Activity

(1) Salma’s class took up an active campaign to do an energy audit of their school by surveying electricity consumption. They prepared survey sheets for the students of the school.
Using the data collected during the survey, students calculated the units consumed for one month and the approximate expenditure and compared it with the electricity bill of the previous month. They also calculated the approximate cost of electricity consumed by fans’ lights and other appliances not switched off. Thus, they highlighted the amount that could be saved and suggested simple energy conservation habits like

  • Switching off the appliances when not in use.
  • Minimal usage as per requirement.
  • Maximizing the use of natural breeze and light by keeping the windows open.
  • Keeping the lights dust-free.
  • The appropriate maintenance and usage of appliances as per the given instructions.

Can you add some more tips to this list?
You could conduct a similar survey at home and then extend it to your apartment and make your neighbours also energy-wise.
