Energy Efficiency in Asia and the Pacific

Feature | 22 August 2012

Energy demand in developing Asia is expected to grow by 2.9% per year to 2035 - faster than the world average of 1.6%, according to the International Energy Outlook 2011. Improving efficiency can help the region meet rising energy demand in a cost-effective and sustainable way. Here are 12 things to know about energy efficiency.
