This chapter considers the use of input-output (IO) to conduct gross or net assessments of the socioeconomic implications of renewable energy deployment. The use of IO methodology extended with environmental and socioeconomic vectors has been proposed as a framework for analysing the sustainability of energy investments, as it is able to capture the total, direct and indirect, impacts of energy investments, considering the phenomenon of global value chains both in environmental and socioeconomic terms. This chapter describes the IO methodology and its extensions and discusses the scope of its applications to renewable energy investments.
