The electricity consumption per capita in Ecuador almost doubled between 1999 and 2017. Although electricity, gas and fuels are subsidized by the state, and thus generate savings for users, this often leads to inefficient use or bad energy consumption habits in the population. The current economic situation in the country has urged reconsidering th...
