In this second edition of the International Energy Efficiency Scorecard, we analyze the world’s 16 largest economies, comprising more than 81% of global gross domestic product and about 71% of global electricity consumption. We looked at 31 metrics, divided roughly in half between policies and quantifiable performance, to evaluate how efficiently these economies use energy.
Our results indicate that some countries are significantly outperforming others, but the more important finding is that there are substantial opportunities for improvement in all the economies analyzed. The conditions required for a perfect score are currently achievable and in practice somewhere on the globe. For every metric, at least one country (and often several) received full points. However, every country also has serious weaknesses, and the average score was just 50 points.
