gallons a load‚ while most top-loading machines‚ unless they are energy-efficient‚ use 40 gallons per load. * Nearly 22% of indoor home water use comes from doing laundry. Save water by making sure to adjust the settings on your machine to the proper load size. * Dishwashing is a relatively small part of your water footprint—less than 2% of indoor use—but there are always ways to conserve. Using a machine is actually more water efficient than hand washing‚ especially if you run full loads.

An electricity board generally constitutes of three modules: Generation‚ Transmission and Distribution. The state electricity board of Delhi was broken into the above segments in 2002. Generation went under several corporations like IPGCL‚ BTPS etc. Transmission came under DTL‚ and Distribution was controlled by BSES (Rajdhani‚ Yamuna‚ NDPL). An Electricity Act was introduced in 2003 for reasons of increased control and reduced theft. This act required each state to modulate its electricity board
