Energy Efficiency — Potential solution for bridging demand supply gap

India has witnessed phenomenal growth in power sector. Installed capacity stands today is about 250GW resulting in per capita energy consumption more than 900 units. However, high GDP growth is coupled with increasing demand for electricity. There is an energy shortage of about 4.3% and peak of 5.4%. Several initiatives have been made to bridge the demand supply gap by Government of India in the past. Increasing capacity addition and renewable energy has helped in large way. It is estimated by Ministry of Power, GoI that about 23% of energy can be saved by adopting energy efficiency across all energy users. This necessitates identification of areas for energy conservation through energy audits as well as implementation of energy efficiency measures. Power Grid Corporation has surveyed the potential in various areas and combined with the experience in audit of energy intensive industries as well as other commercial establishments brings out the practical view point to adopt energy efficiency that are discussed in this paper.
