Energy, what are we talking about?<\/strong><\/h2>\n\n\n\n

Energy is a key sector for our societies. As a factor in the development of civilisation, energy takes various forms (nuclear, chemical, electrical, etc.). It comes from different sources (coal, oil, uranium, wind, etc.). Indeed, it is used on a daily basis to meet our needs (heating, transport, food, etc.). However, the production of this energy also has negative effects that must be kept in mind in order to better mitigate them.<\/p>\n\n\n\n

The challenges surrounding energy efficiency at the University of Lorraine<\/strong><\/strong><\/h2>\n\n\n\n

Environmental impact<\/h3>\n\n\n\n

The first obvious issue, as mentioned above, is the environmental impact associated with energy use<\/strong>. For the 2023\/2024 academic year, if we focus solely on GHG emissions, the university’s energy consumption resulted in the release of 8,600 tonnes of CO2 equivalent, or 200 marathons per user of the Harry Potter films in streaming (if that doesn’t make you know all the lines\u2026).<\/p>\n\n\n\n

Financial impact<\/h3>\n\n\n\n

The second is financial<\/strong>. Due to the size of our establishment, our energy costs are high. The university has seen a drop in consumption <\/strong>thanks to the work of various university departments (building renovations, awareness campaigns, purchasing more energy-efficient equipment) and everyone’s efforts to adopt good habits<\/strong>!<\/p>\n\n\n\n

Nevertheless, we note that the overall cost continues to rise<\/strong>. It reached \u20ac16.3 million for the 2023\/2024 academic year, an increase of 58% in four years<\/strong>. This is due to high energy price inflation. Without the efforts made, we would have spent more. A 58% increase in four years. This is due to high energy price inflation. Without the efforts made, we would have spent more. Without the efforts made, expenditure would have been even higher. These savings represent resources that the university can devote to research or to maintaining and improving the working and study conditions of the university community.<\/p>\n\n\n\n

Regulatory<\/h3>\n\n\n\n

Finally, the last challenge is regulatory<\/strong>. As a public institution, our university is subject to the tertiary decree, which requires us to reduce the final energy consumption of our buildings larger than 1,000 m\u00b2 by:<\/p>\n\n\n\n
