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.
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 sustainable IT technology and does it have any negative effects or issues. 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 effects of clouds. These are for example security issues. Deploying new sustainable technology may be green, but can cause other problems.
3. Which one is more sustainable, change people buying products or change product that people buy? Choose one and explain why? The question about products lasting long and how often people change cellphone was raised in the 3rd seminar. 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 efficient? Even though we could make 100% recyclable product, which is practically impossible, will people bother to recycle it.
