 +**"Green IT Trends: How the Computer Industry Is Saving Energy":​** http://​www.wfs.org/​blogs/​len-rosen/​green-it-trends-how-computer-industry-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 presents ideas to make computing and manufacture processes more environmentally sustainable.

 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. Article shows idea of algorithm, created by MIT researchers,​ which manages cost and usage of electricity in huge companies.

 +==== Task missing lecture (lecture 2) ====
 +
 +Review of chapters 1, 2 and 3 from '​Sustainability Indicators'​ book: {{:​courses:​ct60a7000:​spring2016:​green:​indicators:​sustainability_indicators_-_review.pdf|}}
 +
 +==== 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:
 +
 +https://​www.ted.com/​talks/​tshering_tobgay_this_country_isn_t_just_carbon_neutral_it_s_carbon_negative
 +
 +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.
 +
 +==== Group task after the second seminar ====
 +
 +Radar diagrams of countries: {{:​courses:​ct60a7000:​spring2016:​green:​indicators:​radardiagram.pdf|}}
 +
 +==== Individual task after the third seminar ====
 +
 +For the purpose of this exercise I decided to create radar diagram for theoretical house resources management. Indicators depend on three pillars:
 +
 +** 1) Environmental Pillar Indicators: ** Waste management, electricity usage, water usage, heating management.
 +
 +** 2) Economic Pillar Indicators: ** Profits, infrastructure.
 +
 +** 3) Social Pillar Indicators: ** Satisfaction of residents.
 +
 +{{:​courses:​ct60a7000:​spring2016:​green:​indicators:​house_-_si.png?​700|}}
 +
 +Easiest way to achieve above goals is to implement '​Smart-House'​ system. Moreover it is important to educate the residents about the necessity of the sustainability and how huge impact on environment have their actions.
 +==== 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.
 +
 +
 +** 3) What are main differences between '​blueprint'​ and '​adaptive'​ project approaches? ** - '​Blueprint'​ approach tends to be reductionist,​ while '​adaptive'​ is more holistic. '​Adaptive'​ approach can be compared to ongoing transformational process, where feedback is considered at every stage of project. Traditional approach tends to just convert inputs into outputs, while '​adaptive'​ one focuses more on realization of project objectives.
 +
 +** 4) What is the purpose of finding reference-point while creating Sustainability Indicator? ** - Finding such state of equilibrium is necessary to properly measure considered factors, while crating SI. It can be point, in which impact of humans on environment was significantly smaller. Such point can shows us, if we are going in the right direction, while implementing sustainability.
