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.
