Book excerpt: This publication i) illustrates how costs and benefits of energy interventions including their impacts along the agrifood value chain can be measured at country level, ii) applies the analysis to 11 country case studies, iii) identifies barriers, possible solutions, business models and success factors for the adoption of energy technologies, and iv) draws general recommendations for investors and decision makers. This report summarizes the analysis and main findings stemming from the FAO project “Investing in Energy Sustainable Technologies for the Agrifood Sector” (INVESTA). FAO has been working together with GIZ and partners of the international initiative Powering Agriculture: An Energy Grand Challenge for Development (PAEGC) since 2014. PAEGC, also partnered by the German Federal Ministry for Economic Cooperation and Development (BMZ), supports the development and deployment of clean energy innovations that increase agriculture productivity and stimulate low carbon economic growth in the agriculture sector of developing countries to help end extreme poverty and extreme hunger.
