Despite the development of alternative energies, coal still plays an important role in the world's energy supply. With its excellent caloric efficiency, it is also a very polluting fossil fuel, responsible for half of the carbon dioxide emissions produced by the energy sector.

There are 7.6 billion human beings on Earth, with a growing proportion of young people, unequally distributed. Does this mean that the migratory rush from the south to the north is inevitable?

Water is essential to life, which makes it eminently precious. What are the planet's resources of 'blue gold'? Are we in danger of running out? Focus on the strategic stakes of a very unevenly distributed resource, and mapping of the geopolitical conflicts it provokes.

Since the development of Alan Turing's message decoding machine, artificial intelligence has made enormous progress. Today, it is used in software for traders, household robots, digital assistants and, tomorrow, autonomous cars. We take a look at the states and digital giants that have taken the measure of the formidable…

If our planet is a Tower of Babel where nearly seven thousand languages are spoken, some linguists agree that nearly half of them will have disappeared by the end of the century. Sources of conflict (Catalonia, Crimea...) and power issues, languages have become a geopolitical subject.
