This Element focuses on Latin American fossil fuel producer countries and how they are dealing with the transition towards a greener energy matrix. The challenges involved are multiple and ethical in substance. In particular, a worldwide expansion in clean energies would reduce climate change, physical risks. A rapid transition, however, induces the irruption of a new (financial) risk. The energy transition, in addition, could be thought of as a new arena for political disputes. Finally, it evaluates the relevance of monetary policy and financial regulation to tackle the issue from a macro perspective. Energy transition, however, have also long-term but uncertain consequences on the national economy. Henceforth, and in order to minimize risks, a long-term, strategic vision of the challenge confronted by the region becomes mandatory. To tackle all these problems, this Element profits from contributions of different disciplines.
