    Green Attack On Facebook: Unfair, But Could It Help? Facebook has responded to criticism of its data centre strategy - and it seems Greenpeace isn’t being fair. But maybe that’s not the point. The Greenpeace campaign has got legs. The environmental campaigner has asked Facebook to “unfriend” coal, after it signed a long-term power deal with a PacificCorp, a utility that makes the majority of its power from coal. Facebook apparently doesn’t have a public green policy, and Greenpeace says it’s not as green as Yahoo or Google.

  6. Carbon footprint of a Tweet, Energy/Tweet approx 100J, CO2 0.02 grams

    Carbon footprint of a Tweet, Energy/Tweet approx 100J, CO2 0.02 grams Every time you send out 140 characters over the social application Twitter, how much energy does that consume? According to some back of the napkin calculations from Raffi Krikorian, a developer for Twitter’s Platform Team, each tweet sent consumes about 90 joules. That means each tweet emits about 0.02 grams of C02 into the atmosphere. For the roughly 50 million tweets sent on average per day, that’s the equivalent of 1 metric ton of CO2 per day. (1 metric ton of CO2 looks kinda like this). Raffi Krikorian's passionate talk on energy use of a tweet starts at 2:50 into ...

    How Much of Twitter’s $100M is for Servers? One of the hottest tech stories last week was the $100 million raised by Twitter in a new round of funding, which reportedly values the microblogging service at $1 billion, even though it has yet to generate meaningful revenue. Much of the commentary has focused on the high valuation, but the funding begs another question: Did Twitter raise $100 million because it can, or because it really needs the money?
