Question
If a person uses 1 unit of electricity, 1 kg of LPG gas, and 1 litre of petrol in a day then how much CO2 will be emitted in a day? about 3 kg of CO2 about 5 kg of CO2 about 7 kg of CO2 about 9 kg of CO
Solution
To answer this question, we need to know the average CO2 emissions per unit of each energy source.
-
Electricity: The CO2 emissions from electricity can vary greatly depending on the source of the electricity. However, on average, the US Environmental Protection Agency estimates that 1 kWh of electricity generates about 0.527 kg of CO2.
-
LPG Gas: According to the UK government's conversion factors, burning 1 kg of LPG gas produces about 3 kg of CO2.
-
Petrol: The US Energy Information Administration estimates that burning 1 gallon (about 3.785 litres) of petrol produces about 8.887 kg of CO2. Therefore, 1 litre of petrol would produce about 2.35 kg of CO2.
Adding these up, a person using 1 unit of electricity, 1 kg of LPG gas, and 1 litre of petrol in a day would emit about 0.527 + 3 + 2.35 = 5.877 kg of CO2 in a day.
So, the closest answer to the options given would be about 7 kg of CO2.

When any fossil fuel is burned it produces emissions of carbon dioxide and water vapor. A typical household in a developed country will use approximately 70 kWh per month of electricity for computing and electronics. Each kWh of average coal burned produces 2.23 kg of carbon dioxide emissions while natural gas produces just 0.91 kg per kWh of carbon dioxide.How many more kg of carbon dioxide are produced by the coal plant compared to the natural gas plant from the computing and electronics alone, from a household over the course of one year?
