Thomas Wiesel reacts cynicism and humour to failure to vote for the CO2 initiative in Switzerland, in popularizing, in his own way, the conclusions of the recent IPCC report (Intergovernmental Panel on Climate Change) on the state of the climate crisis. And he is focused on one of François Maréchal’s studies entitled Decarbonization in Complex Energy Systems: A Study on the Feasibility of Carbon Neutrality for Switzerland in 2050. (Maréchal is with the École Polytechnique Fédérale de Lausanne).
Briefly, that study envisions a model city that consumes less energy based on a circular system that, among other things, proposes using and reusing energy efficiently, effective energy conversion as well as integrating renewable energy sources.
Summary of the video study
Today cities account for 40% of greenhouse gas emissions. Yet thermodynamics shows us that heating and cooling building should only use 10% of what they consume now. In using CO2 in an urban heating network, it would be possible to heat and cool the centre of Geneva using only 16% of what is currently consumed. Fuel cells can convert gas to electricity and capture CO2. With solar energy, CO2 and water combine to produce gas and the waste we produce can be converted into heat and electricity. By integrating them all, you can render the city self-sufficient.
