Germany comes in first in a new energy efficiency ranking of the world’s major economies, followed by Italy, the European Union as a whole, China, and France, according to the 2014 International Energy Efficiency Scorecard published today by the nonprofit American Council for an Energy-Efficient Economy (ACEEE). New to the rankings this year are four nations: India, Mexico, South Korea, and Spain. Now in its second edition, the ACEEE report finds that, while some countries are still significantly outperforming others, there are substantial opportunities for improved energy efficiency in all economies analyzed, including the U.S., which ranked 13th out of 16 nations – behind countries such as China, Canada, and India. The new carbon pollution standards for existing power plants proposed this June by the U.S. Environmental Protection Agency (EPA) would be a major stride in the direction of greater energy efficiency in the U.S. There are dozens of other international best practices that the U.S. could implement to improve its score.

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.

There is a rapidly rising energy demand from literally billions of devices that remain “on” but may be used for only a few minutes or hours per day. Currently, the estimate for global electricity wasted in this way by network‑enabled devices is 400 terawatt hours (TWh) per year.
