The debate on the energy of the future and where it will come from has intensified significantly, and now involves every sector of society. Cost, decarbonization goals, environmental and political factors, energy independence, security, renewable sources, and the “new” nuclear power: these are just some of the key aspects of an issue that is of paramount importance to both industrialized and developing countries. The need for serious, forward-looking planning, beyond the ups and downs of current events, is becoming more pressing by the day. Indeed, the strength of democracy and the well-being of citizens in the coming century will depend in part on each country’s degree of energy autonomy. At the same time, the fair and sustainable distribution of energy is emerging as an essential tool for reducing disparities between the global North and South. Stefano Buono and Antonio Ereditato address these issues with clarity and scientific rigor, avoiding an ideological approach. Their analysis is concrete and open-minded, offering possible scenarios and compelling arguments in clear and accessible language – a message for everyone.
