Australia’s refugee problem has attracted global attention. This from the New York Times.
The carbon footprint of lazy journalism
|
Your Google searches are killing the planet. That’s the story the world’s news organisations are running with today, first appearing in the UK’s Sunday Times with this headline-grabbing intro:
It’s the kind of study that probably made the papers’ tech editors wee their pants just a little bit, combining Google — a perennial favourite in cutting-edge mainstream IT news, along with fawning over new Apple products, Facebook groups and the slightest happening on Second Life — with the hot-button issue of global warming. As an added bonus, the study was done by a Harvard University physicist, Alex Wissner-Gross. Imagine their relief when something like this rolled off the wire at this news-deficient time of year, saving them from having to run yet another report from the Consumer Electronics Show.
Yep, it’s a great little story. But it’s an even better piece of PR, and most papers quite happily reprinted the Times article verbatim, without any apparent extra research into Harvard’s Alex Wissner-Gross, or his business, which they all inadvertently promote.
And in an accompanying Times piece that gives Wissner-Gross even more air-time:
And guess who can help websites do just that? As well as being a Harvard physicist, Wissner-Gross runs a start-up company offering web hosts the chance to calculate their site’s energy consumption and purchase credits to offset its carbon footprint. For a fee, of course. A quick visit to the actual website shows that CO2Stats has nothing to do with the study on Google-search energy consumption, which is the article’s hook (the study isn’t actually published yet); it is simply the site selling Wissner-Gross’s services. As businesses go, making websites more eco-friendly is a pretty positive enterprise. But Wissner-Gross has a definite agenda — not to mention business — to promote in criticising Google’s energy usage, and neither the Times, nor anyone reprinting their copy, bothered to divulge it. The story has been all over the blogosphere, Twitter, and tech sites like Techmeme and Slashdot, and suddenly, everyone’s talking about websites’ carbon footprints. Say, I know a guy that can help you offset that… On the upside, think of all the carbon emissions that are saved by lazy editors and journalists who don’t bother fact-checking PR like this with a few simple Google searches. |

Some facts as I understand them snarfed from the web - corrections welcomed…
rough cost of wholesale energy per kilowatt hour (kwh): ~5c
CO2 cost per kwh: ~1kg (coal power: http://cdiac.ornl.gov/pns/faq.html)
time for my (small) 1 litre (~ 1kw) kettle to boil when full is ~ 5 minutes which compares well with the theoretical energy for a 1litre at ~350kj, or 350 seconds time for 1kw . Hence power for a small boiled kettle is a killowatt for 1/10 of an hour, or 0.1 kwh
So I get…
Kettle boiling: costs ~.5c, and ~ 100g, … the article says a kettle take 15g, which I don’t get even close to; maybe clever people boil just enough to make single cups only?
If the article was true, Google doing “more than 200m” searches a day would spend ~ $20m a day on power, or ~ $7billion a year, consuming 100,000 megawatt hours, or a continuous drain of 4,000 megawatts (about half the power output of Victoria). On the authors figures, total power consumption would be ~ 650 megawatts, which I guess is about the size of Hazelwood, and would still be spending ~ $1billion a year.
Google use cheap, mass produced low power units in gigantic numbers - estimates are hard to come by, I will estimate 200,000 (http://arnab.org/blog/how-many-computers-does-google-have). Energy cost of networking is significant, but I do not believe as great as machines; I’ll add 50% for good luck. Utility server machines are dropping in power (~100-200w) but also require cooling, UPSs and network etc., so we’ll call it 500w all up (figures are difficult to get; everyone is selling something power center wise) - so I get 100 megawatts; or 1/6th of the author’s estimate, or 1/40th of the true kettle figure.
I’d say that the author is overstating the case to make a political point - and I’d have to agree with the main article it might have something to do with promoting his business…
For another deconstruction of the numbers:
