This book follows on from the first, Regards sur l'Algérie - Energie et Rente. It deals with concepts that are often overlooked when dealing with energy issues. Energy transition is a global concern, given global warming and current production and consumption patterns. Energy transition must be a joint effort between a government and its population. The case of Algeria is the subject of this content. The transition in Algeria is multifaceted. It is political, with new governance; it is economic, with the diversification of exports; it is social, with actions in housing, health, food security and the fight for decent purchasing power; it is energy, with a global strategy in line with the commitments made at the various Conferences of the Parties. Saving the planet is everyone's business, and Algeria is doing its part to adapt and rise to the challenge with actions that match its ambitions.
