Objective<\/h5>\n\n\n\n

To analyse the electricity usage of your own shelter.<\/p>\n\n\n\n

Outcome<\/h5>\n\n\n\n

Students will get an idea about the most energy intensive devices in their homes, and how they can reduce energy consumption from these devices. <\/p>\n\n\n\n

Requirements<\/h5>\n\n\n\n

Electrical appliances in household, monthly\/bi-monthly electricity bill.<\/p>\n\n\n\n

Prerequisites<\/h5>\n\n\n\n

 <\/em><\/strong>A conceptual knowledge of energy consumption. Electrical energy requirement and consumption of the appliances or machines at one\u2019s own house.<\/p>\n\n\n\n

Procedure<\/h5>\n\n\n\n

Step 1: <\/em><\/strong>Identify all the electrical appliances in your home.<\/p>\n\n\n\n

Step 2: <\/em><\/strong>Look for nameplates on each appliance.<\/p>\n\n\n\n

Step 3: <\/em><\/strong>Note down the value of power consumption mentioned on the nameplate of each appliance.<\/p>\n\n\n\n

Step 4: <\/em><\/strong>Estimate average daily operation hours of each appliance for the previous month. Multiply it by 30 or 60 (based on whether you get a monthly or bi-monthly bill) to get monthly\/bi-monthly operation hours.<\/p>\n\n\n\n

Step 5: <\/em><\/strong>Estimate the monthly\/bi-monthly electricity consumption of each device by multiplying power consumption with operation hours.<\/p>\n\n\n\n

Sample Calculation:<\/p>\n\n\n\n

Calculate the cost to run the appliance<\/p>\n\n\n\n

Annual\/Monthly cost = Energy consumed annually\/Monthly x rate of utility per kWh<\/p>\n\n\n\n

Using the above formula, let us find the annual cost to operate an AC.<\/p>\n\n\n\n

    \n
  • Run time per day: Let us assume that it is summer and you run the AC for 7 hours a day for lets say 20 days a month.<\/li>\n\n\n\n
  • Wattage: You will find the wattage on the label or the user manual. Let us assume it as 1500 W.<\/li>\n\n\n\n
  • Energy consumed daily: (1,500 x 7) \u00f7 1,000 = 10.5 kWh<\/li>\n\n\n\n
  • Energy consumed annually: Let us assume you run the AC for 200 days in a year.<\/li>\n<\/ul>\n\n\n\n

    10.5 kWh x 200 = 2,100 kWh<\/p>\n\n\n\n

      \n
    • Annual cost: Let us assume the utility rate is 12 rupees per kWh<\/li>\n<\/ul>\n\n\n\n

      2,100 x 12\/kWh = 25,200 INR per year .<\/p>\n\n\n\n

      Considering this as a sample calculation, calculate the electricity consumption of other appliances in your household.<\/p>\n\n\n\n

      Step 6:<\/em><\/strong> Add the electricity consumption from all the appliances to get an estimate of monthly electricity consumption of your home.<\/p>\n\n\n\n

      Step 7:<\/em><\/strong> Tally this value with the electricity consumption of last month\/ two months, mentioned in the electricity bill. Both values should be close.<\/p>\n\n\n\n

      Step 8:<\/em><\/strong> Identify the three most energy intensive appliances in your home, based on their energy consumption.<\/p>\n\n\n\n

      Step 9:<\/em><\/strong> Reflect on the ways in which you can decrease the energy consumption of these appliances in order to reduce your bill. <\/p>\n\n\n\n
