Shopping malls, supermarkets, boutiques, restaurants and banks are some of the major commercial establishments that demand a large chunk of the energy supplied by electricity and gas companies for heating and lighting. Eco-friendly practices and energy-saving appliances, combined with smart design to maximize the use of natural light can lead to an appreciable change in the energy usage of these establishments. Restaurants and hotels adopting greener options like rain water harvesting and solar heating save on utility bills in the long run. Water conservation, recycling gray water, and xeriscaping are some of the easy options available.
