About this data
Energy intensity level of final energy (MJ/2011 USD PPP): A ratio between final energy consumption and gross domestic product measured at purchasing power parity. Energy intensity is an indication of how much energy is used to produce one unit of economic output. Lower ratio indicates that less energy is used to produce one unit of output.
