The report underscores the urgent need to transform global energy systems so that the world’s population has access to energy based on renewable sources. This is necessary in order to protect the global climate and to liberate 2.4 billion people in developing countries from energy poverty. Such an approach would also yield a peace dividend by reducing dependence upon regionally concentrated oil reserves. The scientists stress that such a reconfiguration of energy systems is feasible and fundable if rapid and resolute action is taken in the coming two decades. To this end, they propose a roadmap with specific milestones.
