Washington, Jul 18 (EFE).- Germany leads the principal world economies in energy efficiency, followed by Italy, China and France, a report released by the American Council for an Energy-Efficient Economy says.
For its part, the United States takes 13th place, according to ACEEE's 2014 International Energy Efficiency Scorecard.
ACEEE researchers focused on 31 metrics across four categories: aspects of energy use at the national level, buildings, industry and transportation.
China leads in efficiency in buildings, Germany in industry and Italy in transport.
One surprise of the report, which is published every two years, is the low rating given the world's No. 1 economy - the U.S.
"The United States, long considered an innovative and competitive world leader, has progressed slowly and has made limited progress since our last report, even as Germany, Italy, China, and other nations surge ahead," ACEEE Executive Director Steven Nadel said.
Noted as factors contributing to the low U.S. score are the little use and low investment in public transport, the many miles traveled by comparatively inefficient vehicles, as well as high energy consumption in homes and businesses.
The 16 economies analyzed represent 71 percent of global energy consumption.
