The United Nations with its SDG 7 indicate that by 2030 universal access to affordable, reliable and modern energy services must be ensured. The share of renewable energy in the global energy mix should be substantially increased and the rate of energy efficiency is to be doubled in the same time frame. In the Mosul region as in many other regions of the world, we are far from achieving these goals. In our student workshop we will explore and tackle this problem from multiple perspectives: We will discuss the importance of raising awareness for renewable energy and energy efficiency (REEE) in our society. We will be learning about the scientific and technological foundations of renewable energy such as solar power and energy-efficient building. An additional focus will be on the design of a more sustainable cooling and heating system, which could be applied in Mosul. Based on this knowledge we will develop our own visions for improving the energy supply in our region in a sustainable and modern way. We will present and discuss our visions with others on the final conference day. The workshop is open for students of all disciplines and especially relevant for students of natural sciences (physics, chemistry, biology), environmental sciences, spatial planning, architecture, engineering and related subjects.
