Today on (Dec 20, 2022)  in the presence of the head of departments and lecturer a symposium entitled (Green Computing), was presented by the Assistant Lecturer (Mr. Saif Saad Alnuimi) from the Computer Science department, Where it has been explained about The need for the concept of green computing to obtain more technology and modern technologies in the industrial area and maintain it. The ethical commitment to the environment and climate should not be separated in any way from the desire to develop and innovate the latest technologies to facilitate people's daily lives. Through technologies such as the Internet of Things (IoT), computing technologies of all kinds, data centers, and technologies that many parties use to implement operations related to these technologies, but it is necessary to take into account the impact of the work of these technologies on humans and the surrounding environment, and reduce the risks of these devices to the extent that these effects as possible. Green computing is still being developed, and this work is still being done collectively. Microsoft has experimented with using submarine technology to test an underwater data center in order to benefit from marine renewable energy as a primary source of energy, which eliminates the need for external cooling equipment for these resources. This is done in light of the fact that many organizations promote responsible environmental work and the trend towards environmentally friendly business, as well as by supporting the idea of green computing, At the end of the symposium, a set of questions and answers were raised on this subject
