11. Energy Management  Addresses high Energy intensive sectors  Formulation of energy saving plan ● Load management ● Implementation of power saving devices ● Usage of standard devices ● Mandatory Testing / Certification of Electrical Appliances ● Mass awareness through Press & Electronic Media

12. Energy Conservation in India In India, government has passed an energy conservation bill, 2010 for better utilization of energy and conservation. In India, government has passed an energy conservation bill, 2010 for better utilization of energy and conservation. By this act, it is mandatory for energy intensive sectors to get their “energy Audit "conducted by accredited energy auditor.
