A multidimensional Sustainable Energy Security (SES) index is developed. The SES index evaluates the performance of the energy demand sub-system using 23 metrics. Dimensional indices are calculated for 2002, 2007 and 2012 for various sectors for India. The aggregate demand sub-system SES index shows an increase by 10% from 2002 to 2012. The index is 30% short of the target implying a large scope for improvement.
