<p>Taking care of how you maintain your gadgets at home can go a long way in conserving energy, writes G Nagaraj</p>.<p>Latest technological developments in appliances and electronics have changed our energy consumption habits. One may not realise it but the energy use of electronic equipments at home often goes unnoticed. A significant percentage of electricity used in our homes can be attributed to the buzz of electronic devices, often consumed by home appliances, <br />entertainment systems and home office equipment. Reports suggest that the domestic sector accounts for 30% of the total energy consumption in the country. Small energy users, including portable devices with battery chargers, also end up contributing a significant share, not because they use a lot of energy individually, but because of their sheer numbers.<br /><br />While in the US, the Department of Energy works with the Environmental Protection Agency on Energy Star, a programme designed to help consumers lower their energy costs by using energy-efficient products, in India, the Bureau of Energy Efficiency (BEE), established by the Ministry of Power, has set up a comparative star labelling system for indoor appliances. This provides information on energy usage to consumers, enabling them to reduce energy bills.<br /><br />This comparative star labelling system is used on indoor appliances like tubular fluorescent lamps, refrigerators (frost-free and direct cool), and air conditioners, along with appliances like electric geysers etc. More the number of stars, more is the energy efficiency of the appliance.
