Abstract
The article focuses on a German program to improve energy efficiency, called Learning Energy Efficiency Network (LEEN). A network of LEEN is joined by 10 to 15 firms in a region, which collectively commit an energy conservation target. Since the introduction of LEEN into Germany in 2002, the number of networks of LEEN in Germany has been increasing. Today there are about 50 active networks in German. They are reducing energy consumption of participant companies by about 2 to 2.5 % on annual average. The paper analyses the effectiveness of LEEN to remove barriers to energy efficiency, and derives implications for Japanese energy efficiency policy.
