Énergie et climat : défis et innovations

Access to energy is a key factor in the economic development of countries. We will first examine the evolution of different ways to access to energy and their correlations with world population and countries’ GDP. We will see that the objectives of reducing carbon dioxide emissions which require a profound transformation of our access to energy will be very difficult to achieve. We will also see that the thermal improvement of buildings, and in particular the renovation of existing housing, is one of the possible objective. Mots-clés.
