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

To calculate the GHG emissions pertaining to one\u2019s own household energy usage. <\/p>\n\n\n\n

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

Students will gain knowledge on their house\u2019s total GHG emissions and realize what contributes maximum to the emissions based on the electrical audit. <\/p>\n\n\n\n

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

Power meter, Electricity bills.<\/p>\n\n\n\n

Prerequisites<\/h5>\n\n\n\n
    \n
  • Students should have conducted the \u2018Energy Audit of Own Shelter\u2019 Activity before this activity. <\/li>\n\n\n\n
  • Fundamental knowledge on use of power meter. <\/li>\n<\/ul>\n\n\n\n
    Procedure<\/h5>\n\n\n\n

    Step 1: <\/em><\/strong>Taking the \u2018Energy Audit\u2019 activity further, make a list of every electrical appliance used in one\u2019s house along with its wattage details and electricity consumption. In case, it is not mentioned on the appliance and is not available on the company website as well, students can take the reading using power meter.<\/p>\n\n\n\n

    Step 2: <\/em><\/strong>Use the emission factor details and the formula given below to calculate GHG emissions of their consumption.<\/p>\n\n\n\n

    Step 3: <\/em><\/strong>Identify appliances responsible for maximum consumption and discuss strategies to reduce the consumption.<\/p>\n\n\n\n

    Given Data<\/em><\/strong><\/p>\n\n\n\n

    Electricity cost: Rs. 4.2\/kWh<\/em><\/strong><\/p>\n\n\n\n

    Electricity GHG Emissions: 1.33 kg CO2e\/kWh (cBalance Emissions Factor Database)<\/em><\/strong><\/p>\n\n\n\n

    GHG emission in tCO2e = Electricity consumption (MWh)  X  GHG emission factor (kgCO2e\/year)<\/em><\/strong><\/p>\n\n\n\n

    Sample Calculation<\/em><\/strong><\/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 annually<\/p>\n\n\n\n

      GHG Emissions for 1 AC of 1 tonne = 2.1 MWh x 1.33 = 2.793 = 2.8 tonne CO2e per year<\/strong><\/p>\n\n\n\n
