This concluding chapter discusses the main lessons emerging from the work contained in this book. Key results pertaining to the empirical analysis conducted, together with observations on the methods used are presented. It acknowledges the difficulties of conducting research that transcends some established methodological boundaries and presents the main limitations of the research in this context. While some of the key findings from the analysis presented in previous chapters are revisited and main achievements highlighted in this chapter, it does not present a comprehensive summary of all the results. The chapter is organised in three sections. The first provides some general conclusions from the empirical part of the research. The key findings of applying a household perspective to study energy consumption in the Indian scenario are also discussed and some general reflections and implications of the work are presented. In the second section, the general findings, from the application of the different methods to the Indian data and situation, are highlighted. The main methodological limitations, largely pertaining to data availability and quality, are also discussed. Finally, the last section presents the scope for future research in this field.
