The latest issue of topos is all about energy. It takes a closer look at how the energy consumption of cities around the world is composed and brings hard-to-imagine dimensions into perspective. About three quarters of global primary energy is consumed by cities. But where does the energy in our urban areas come from and how is it used? These are only two of the many questions that issue 120 of topos tries to answer. For this, topos 120: Energy City lets energy experts have their say and sheds light on how selected cities are implementing their exemeplary energy transition through innovative projects and initiatives. But the issue does not only look at the present. From the beginnings of household electronics to a glimpse into the far future of Mars colonization, the 120th issue of topos offers a broad selection of topics on the subject of urban energy.
