The document discusses proposed energy saving and efficiency interventions for the municipal administration of Padua, Italy. It analyzes the dimensions and inefficiencies of current electrical and thermal consumption across various sectors, including public lighting, buildings, transport and renewable energy. It proposes interventions around efficiency, energy saving and renewables, and evaluates the economic and environmental impacts. The methodology involves analyzing the current state, defining consumption indicators, estimating costs and returns of investments, and evaluating economic and environmental impacts.
