The "2015 Energy Productivity and Economic Prosperity Index" ranks countries
based on their economic output per unit of energy consumed. Commissioned by
Philips, Ecofys created the index together with The Lisbon Council and
Quintel Intelligence. It gives an overview of the current energy efficiency
performance of countries, but also presents scenarios for the European Union
and six individual countries: France, Germany, the Netherlands, Poland, Spain and the United Kingdom.
