Sovacool introduces readers to the injustices and insecurities inherent in the global energy system before presenting an energy justice conceptual framework consisting of availability, affordability, due process, good governance, prudence, intergenerational equity, intragenerational equity, and responsibility. He showcases the application of these principles to eight real-world case studies involving national energy planning in Denmark, the Warm Front program in the United Kingdom, the World Bank"s Inspection Panel, the Extractive Industries Transparency Initiative, São Tomé e PrÃncipe"s Natural Resource Fund, solar energy in Bangladesh, climate change adaptation efforts in least developed countries, and the Yasuni-ITT Initiative in Ecuador.
