Why don’t we measure energy consumption for the world’s poorest?
This is because they often use very little commercially-traded energy sources (such as coal, oil, gas, or grid electricity) and instead rely on traditional biomass – crop residues, wood and other organic matter that is difficult to quantify. This means we often lack good data on energy consumption for the world’s poorest.
