Should America Follow Europe's Lead On Energy?
Should the U.S. follow other nations' lead in prohibiting certain types of energies and technologies because of their environmental and health risks? Jennifer Morgan responds, "As the United States sorts out its next moves on energy policies to enhance long-term security and strengthen its economy, policymakers will need to weigh both benefits and risks of various energy sources. Looking at what other countries are doing is a good place to start. European countries' recent moves have one thing in common: each is moving to cleaner energy sources and greater energy efficiency."

Our sustainability in operations is dependent on the quality, cost and availability of energy sources. We are also subjected to the various taxation and regulatory schemes which impact the fossil fuel based energy usage and hence in turn impact our sustainability. Additionally, a significant portion of energy is consumed in transportation of raw materials and finished goods.

Energy forms the major part of our operating expenses in upstream operations. We track energy performance at each operating unit and are committed to continual improvement in energy efficiency. We also understand the importance of having a sound energy management system in place and to this effect our subsidiary Novelis has embarked on the process of implementing energy management system based on ISO 50001 standard.

In economies that are amenable to aluminium recycling, we take steps to enhance the use of recycled (secondary) aluminium instead of primary metal extraction which leads to lesser energy consumption in smelting. We are taking innovative steps in reducing our transportation energy consumption by having modes such as direct lift from mines by ropeway and deep sea transport of raw materials and finished products by dedicated closed tube conveyor. We aim to have continuous improvement in efficiency parameters through benchmarking and incremental innovations, effected through the annual plans with stretched targets.

Perform, achieve and trade (PAT) scheme implemented by Bureau of Energy Efficiency (BEE) under National Mission of Enhanced Energy Efficiency (NMEEE) is a mechanism to promote energy efficiency and energy benchmarking of some of our energy intensive units. We consider this as an opportunity and a risk area. As an internal management approach, we take steps in improving our specific energy consumption by technology upgrade and de-bottlenecking initiatives.
