This article investigates activities at the local, national, and supra-national levels that are aimed at reducing energy poverty. The authors argue that efforts to reduce energy poverty have been in use for decades and that policymakers should draw from this wealth of experience when developing solutions to energy poverty in their locales. The main areas of analysis are policy, investment promotion/financing, utility regulation, and business development. The study presents 20 principles extracted from an analysis of 13 country case studies.
