A country that uses less energy to achieve the same or better results reduces its costs and pollution, creating a stronger, more competitive economy. While energy efficiency has played a role in the economies of developed nations for decades, cost-effective energy efficiency remains a massively underutilized energy resource.
In this second edition of the International Energy Efficiency Scorecard, we analyze the world’s 16 largest economies covering 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. The policy metrics were scored based on the presence in a country or region of a best-practice policy.
