Answer :
To calculate CO2 emissions from using a 4,913-watt heating pad for 26 minutes, convert the energy usage to kilowatt-hours and then multiply by an emissions factor. The total comes to approximately 1.1 kg of CO2.
To calculate the amount of CO2 created by using a 4,913-watt heating pad for 26 minutes, we first need to find out the total amount of energy used in kilowatt-hours (kWh). We then convert this to an equivalent CO2 emission using an average emission factor generally provided for a region’s electricity mix.
Step 1: Calculate the energy used in kWh. Since power is given in watts and time in minutes, we convert time to hours.
Energy (kWh) = Power (kW) × Time (h)
Energy (kWh) = (4,913 W / 1,000) × (26 min / 60)
Energy (kWh) = 4.913 kW × 0.4333 h
Energy (kWh) ≈ 2.13 kWh
Step 2: Convert energy used to CO2 emissions. The global average emissions intensity for electricity generation is around 0.5 kg CO2 per kWh.
CO2 Emissions (kg) = Energy (kWh) × Emission factor (kgCO2/kWh)
CO2 Emissions (kg) = 2.13 kWh × 0.5 kgCO2/kWh
CO2 Emissions (kg) ≈ 1.065 kg
Rounding to one decimal place, the CO2 emissions are 1.1 kg.
