4. Conclusion
The major concern that arises after looking at the data is whether the country is using the energy optimally. To
address such concerns we need to decompose the energy consumption unit into its constituent sectors and then
analyze the decomposed energy sector for its energy consumption, energy intensity or CHG emissions. The
Index Decomposition Analysis is a simple but apt technique to address this problem and will help the
government to plan policy in a better way so as to achieve the planed targets.
The present work was just a discussion on IDA, its methodologies and its attributes based on the comparison
done by Frederic Granel in 2003 on various IDA methods. In view of the tool i.e. available to us, we can in
future decompose the energy consumption of India, where wastage of energy is a key problem. We may able to
identify the aggregate energy indicators and then help plan the policy to conserve energy and waste less.
End Note
The IDA in its present form is the work of distinguished Prof. Ang Beng Wah of NUS, Singapore. He has
authored many papers and technical notes in international journals on the subject and also guided many PG and
doctoral students. Today the Industrial and System Engineers owe most of the findings related to new techniques
of IDA to him. The equations and text related to IDA, used in this paper has mostly been referred from Frederic
Granel’s doctoral thesis submitted in 2003.
