PPEO 2018 builds on PPEO 2016 (bottom-up energy access planning) and PPEO 2017 (financing for energy access) to explore how access to energy can be accelerated to achieve both the scale required to meet the global 2030 goals, and the inclusivity required to leave no-one behind. The report looks at clean cooking, decentralised electricity and grid-extension case study programmes across sub-Saharan Africa, South Asia and Latin America to consider what we can learn from previous approaches and how these two objectives (scale and inclusivity) can be pursued in parallel, to help us deliver on our global goals.
