Green IT is studing and practice of using computers and IT resources in more efficient and environmentally responsible way. Because use of computers and computing eat up lot of natural resources, from the raw materials needed to manufacture them, the power used to run them, and the problems of disposing them at end of life.
There are many ways to practice green IT which includes for example building computers with more environmentally friendly materials, designing them to be consume less energy, providing recycling programs to dispose of old systems, developing virtualization and cloud computing alternatives, and providing tips to businesses that want to go green.
How to increase sustainability aspects in LUT CS/SWE programme
Basically what we could do first to increase sustainability aspects in LUT CS/SWE, is to increase the students awareness of green IT and sustainability. Then we can assure that students are aware of doing things and increasing sustainable aspects. For example if consumer doesn't know that product he bought is recyclable, why he would recycle it then. Awareness can be raised by offering certain courses like this one. Also lots of practical solutions and implementations can be teach to students in many IT courses, specifically in coding, when lecturers give coding examples and solutions, which cause only little burden to computers. Making too heavy programs for computers to complete causes increased need for processing power and energy.
1. Define Green IT and give 3 examples of practicing it.
This question is meant to ensure that student has at least read and learned something about the topic from books and seminars.
2. Why cloud computing is considered environmentally sustainable in IT and does it have any negative issues or challenges. If does, list and explain them briefly.
This is quite huge question, but because cloud computing has gained immensely interest as sustainable IT solution, students should understand, not only benefits but also possible negative issues or challenges of clouds. These are for example security issues. Deploying new sustainable technology may be green, but it can also cause problems.
3. Which one is more sustainable, change people who buy product or change product that people buy? Choose and explain why?
This is good exam question, because it puts students to think the situation from many ways and raises more interesting questions about choosing more effective sustainable action. Would it be more effective and sustainable to concentrate on teaching people to behave more sustainable way; by teaching them for example to buy less and wasting less energy when using products? Or making products more and more recyclable and production more resource efficient? Even though we could make 100% recyclable product, which is practically impossible, will people bother to recycle it. The question about products lasting long and how often people change cellphone or buy new computer was raised in the 3rd seminar. Of course both changing people and products are important, but this question puts students to critically think their options' pros and cons more closely.
4. Describe briefly three solutions to improve IT sustainability in universities and list what benefits they could offer.
This question is mainly for students to think and adapt their knowledge of the course material and seminars to practical situations. The knowledge is useless if you cannot utilize it.
