Green IT3: Sustainability Indicators

Here are some articles that I found about Green IT:

  • short article about the basics of green IT. (requires LUT access)

  • The authors, Harmon & Auseklis list here the factors that drive the adoption on green it:

1. growth of the internet, 2. increasing equipment power density, 3. increasing cooling requirements, 4. increasing energy costs, 5. restrictions on energy supply and access, 6. low server utilization rates, 7. growing awareness of IT's impact on the environment

  • Some strategies on reducing the impact on environment:

1. data center infrastructure, 2. power and workload management, 3. thermal load management, 4. product design, 5. virtualization, 6. cloud computing and cloud services

Hoover, J. 2008. 10 Ideas to Power up Your Green IT Agenda, Information week, issue 1203.

  • interesting short article with 10 facts on green IT. Practical examples what famous companies are doing with sustainability issues.

I succesfully took the survey that was linked in Noppa page.

I finished the course META101x: Philosophy and Critical Thinking

Individual task after first seminar:

Design a new “sustainabilility movement” starting from small individual actions and advance to societal impact. The purpose of this is to find concrete action for example in waste management, enargy usage, …. Present how the action could be expanded to society movement (like the whole village would participate in waste management). Deadline by the second seminar time.

My personal sustainability movement would be called “Take a look at your closet”. Now seriously, go and take a look at your closet and count how many pieces of clothing there are. While doing this you may find that the majority of those clothes have not been worn in ages. That's a simple result of clothing stores' aggressive marketing tactics and sales that make you buy things that you don't need in addition to the fact that it is on the manufacturers intrest that the clothes you buy are soon out of fashion. If you end up owning too many clothes, you can't get a grip of what your closet actually contains as it's so fully stuffed. The solution to this is usually to acquire more closet space or more spacious clothing room, as the reaction should be the opposite: downsize your wardrobe! What clothes should I recycle then? -you might ask. Well the answer to that are given to you by your smart phone and a Closet Control -application!

The application might not exist yet, but the idea and the technology behind it is simple. The application uses small unnoticeable RFID-tags that you install on the each of your clothes. RFID-tags are very cheap nowadays (few cents a piece) since they are widely used on the market. Many smart phones also has a NFC-reader already installed on it, so the technology to read the tags is already on your pocket. Once your closet is setup with the RFID-tags, you simply “scan” your clothes near your phone so that the Closet Control -app knows what you're wearing. As the time goes by, the app can show you your closet just as the companies follow their inventory levels: what is the cycle time of each piece of clothing etc. The app can then reveal if your closet contains stuff that you don't use, and it can suggest you to recycle them. You can also set a maximum capacity to your closet, and if you buy a piece of clothing and try to add it to your closet, the application will notify the user on this until some of the unused clothes are recycled.
