This report offers the vision of a different future - a revolution in development thinking that could see poor regions using renewable energy to power a new and clean era of prosperity. The report analysis focuses on sub-Saharan Africa - which has the highest concentration of the world's poorest people. By using Kenya as a case study, the report examines how climate change is fuelling violence in drought-hit areas. The report also looks at Bangladesh, where virtually the entire population is precariously perched just above sea level. Predicted rises in this level would leave millions displaced and dispossessed.
