Articles relevant to Green IT:

Article 1

“Green IT Trends: How the Computer Industry Is Saving Energy”:

Article presents ideas to make computing and manufacture processes more environmentally sustainable. It gives ideas such as usage of new materials (ex. graphene), locating databases in places, where outside air can be used to reduce the energy spent on cooling the equipment or making strategies, such as upgrading equipment for reuse, which can be more efficient than recycling.

Article 2

“Explaining Green Computing”:

Video presenting impact of computing on the environment, examples of solutions to reduce energy and resources consumption .

Article 3

“Energy-aware Internet routing coming soon”:

Article shows idea of algorithm, created by MIT researchers, which manages cost and usage of electricity in huge companies. Algorithm focuses on routing Internet traffic to data centers, where electricity is less expensive and more “eco-friendly” strategies can be developed. At the end it shows another example of use of sensors and other modernizations used to balance the usage of energy.

Individual task after the first seminar

My personal “sustainability movement”, besides implementation of well-known forms of recycling and resources saving, would depend on increasing public awareness in this topic. Creation of new applications or technologies in sustainability has no meaning, until we realize the weight of the subject to the public. Using today's technology we can in easy way create websites, blogs or facebook pages, where we can share interesting ideas concerning this topic, or create our own articles. Moreover, we can try to offer lectures in schools or universities, to influence people from the earliest years of their lives.

Finally, we can create social movements, which could propose laws similar to those presented in this video:

Simple, specific example would be to create act, which would ensure 60% of the country's afforestation. Even if this act would not be accepted by the government, collecting signatures and cooperation with media could change the way of thinking in society.

Questions after course

1) Why measuring sustainability is difficult task? - Establishing appropriate variables is difficult, because of the lack of single definition of sustainability. For everyone it can mean something different, so there are no fixed variables. Also measurement of each of them can be difficult. For example, we cannot clearly distinguish boundaries of one ecosystem from another, because they overlap each other and can contain many smaller ones. Time, in which we want to achieve sustainability in given area, also varies between different cases. For one it can be 10 years and for other 100.

2) What is measured by Cost-Benefit Analysis (CBA)? - CBA measures the proportion between cost of the project and benefits, which it can bring. Other approach to create this SI would be to calculate the cost of restoration of system to sustainable state or expenditures needed to maintain this state.
