Enhancing energy efficiency to increase affordability: evidence from residential lighting retrofit in Peru

In this paper, we discuss the Peruvian retrofit lighting program that was part of the National Energy Plan 2014-2025. Using data from the Residential Survey on Consumption and Uses of Energy or Encuesta Residencial de Consumo y Usos de Energía (ERCUE) for the waves 20142015, 2016, and 2018, we find that households have greatly benefited by replacing incandescent light bulbs with energy-saving and LED bulbs between the year of implementation of the program, and 2018.
