the headline numbers to work out what’s really going on. We feel it’s unacceptable to simply state that Cloud is green and leave it at that, which is why we’ve been somewhat disappointed by recent work in the field by the Carbon Disclosure Project. We would like to see more rigour applied by CDP in its carbon analytics.

Carbon intensity should be a key measure, and we need to start buying power from the right source, not just the cheapest source.

I was pleasantly surprised then yesterday when I heard that Google had published a case study ostensibly proving that Cloud had reduced the carbon footprint of at least one major account.

However, it is never that straightforward, is it?

The Google announcement came in the form of a blog post titled Energy Efficiency in the Cloud, written by Google’s SVP for Technical Infrastructure, Urs Hölzle. I know Urs, I’ve met him a couple of times, he’s a good guy.

Unfortunately, in his posting he heavily references the Carbon Disclosure Project’s flawed report on Cloud Computing, somewhat lessening the impact of his argument.

Urs claims that in a rollout of Google Apps for Government for the US General Services Administration,

the GSA was able to reduce server energy consumption by nearly 90% and carbon emissions by 85%.

An 85% reduction in carbon emissions sounds very impressive – but how does Google calculate that figure?

The rise of the energy manager role

One of the topics which I responded to on the recent IBM Eco Jam was “IT’s Central Role In Managing Energy & Carbon”.

This topic was raised by another analyst (again IBM has asked me not to mention participants by name but if the analyst in question sees this and wants me to name him/her, I have no problem so doing) when s/he posted the following:

Forrester’s research on energy & carbon management systems predicts that IT organizations will take on a central role in choosing, owning, and operating these systems. The challenge of managing energy & carbon emissions will increasingly be information-related, and it’s enterprise IT organizations that have the expertise to install and operate software systems of record across the entire company. Just like systems for managing customers (CRM), money, materials (ERP), and employees, carbon & energy management systems will collect, integrate, analyze, and report on the newest set of assets/liabilities that will be used by internal and external stakeholders to judge corporate performance.

Now, I have no issues whatsoever with IT organisations having a role in choosing Energy Management systems. IT’s function would involve installing and supporting the software so naturally they’d have a say in its purchase. They’d also have a role in crafting requirements documents and reviewing responses but “owning and operating” these systems? I don’t think so.

I realise part of this has to do with empire building ambitions by IT but really, since when was energy management a core competence of IT?

I absolutely realise that sustainability is all about information and data, and certainly IT has a role in ensuring that this information is always available but asking IT to own and operate energy management systems is, frankly, ludicrous. You might as well ask IT to own and operate the financial management systems.

So if not IT, who then should run these systems? I foresee the rise of a new role – the Energy manager, in companies. The Energy manager will likely report to the CFO, the COO or the CSO (Chief Sustainability Officer). The energy manager’s role will be to minimise the company’s energy (& probably water) footprint and to report savings in monetary, kWh and tons CO2.

With the increasing regulatory landscape around carbon emissions (i.e. the Carbon Reduction Commitment in the UK), carbon measurement and reporting will become mandatory for most companies. In that environment having someone specialised in energy management, responsible for this function will start to seem like a very good idea.
