Watch Mapping the World Season 35 Episode 17 Online

In a world where climate change is accelerating, wind and solar power seem more than ever to be the energies of the future. This week, "Le dessous des cartes" lets you discover how these resources, used for thousands of years, are being brought back into fashion in the 21st century. From India to Denmark, via China and the United States, large-scale renewable energy projects are multiplying. As a result, the share of wind and solar in the global electricity mix has exploded in recent years. All the more so since the costs of wind turbines and other solar panels have fallen considerably, in particular because China has invested massively in this industry, managing to slash prices and sell its components to the entire world. Enough to make renewable energy an ecological issue first, and a geopolitical issue second, for better or for worse.
