Carbon Negative Vodka from Thin Air

Image
More and more stories are coming out about products removing CO2 from the atmosphere. This one is really cool. The carbon on the atmosphere is used top produce alcohol and with that vodka. Carbon negative vodka - brilliant. You can only buy it from their Bushwick factory to keep it carbon friendly. Understandable, but a bit of a shame.

Carbon Footprint Transparency of Lenovo Hardware

Yesterday I wrote about how Dell are reporting on the carbon footprint of their hardware. I definitely do not want to be seen as biased, so here is the equivalent from Lenovo. Personally I find this one not quite as pretty, but it is about the content rather than the looks and in that respect  Lenovo might even offer a little more detail. The most important point for me is that the hardware vendors seem to be taking this subject seriously.

What is PUE???

The Power usage effectiveness (PUE) is a measure of how efficiently a data centre uses energy. Specifically, how much energy is used by the computing equipment in relation to the total of how much energy is used by the total infrastructure. In other words, a data centre with a PUE of 1 is using no energy over and above the servers in it. A PUE of less than 1 is extremely hard to achieve as you would have to create more energy than all the environmental systems (like aircon) use to overall use less power than the servers need. Let's try an example. Lets assume that your server uses 60W. That means that the annual power consumption is 60W x 24 hours x 365 days (at least for no-leap years). That would be 525,600Wh or 525.6 kWh per year. If your data centre has a PUE of 1.5 the overall power consumption of that server is 525.6 kWh * 1.5, which is 788.4 kWh (incl PUE). I hope this makes sense. Either way, please let me know your thoughts.
